Sailboat vs Catamaran Comparison

1. stability:.

• Sailboat: Embraces the classic elegance of a single hull, providing a responsive and traditional sailing experience. The tilting motion, counterbalanced by the daggerboard, adds a dynamic element to the journey.
• Catamaran: Boasts unparalleled stability with its two hulls, virtually eliminating the pronounced tilting effect. The absence of deep keels and ballasts enhances agility and lightness, offering a smoother ride. Ideal for those who are prone to experiencing a bit of seasickness!
• Catamaran: Defines spaciousness, providing individual cabins with dedicated bathrooms. The square-shaped dinette mirrors domestic proportions, and the substantial, well-equipped cockpit encourages social gatherings.
• Sailboat: Offers a cozy and intimate setting, utilizing space efficiently. While cabins may be more compact, the sailboat's design fosters a close-knit atmosphere among passengers.
• Catamaran: Impresses with a wide footprint, enhancing onboard living space and comfort. The challenge lies in marina space during peak seasons, offset by the freedom to enjoy extended periods aboard without the need for frequent shore visits.
• Sailboat: Navigates marinas with ease due to its narrower profile. While confined space might limit interior room, the sailboat's ability to find berths becomes advantageous during bustling harbor seasons. It's worth noting that this characteristic can vary depending on the model; for instance, new models such as the Bavaria C38 or the Dufour 44 (premiered in Düsseldorf and soon available) feature generous beams, providing more space, especially in the main front bedroom, and creating a general feeling of larger spaces, even on the deck.

4. All on the Same Level:

• Catamaran: Integrates the dinette and cockpit seamlessly, creating a harmonious, unified space with a transparent sliding wall. Visual continuity fosters a connected and inclusive experience among guests.
• Sailboat: Embraces a more compartmentalized layout, allowing for distinct areas that cater to different activities. This provides passengers with varied environments throughout the vessel.

5. Manoeuvrability:

• Catamaran: Exhibits impressive maneuverability, thanks to two engines that facilitate precise control in tight spaces. The ability to turn within its own axis is particularly advantageous in crowded harbors.
• Sailboat: Requires careful and deliberate maneuvering in harbors due to its single engine. While agility might be reduced, the sailboat's sailing capabilities shine when navigating open waters.

6. Speed and Sailing:

• Catamaran: Hydrodynamically efficient hulls offer superior speed, especially in upwind sailing conditions. The catamaran excels in providing a swift and enjoyable journey, minimizing the impact of adverse weather.
• Sailboat: Demonstrates versatility in sailing conditions, adapting well to upwind challenges. While not as inherently fast as a catamaran, the sailboat's overall speed ensures an engaging sailing experience.

7. Comfort on Board:

• Catamaran: Appeals to first-time sailors seeking a home-like experience. Offers disengaged and domestically oriented spaces, ensuring privacy between hulls—a valuable feature for those with varying daily routines or sailing with a skipper or children.
• Sailboat: Fosters a more communal atmosphere, ideal for passengers who enjoy close interaction. The sailboat's compact layout promotes shared experiences among travelers.

8. Autonomy:

• Catamaran: Slightly compromised autonomy due to weight sensitivity. Limited fuel independence and water reserves necessitate more thoughtful planning. The presence of two engines enhances maneuverability, allowing for precise navigation.
• Sailboat: Excels in fuel autonomy, providing extended sailing periods without the need for frequent refueling. A single-engine simplifies maintenance and promotes straightforward, self-sufficient voyages.

9. Organisation of Space:

• Catamaran: Typically designed with a standardized layout, catamarans for charter often feature two cabins in each hull, strategically positioned at the extreme bow and stern. This layout, with two bathrooms centrally located, offers a consistent and practical accommodation setup. Innovative models feature an exterior galley integrated into the cockpit, providing a unique blend of space and functionality.
• Sailboat: Boasting a more versatile structure, sailboats come in various layouts to cater to diverse preferences. Modern designs challenge traditional constraints with generous beams. This not only enhances interior space, especially in the main front bedroom but also creates a broader and more open atmosphere on the deck. The flexibility in cabin arrangements allows for a personalized and comfortable sailing experience, accommodating different preferences and needs. Ultimately, the organization of space on a sailboat is influenced by the specific model chosen, allowing for a tailored approach to onboard living.

Catamarans excel in rough seas, thanks to their twin-hull design providing enhanced stability and reduced heeling compared to monohull sailboats. The unique architecture allows for increased speed and maneuverability, making them efficient in navigating challenging conditions. 

Key to their rough-sea capabilities is the bridge deck —the space between the hulls—featuring ample clearance in well-designed catamarans. This minimizes slamming, enhances seaworthiness by reducing structural stress, and ensures a smoother ride in turbulent sea states. 

While catamarans can capsize in extreme situations, proper design, operation, and the skill of an experienced captain contribute to their overall capability in handling a variety of sea conditions, ensuring a secure and enjoyable sailing experience, even in rough seas.

A sailing catamaran and a power catamaran differ primarily in propulsion . A sailing catamaran relies on sails, offering a traditional experience with stability and efficiency. In contrast, a power catamaran uses engines, emphasizing speed and ease of handling. Power catamarans are chosen for faster cruising and covering more miles.

Catamarans are often considered faster than monohull sailboats due to their hydrodynamic design . With two hulls providing stability, reduced drag, and a wider beam for efficient sailing angles, catamarans excel in speed. However, sailboats showcase versatility, excelling in certain conditions such as upwind sailing. Overall speed comparison depends on various factors, including design and wind conditions.

Sailing a catamaran is often seen as less challenging for beginners due to inherent stability and reduced heeling. The dual-hull design provides balance, making catamarans forgiving in terms of capsizing. While novices appreciate stability, adjustments are needed for maneuvering and handling increased windage. Proficiency comes with practice, and experienced sailors may find catamarans offer a refreshing change in sailing dynamics.

Catamaran VS Sailboat, 9 Important Differences You Should Know!

This is one of the never-ending questions out there, catamarans vs. monohulls (also known by some just as sailboats). The discussions are wild and are, many times, really hard to follow unless you’re already a vivid sailor. By then, you probably already have your own opinion on what the differences are.

In this post, I’m trying to take a little more pragmatic approach to describe the 9 most important differences that I think you should know about.

Table of Contents

1. Catamarans Have Two Hulls, Sailboats or Monohulls Have One

This is the most apparent feature that strikes you when you look at the two boats next to each other; one has two hulls, and the other only one. Mono, as you might know, means one (1).

Having two hulls also implies you need something that connects them, making the boat look a little bit like a manta ray, or is that only me?

2. Monohulls Will Rock From Side to Side

Catamarans don’t heel (leaning to its side in boat language). Therefore, they offer a very different sailing experience, which is more stable and usually more comfortable; this also applies when staying at anchor. The catamaran will move around with the wind, always staying flat, while the sailboat will rock from side to side and might even get you seasick .

This is especially noticeable when the wind is opposing the waves, making the boat have the wind pushing it from one side and the waves banging it from the other side. This makes for a very uncomfortable anchorage on a monohull. Basically, you are the iron, and the wind and wave are your hammer and anvil, not a perfect place to be.

3. Catamarans Offer More Space for the Same Length

For the same length of boat, let’s say 40ft, you’re getting a lot more space on a catamaran. This is due to the two hulls, but also the big deck that attaches the hulls. There will also be even more space on the outside of the boat, both fore and aft of the mast. In between the bows, you will have either a solid deck or trampolines , which will greatly increase the space.

4. Catamarans Make Horrible Noises While Sailing Upwind

The distance between the water surface and the deck’s underside is called bridge deck clearance ; if it is not big enough, even small waves will start smashing into the underside.

This repeated cycle of waves hitting the boat does induce not only great noise but also a lot of vibrations and discomfort to the crew.

This problem is something that just doesn’t exist on monohulls (only one hull) and also is a strong argument from those who prefer monohulls.

The noise might not be a big deal when traveling coastal waters for a few hours a day, but consider going days on end straight into the wind, hearing that banging noise, ad a little motion sickness, and you will pretty soon wish you were on a monohull 🙂

5. Monohulls Are Slower Than Catamarans

At least that is the short answer, this applies if we only compare the length of the boat, but if we compare the total length in the water, it’s a different story. Much of this speed comes from the decreased drag, bigger sails, and a catamaran’s lesser weight.

Here are some articles when you want to better understand catamaran speed:

• Cruising catamaran speed
• Fastest cruising catamarans
• Catamaran hull speed calculator
• Are trimarans even faster than catamarans?
• 20 Performance cruising catamarans

6. Catamarans Offer Less Helm Feedback

One big benefit of having a boat that heels is that it’s a great way to get feedback on whether or not the boat is overpowered. Since a catamaran stays flat, it is harder for a new captain to understand when to reef.

This could be a safety issue for those transitioning from monohulls to catamarans, which I believe is the most common way people acquire a catamaran.

7. Monohulls Are Harder to Dock

For a monohull to turn, it needs enough water passing around the rudder; for enough water to pass around the rudder, the boat needs to be moving. So this means once you stop your boat, you can’t turn; the things that move you are the wind and the current. This is the tricky part with a monohull, the timing needs to be perfect, or you’ll either go too fast and hit the dock, or you’ll go too slow and drift away.

On a catamaran, that’s different, you see; now you have two engines, much like a battle tank, you can now make a 360 turn on the spot. This means you can do a full stop, put one engine in forward and one in reverse, making the boat spin on its axis. That’s great! I wish my car would do that.

8. Catamarans Are More Fuel-Efficient

Saying a catamaran is fuel-efficient is like saying your Ford F150 truck is fuel-efficient. But, in comparison to its one-hull brother, it’s true, this really needs a lot more explanation for it to be a fair comparison, but only considering the lengths of the boat, the catamaran will consume less fuel.

This is mostly a consequence of the less drag a catamaran has since the weight is distributed over a greater area.

• Catamaran fuel efficiency data contributed by owners
• Electric vs gas: outboard engines. Which is the best?

9. Catamarans Offer More Comfort

Since catamarans have more space and don’t heel as much, they offer a more comfortable experience. One beautiful aspect of having a big deck is that you can hang out in the trampolines; they are basically two big hammocks, and since hammocks already are great, putting them on a boat makes them awesome.

And since it doesn’t heel, you can also freely move around on the boat without spilling your drink or being at risk of falling overboard. This also means that going inside to cook is a treat since you don’t have to cook while trying not to fall over.

Looks and Other Factors

All in all, catamarans are great, but so are monohulls; there are also many other factors that I haven’t mentioned yet; these are mainly factors of the heart.

Many people feel that it isn’t real sailing if it isn’t done like it was in the good old days, heeling over and all. And to some extent, I can totally agree with that, but on the other hand, enjoying those two trampolines while on a sunny weather cruise down the bay is something I can’t forget.

And also the looks, catamarans look great; I think they look and almost move like those manta rays you can see down in the Bahamas. On the other hand, there is not much cooler than seeing a solid old monohull dig deep into the waves and go almost straight into the wind; what a feeling!

Are you planning your next sail but unsure what type of boat is best suitable for you? Two of the most popular vessels we offer our customers are sailboats and catamarans, but both are quite different from each other.

Making the right decision is essential to ensure you have the best experience possible when you book with sailyachts.com. So that you do, we’ve designed this guide to break down sailboats vs catamarans to assist you with your decision-making.

What Is the Difference Between a Sailing Catamaran and a Sailboat?

Catamarans and sailboats are two very different types of vessels when you consider the way they’re made, their features, and how they perform on water.

Before you make any concrete decisions about a catamaran or a sailboat with Sailyachts .com, you should be aware of the differences between them as well as the similarities.

Sailboat VS Catamaran

Differences, size and space.

Catamarans are much more sizable than sailboats; they’re often equipped with more cabins, have various bathrooms scattered throughout the boat, and the sailor’s cabin tends to be bigger on them, too. As for the interiors and living space, they provide more, too, with expansive kitchens and communal zones; they’re practically floating House.

Whereas, if you look at our sailboats, they’re Usually smaller, offering a cozier feeling, and the cabins are rather compact compared to what you’d find on a catamaran. That’s why they’re extremely popular among couples hiring a yacht with us.

If you’re after stability, catamarans will be better suited for you due to their two hulls, which protect the vessel from tilting when it hits heavy waves out in the Mediterranean. Additionally, they don’t have any deep keels and ballasts which protects the boat from struggling in shallow waters and adds an extra layer of steadiness.

Sailboats only have one hull, so they’re prone to tilting more when they encounter waves. They need a deep keel and ballast to keep things balanced. Unfortunately, this makes sailing in shallow areas a bit more difficult and puts the boat at more risk of rocking. However, if you like a bit of action, you might enjoy it.

Versatility

Since catamarans have two engines, it makes them easier to maneuver, especially in tight areas, making visits to hidden locations less of a hassle. However, depending on the model, the size may impact how versatile it is.

When you’re operating a sailboat, you better be prepared for measured controls and timed movements because of their limited ability because of their single engine.

The one thing all sailors want to know is how fast their boat will be. Catamarans are faster than sailboats since they have a hydrodynamic design, which is particularly favorable when sailing upwind.

Sailboats aren’t exactly slow; they are just catamarans that are a lot faster and more powerful. So, even if you hire one, you’ll still have the chance to live out your James Bond moment.

Similarities

The sails on both catamarans and sailboats are similar. On both types of vessels, the sailor will need to use the sails in the same way to leverage the power of the wind to move the ship when it’s in the ocean.

So, if you’ve only sailed one type before, you’ll be easily able to understand how the sails on the other work.

Rudders are one of the main components needed for a ship to be able to steer its course. Catamarans and sailboats have them in order for the captain to be able to go in the direction they want. However, they must be operated in line with the sails, so the captain must carefully coordinate the angle of the rudder with the trim of the sails.

Pros and Cons of Sailboats and Catamarans

Advantages and disadvantages of sailboats.

• They require less fuel, making your sail more cost-effective than it would be on a catamaran.
• Sailboats are more affordable to rent for a week with sailyachts.com than catamarans.
• They provide a classic sailing experience paired with an exhilarating adventure.
• Compared to catamarans, they’re easier to anchor.

Disadvantages

• If you’ve no sailing experience, they can be hard to operate.
• Bumpier out at sea than catamarans.
• They’re more difficult to sail in shallow waters.
• They’re better suited to smaller groups since they’re less roomy, and the cabins tend to be more compact.

Advantages and Disadvantages of Catamarans

• They offer much more luxury amenities than sailboats, such as large communal areas, sunbathing space, etc.
• They tend to provide extra space and additional cabins.
• Easier to operate if you’re a first-time sailor.
• Sailing with a catamaran gives an extra layer of stability in the ocean, so the ride is less bumpy.
• Catamarans are faster than sailboats.
• Catamarans are more expensive to hire with sailyachts.com for a week than sailboats.
• It’s harder to find an available catamaran since they’re more popular.
• With a catamaran, it can be difficult to find somewhere to anchor during the high season since they’re larger and take up more space.

How Much Does a Sailboat Cost Compared to a Catamaran?

While prices of both types of boats vary based on the time of year you book your rental and where you pick it up, catamarans are the priciest option.

The minimum you’d pay for a catamaran is around €4000 per week during the low season. If you wanted to hire one during the high season, it could cost more than €10000 per week.

Our sailboat prices are much more affordable than catamarans; for one week, you can find a rental for as low as €2,000 a week throughout the low season, but if you want to hire it during the high season, the prices can go up over €6500 per week.

Be aware that these fees are without any crew members. If you’ve no sailing experience or don’t have a valid license, you’ll need a captain onboard, which costs €220 each day. Additionally, adding extra crew members to take care of the day-to-day operations on the ship will cost an extra €170 each day for every member.

Catamaran vs Sailyacht: Which One to Choose?

As you can see, our catamarans and sailboats offer two very different but exciting experiences for customers.

Small parties, such as couples or groups of friends, tend to enjoy sailboats more because of the intimacy they provide. It’s a more authentic sailing trip; imagine crashing against the waves in a traditional monohull, where it’s just your nearest and dearest, alone without disturbance.

Catamarans are winners for bigger groups like families. They’ve got so much more space and cabins, and the level of luxury that comes with them is unmatched. You’ll feel like a true VIP on one of our catamarans when you’re sailing along the French Riviera, catching waves alongside the rich and famous.

Final Words

So, that’s our analysis of the battle between sailboats and catamarans. Now, the decision is up to you, which one will you go with? Is it going to be an easy-to-manage sailboat or a luxurious catamaran with lots of space and extra comfort?

If you’re still unsure which option is best for you, you can contact one of our team members today on our Contact Us Page, and we will go through both of the options with you in depth to find the right solution.

While the make and model of the vessel are great determining factors in which is the fastest of the two, in general, catamarans tend to be faster than sailboats. The main reason for this is catamarans' hydrodynamic design. Additionally, their two hulls add stability to their sails, allowing them to pick up speed much faster than sailboats.

" class="elementor-tab-title" data-tab="2" role="button" aria-controls="elementor-tab-content-1" aria-expanded="false" tabindex="-1" aria-selected="false"> Are Catamarans Harder to Sail Than Sailboats?

Due to their stability, catamarans are seen as an easier sailing option than sailboats. There's much less of a chance of you capsizing in one than a sailboat. However, if you've enough experience, taking on the challenge of operating a sailboat can be an exhilarating and fun experience.

" class="elementor-tab-title" data-tab="3" role="button" aria-controls="elementor-tab-content-2" aria-expanded="false" tabindex="-1" aria-selected="false"> Is a Catamaran Smoother Than a Sailboat?

Anyone who prefers a smooth sail rather than a bouncy outing should opt for a catamaran. Their dual hulls, combined with minimum heeling and wide base, work well with providing sailors and passengers a calm voyage. But remember, if you do end up finding yourself in choppy conditions, there's only so much these things can do for you, so always take care when you're in the ocean.

" class="elementor-tab-title" data-tab="4" role="button" aria-controls="elementor-tab-content-3" aria-expanded="false" tabindex="-1" aria-selected="false"> Is a Sailboat or Catamaran Better?

There's no right or wrong option when it comes to sailboats and catamarans. It's more about the type of sailing experience you're after and how big the group that's joining you for your trip is. Catamarans are better for multi-day trips with family and friends to faraway picturesque islands. They're comfortable, stable, and often come with modern features and facilities, but they're also the most expensive option of the two. Those who don't mind a bit of rocking from time to time and aren't overly fussed about the level of comfort will prefer sailboats. Avid sailors, in general, prefer sailboats because operating them is more of a challenge, which adds an element of excitement to the adventure. Along with that, they're also cheaper and are more readily available at the ports we operate out of.

The Ultimate Guide to Choosing Between a Sailboat or Catamaran for Your Sailing Adventures

C hoosing between a sailboat and a catamaran for your sailing adventures is a significant decision that depends on various factors, including your sailing preferences, experience level, budget, and intended use. Here's an ultimate guide to help you make an informed decision:

1. Sailing Experience:

• Sailboats: Typically require more skill and experience to handle, especially in adverse weather conditions. Ideal for sailors who enjoy the traditional feel of sailing and are willing to invest time in learning and mastering the art.
• Catamarans: Easier to handle, making them suitable for beginners. The dual-hull design provides stability, reducing the learning curve for those new to sailing.

2. Space and Comfort:

• Sailboats: Generally have a narrower beam and less living space. However, some sailboats may offer comfortable cabins and amenities.
• Catamarans: Wider beam creates more living space. Catamarans often have multiple cabins, spacious saloons, and expansive deck areas, providing a more comfortable living experience.

3. Stability:

• Sailboats: Monohulls can heel (lean) while sailing, which some sailors enjoy for the thrill but can be discomforting for others.
• Catamarans: Greater stability due to the dual hulls, providing a more level sailing experience. Reduced heeling makes catamarans suitable for those prone to seasickness.

4. Performance:

• Sailboats: Known for their upwind performance and ability to sail close to the wind. Some sailors appreciate the challenge of optimizing sail trim for efficiency.
• Catamarans: Faster on a reach and downwind due to their wide beam. However, they may not point as high into the wind as monohulls.
• Sailboats: Typically have a deeper draft, limiting access to shallow anchorages and requiring deeper marina berths.
• Catamarans: Shallow draft allows access to shallower waters and secluded anchorages, providing more flexibility in cruising destinations.
• Sailboats: Generally more affordable upfront, with a wide range of options available to fit different budgets.
• Catamarans: Often more expensive upfront due to their size and design. However, maintenance costs may be comparable or even lower in some cases.

7. Mooring and Docking:

• Sailboats: Easier to find slips and moorings in marinas designed for monohulls.
• Catamarans: Require wider slips and may have limited availability in certain marinas, especially in crowded anchorages.

8. Intended Use:

• Sailboats: Ideal for traditional sailors who enjoy the art of sailing, racing enthusiasts, or those on a tighter budget.
• Catamarans: Suited for those prioritizing comfort, stability, and spacious living areas, especially for long-term cruising and chartering.

9. Resale Value:

• Sailboats: Generally have a more established resale market, with a wider range of buyers.
• Catamarans: Growing in popularity, and well-maintained catamarans often retain their value.

10. Personal Preference:

• Consider your personal preferences, the type of sailing you plan to do, and the kind of lifestyle you want aboard your vessel.

In conclusion, both sailboats and catamarans have their advantages and disadvantages. Your decision should be based on your individual preferences, experience level, budget, and intended use. If possible, charter both types of vessels to experience firsthand how they handle and to help make a more informed decision based on your own preferences and needs.

• First time on a catamaran: what you need to know

During your captain training, you'll have learnt how to manoeuvre a monohull sailboat . But what about when you have the opportunity to sail a catamaran?  Find out everything you need to know, including differences from monohulls, important factors to consider, pros and cons, and recommended destinations and catamaran models. If you're new to catamaran sailing, this is the perfect guide for you.

5 reasons to rent a catamaran

What are the main reasons why someone decides to sail on a catamaran? Here are the top benefits of choosing this type of boat.

1. Stability

The double hulls of a catamaran provide exceptional initial stability, allowing it to  remain afloat and stable in rough waters and wind. If you're looking for a smooth and peaceful sailing experience, especially with small children or seasickness-prone individuals, a catamaran is a great option. It's perfect for taking along your grandma or a nervous friend who's never been on a boat before.

YACHTING.COM TIP: Getting seasick is not only a major worry for novice sailors, but also holidaymakers on a boat trip. But it even can affect experienced sailors from time to time. Those with darker humour say it has two phases — in the first phase you become so sick you're afraid you're dying, and in the second, you're afraid you're not going to. The important thing, though, is to understand why it happens and try to prevent it. Although you'll significantly reduce suffering from seasickness on a catamaran, what works best if it does occur? Find out in our guide —  How to cope with seasickness .

A catamaran offers more space than any other boat of similar length. With spacious saloons , plenty of seating and lounging areas , and ample sunbathing spots (such as the netting known as the  trampoline ), you'll never feel cramped. The cabins are roomy and the bathrooms are as big as those in many apartments. People who dislike tight spaces or value their privacy will find a catamaran ideal. On larger models (50+ feet), you'll have so much space, you may have trouble finding each other. Despite its comparable length, a catamaran always feels larger than its monohull counterpart. If you're used to a 50-foot sailboat, try a 45-foot catamaran and you'll still feel like you have more space.

3. Amenities comparable to a hotel room

Not only are the cabins spacious, but they are also comfortable and cosy. They usually come equipped with high-quality bedding, pillows, shelves, reading lamps, and more, making them feel like a proper room. That's why we wrote an article highlighting 9 reasons why a sailing holiday is better than staying at a hotel and it's doubly true with a catamaran.

4. Added extras

Catamarans often come equipped with the latest technology and gadgets. These include solar panels, generator, a seawater desalinator, a modern plotter with GPS, and autopilot . These will make you more self-sufficient at sea without needing the facilities of a marina as often.

5. Shallow draft

The reason why catamarans are so popular with sailors, especially in exotic countries , is the very shallow draft — 0.9 to 1.5 metres, depending on the length of the vessel, which means skippers don't have to concern themselves so much about hitting the seabed. While caution and monitoring charts are still necessary, it provides greater freedom in choosing anchorage spots, allowing you to sail almost right up to the beach and anchor to enjoy the peace and tranquillity.

Only small fishing boats can get as close to the shore as catamarans.

Sailors have differing preferences, with some sticking to single-hulled boats and others preferring catamarans. In fact, which is best has been a hot topic since sailing began. This makes understanding the benefits and drawbacks of each hull design essential so you can make your own choice.

1. Rental price

One major drawback of catamarans is their higher cost on the charter market. Single-hull sailboats can be rented for 1,000-2,500 euros per week, while a well-maintained catamaran typically starts at 3,000 euros per week. However, this may not be the case for all models.

2. Capacity

The higher cost of catamaran charters is offset by the extra space, comfort, and capacity — it can often hold up to 12 guests comfortably. This results in a per-person cost comparable to sailboats and cheaper than coastal hotels, making them popular for island cruising and party boats. However, for a safe and responsible party experience, we recommend checking out our guide — How to enjoy a party on a boat: 10 tips to keep your crew and your boat safe .

YACHTING.COM TIP: Never exceed the maximum capacity of the boat. And remember that even small children count as crew members.

3. Port charges and marina fees

Keep in mind that having two hulls means a wider boat, leading to higher docking fees . This increased width can take up more space than two smaller sailboats. However, the cost per person can be offset by the fact that more people can be accommodated. 

4. Speed vs. consumption

Catamarans typically feature two high-powered engines , making them faster than similar-sized sailboats. Even without the power of the wind, you can be flying across the waters and with a better fuel efficiency than motor boats.

Catamarans typically have two basic sails: the mainsail and the foresail and operating them follow similar principles as on single-hulled sailboats. Self-tacking jibs can also be used, reducing the work required to trim and manoeuvre the sails. 

For those looking to enhance their sailing experience, a gennaker can often be rented with the catamaran, providing added benefits, especially in light wind conditions. Take a look at our 5 reasons to rent a gennaker .

6. Flybridge

This elevated deck is a common feature on catamarans. Here you'll find the helm station and sometimes additional seating or lounging space. It is a valuable addition that provides extra living space on the boat.

Who is the catamaran suitable for?

Catamarans are the preferred choice for a group of friends wanting a laid-back holiday on the water but are also popular for corporate team-building events  and specialised stays like yoga. As their spacious deck provides a safe play area for children , they are also ideal for multi-family vacations.

YACHTING.COM TIP:  If you are sailing with small children, safety is paramount. So, check out our guidelines for safe boating with kids , our article on how to survive on a boat with kids , the Skipper mom logbook: sailing with a baby and always try to stick to the 4 essential tips for smooth sailing with kids . If you don't have kids or don't want to bring them along, why not take your four-legged friend? Catamarans offer ample space for dogs to run around, and following these 7 tips can help make your pet a true sea dog.

On the other hand, we wouldn't suggest a catamaran to sporty sailors to chase the wind in, as the catamarans for charter aren't intended for racing or regattas. Due to their design, they have limited upwind capabilities (sailing boats can sail up to 30° wind angle, while charter catamarans can only handle up to 50° to 60° wind angle), making them unsuitable for competitive sailing.

YACHTING.COM TIP: If you have doubts about your ability to safely operate the boat, consider hiring a skipper. We can arrange a skipper for you who is knowledgeable about the area and can take care of the navigation for you or teach you any sailing skills you may be lacking. Remember when planning that the skipper will occupy one cabin or berth in the saloon. 

Specifics of sailing on a catamaran

The principles of sailing a catamaran are similar to those of a monohull sailboat, but there are some differences to keep in mind. These may have already been covered in your captain's training course.

Travelling on the engine

A catamaran has two motors , each of which can be controlled separately using its own throttle control. Want to turn on the spot? That's no problem at all with a catamaran — simply add throttle with one motor and reverse with the other. Once you get the hang of this trick, you'll no longer need a bow thruster, although catamarans are sometimes equipped with one. This makes docking your catamaran a breeze compared to single-hulled sailboats.

Travelling on the sails

Sailing varies mainly in what courses you can sail and how strong the winds are. Most charter catamarans perform best on courses at 50 to 60 degrees to the wind. This is a greater angle compared to sailboats. So be prepared to have to adjust your planned route.

If you sail a sailboat too hard, the boat itself will tell you that you've over-steered by heeling. A catamaran won't do that, so you have to be very attentive to when to reef the sails. Usually, you will put in the first reef at a wind speed of 18 to 20 knots and the second reef at 23 to 25 knots.

Best destinations for catamaran sailing

In addition to the more traditional locations of Croatia , Greece , Italy ,  Spain and Turkey , we rent catamarans all over the world. In these destinations, you appreciate plenty of space , comfortable access to the water via steps, stability on the waves and amenities such as a barbecue and air conditioning .

However, catamarans are perfectly suited for more exotic destinations . In remote locations, the low draft comes in particularly handy as the seafloor is often poorly charted and the beaches are stunning. The large water and diesel tanks, along with an electricity generator, a desalinator to produce fresh water from seawater, and solar panels are especially useful in exotic locations where the yachting infrastructure is less developed. These features help sailors to be self-sufficient and avoid the need to find a dock every few days.

Popular destinations for catamaran sailing include the beautiful Seychelles , Thailand , French Polynesia and the Caribbean (Grenada, St. Lucia, Martinique, Antigua, St. Martin, Cuba , British Virgin Islands, Bahamas, and Belize).

The most popular catamarans

Popular charter catamaran brands include Lagoon , Bali , Fountaine Pajot , Nautitech , and Leopard . These are the models that have received positive feedback from our clients for years and that we confidently recommend.

The Lagoon 380 offers a true sailing experience, or the larger Lagoon 46 , where you may end up spending the whole morning lounging in its spacious cabin.

The Bali cat space  provides amazing seating up at the helm.

The Fountaine Pajot Elba 45 where you'll enjoy relaxing at the bow on the seating or the trampoline.

The Nautitech 46 with its huge saloon.

The Leopard 45 with its gorgeous bright interior, or the Leopard 50  that's so luxurious, you'll feel like a king.

YACHTING.COM TIP: For the discerning sailor, the Lagoon 620 and Dream 60 large catamarans are also worth mentioning. However, it's important to note that most captain's licenses are not valid for these giants and you'll need to hire a professional skipper.

Special types of catamarans

Catamarans have been around for quite some time, leading shipyards to continuously innovate and create new models with unique features and characteristics. So, what are some of them?

Power catamaran

The popularity of power catamarans has been increasing lately due to the fact that they provide the stability and spaciousness of a catamaran without the need to handle sails.

Do you believe that more is always better? Not satisfied with just two hulls? Then we have a unique chance for you to rent a trimaran , a three-hulled catamaran that offers an unparalleled sailing experience. Trimarans are still rare, so you're sure to attract attention wherever you go.

Catamaran Or Monohull? 27 Important Facts (Explained)

Catamarans and monohull boats are two very different kinds of vessels.  Each craft offers distinct advantages and disadvantages that you’ll want to consider before choosing between the two.

In this post, we’ll go over some of the important things to consider when choosing between catamarans and monohull boats:

Table of Contents

Cost & Availability

Both catamarans and monohull boats come in small recreational sailing versions, larger motorboat versions, and larger sailing models.  In all cases, the catamarans will cost more and will be harder to find.

The reason catamarans are harder to find because there are not as many of them, and they’re mostly made overseas.

Also, there aren’t as many catamaran manufacturers, so sailors have fewer options when buying them.

On top of this, catamarans have only recently become popular in the United States and other areas of the developed world.  This means the used market for boats doesn’t have as many catamarans on it.  You might find that you have fewer options when making a used catamaran purchase, which could bring costs up to a premium.

Two Times The Fun with Catamarans

Another reason that catamarans are more expensive than monohulls is the fact that catamaran buyers have to purchase two hulls, two engines, and two of all of the components that help make an engine work.

Traditional sailboats and large powerboats with one engine don’t have this cost issue.

On top of this, a catamaran is much wider than a monohull, and thus you have more space to build and equip.

On the other hand, once you’ve purchased the boat, you do get to enjoy the benefits of having two of everything.  We’ll talk about the advantages of this further down in this post.

Maintenance Cost Makes A Difference

The maintenance on a catamaran is also more expensive than the maintenance on a monohull boat.  This goes back to the fact that there is twice as much of everything to maintain.

Catamaran owners will need to do preventative maintenance on two different engines, and they’ll have two hulls and a large deck area to clean and maintain as well.  If they’re getting the bottom of the boat treated, they’ll have to do this twice (once for each hull).

Even the interior components can usually be found twice.

Each cabin will usually have a head in it, so you’ll have at least two toilets and sinks to maintain, which obviously has its plusses and minuses.

One positive aspect of this is that catamaran owners do have the option of deferring some of their maintenance.  For example, if one head is no longer functioning properly, you always have the second one that you can use.

It also adds a bit of safety as well.

This is because while the catamaran does have two engines to maintain, the owner does have power even if one of the engines happens to go down.

Some catamaran owners also like to point out that maintenance may not have to be done as frequently.  This is because the engines don’t have to work quite as hard, and other items like additional bathrooms and sinks might only be used half as much.

How Much Space Do You Need?

A catamaran has more space than a monohull.  This is because the boat is wider, and it has a much larger deck area.  It also has twice as many hulls, so you have more overall space between the two of them.

The additional space is great for people looking to throw parties on their boats.

Most boat owners would agree that the catamaran is usually the party boat of choice at the docks.

Even if you aren’t into throwing parties, the extra space can still be nice for relaxing on the deck or getting a suntan.  The wide-open space also makes it easy to use the boat as a fishing platform.

Additionally, you have more space for stuff like surfboards, rafts, and other items that can easily clutter up the deck of a monohull.  Even fishing can be easier from a catamaran as the deck provides plenty of space between different anglers.

Catamaran owners also have additional space for carrying fresh water and adding generators and solar panels.

Interior space is generally more plentiful on a catamaran, and luxury catamarans have an easier time fitting large items like washers and dryers inside of them.  You can have these on larger monohulls as well, but it will be harder to make them fit than it is in a catamaran.

On the other hand, all of the additional space means the catamaran owner has more space to maintain and clean.  Also, all of the additional items that can be brought onto the boat will make it heavier.  A heavier boat will use more fuel, and it will travel more slowly.

Living Quarters Vary Between The Two

The living quarters on a catamaran are much different than they are on a monohull.  Most people would agree that the berths in a monohull are much more spacious than in a catamaran.

A monohull offers people the opportunity to have a large bed with space on either side to walk around it.  This is great for couples who want to get out of bed without waking up their partner.

Catamarans, on the other hand, have the advantage of being able to offer large above-deck salon areas.  The galleys, the dining areas, and the living areas can all be above-deck, while the two hulls can provide heads and berths.

Some boat owners say that living in a monohull is akin to living in a basement apartment .  Other boat owners prefer the monohull because it brings them closer to the water and gives them the feeling of being at sea.

Privacy Can Be Prioritized On Catamarans

A catamaran offers up many different living areas that people can take advantage of.  For example, each hull will typically have its own bathroom and bedroom.

This gives each sleeping area complete privacy from the other.

The living quarters are usually up on the deck, so early risers can wake up and move to these quarters without waking up the others.

The same holds for night owls.  A night owl can stay up late without bothering the people who want to retire to their beds earlier.

With two hulls, large catamaran owners can hire a crew and give them their own hull to live in so that there is separation between the cruisers and the crew.  This is a wonderful advantage for honeymooners looking to have their own space.

The downside to all of this, of course, is that sometimes a family may not want the additional privacy.  For example, a family with small children might not want their children in a different hull than they are.

Additionally, the extra privacy can make it hard for people on the boat to communicate.  This could become a big problem in the event of an emergency.

For this reason, it is often recommended that each hull have a radio in it so that the occupants can quickly communicate with each other.  Remember, even in inland areas, cell phone reception may not be very good inside the boat hulls.

Recreation In a Monohull vs. a Catamaran

Most sailors agree that sailing a monohull boat is much more exhilarating than sailing a catamaran.  Traditional sailboats heel, and sailors get instant feedback while they’re sailing.  For the most part, catamarans stay stable, and you don’t get the same feeling with the movement of the wind and the water.

When it comes to monohull powerboats, you have the advantage of being able to pull water skiers, kneeboarders, and tubers with ease, as long as the boat has the power and a planing hull.  A power catamaran usually doesn’t have the speed or maneuverability to pull off these recreational opportunities because they are displacement hull designs.

Catamarans excel in more leisurely recreational activities.  A catamaran makes a great party deck as well as a great cruising deck.  Catamaran owners can comfortably walk around a catamaran without having to worry that the boat might knock them over the next time it decides to heel.  This allows boaters to sit and talk with one another comfortably.

A catamaran can also be used as a beaching vessel.  This makes it a great platform for people looking to go swimming or fishing around sand bars and other shallow water areas.  It also makes it a great boat for sailors looking to sail a larger boat on a river or lake known for having shallow areas.

Swimming and Diving

Swimming and diving off of a catamaran are usually much easier than doing the same from a monohull.  The wide stance of the two hulls offers boat designers the option to put in staircases at the back of both hulls.

In between these staircases, some boats will have an additional diving platform and/or a dedicated frame for pieces of equipment and dinghy storage.  This makes catamarans great for swimmers, snorkelers, and divers.

On the other hand, modern monohull sailboats can also have good transom stairs for easy access to the dinghy and swimming.  Both types of boats can easily travel far out to sea, giving boaters the option of diving in areas that can’t be accessed from beaches and developed areas.

Boat Draft In Shallow Waters

For the uninitiated, the boat’s draft refers to how deep the boat’s hull sits within the water.

A monohull typically sits deep within the water, while a catamaran sits much higher on the water.  This is why we stated that a catamaran is good for shallow waters.

The advantage of having a boat that can go into shallow waters isn’t restricted to just recreational activities like swimming and fishing.  A boat that can go into shallow water is safer to operate in areas where a boat with a deeper draft might become damaged.

Additionally, a catamaran has more stability on calm waters.  This helps make a catamaran more comfortable to relax or sleep on while at anchor or the dock.

The deeper draft of a monohull boat has its advantages as well.  A deeper draft provides more stability in rough waters and allows a boat to go further into the sea.

For this reason, many coastal cruisers will prefer catamarans, while many ocean voyagers will prefer monohull boats.  In fact, some areas of the Caribbean and the Florida Keys can be off-limits to boats with deep drafts as it simply isn’t safe for the boat to navigate these waters.

This isn’t to say that you can’t navigate these waters in a monohull boat, but you will have to be cautious depending on how deep your monohull’s boat draft is.  You wouldn’t have this issue in a catamaran.

Stability On The Sea

A catamaran offers a lot more stability in shallow waters, in calm waters, at the dock, and anchorage.  This makes the boat great for cruising and for relaxing in port.

A monohull offers a lot more stability in rough waters.

This makes this boat great for heading out to sea and for navigating vast distances.

Safety Issues To Consider

Both catamarans and monohulls can be built to navigate the waters they were made for safely.  This will be determined more by the boat’s category designation rather than the type of boat.

However, each boat deals with unsafe situations in different ways.  For instance, a monohull boat is likely to right itself if it is capsized.

This means that even in rough seas, you’re unlikely to find yourself permanently capsized.

The downside to this is that should you become completely swamped from a capsize in a monohull boat, you are much more likely to sink.  In fact, if there is a hull breach on a monohull boat, your boat could sink.

Catamarans are said to be unsinkable.  This isn’t completely true, but it is very unlikely that a catamaran will sink.  Even if a hull is breached, you still have a second hull to keep the catamaran afloat.

However, a catamaran can’t right itself.  If you capsize your catamaran, it will stay capsized.

One other safety concern to consider is that a monohull sailboat will heel while a catamaran will not.  This increases the chances that someone could fall off the boat or onto the deck in a monohull boat.

Catamarans Are Faster Than Monohull Boats

A catamaran is faster than the average monohull boat.

This is because they face less water resistance, and their narrow hulls don’t have to deal with their own bow waves as a monohull does.

Of course, catamarans aren’t always faster.  Old cruising catamarans may not go faster than 8 knots, and modern monohulls can exceed 10 knots.

Monohull boats tend to sail downwind and in choppy seas better than catamarans.  This gives them a speed advantage during ocean voyages.

We have a separate post with complete average speeds per type of catemaran . It’s a must read if you are at all concerned about speed!

Fuel Consumption Considerations

Catamarans have two engines to burn fuel, which can drive up fuel costs.

However, a catamaran is lighter on the water, so it usually takes less energy to move a catamaran.  This means you’ll end up using less fuel in a catamaran than you would in a monohull.

On top of this, catamarans can decide to use just one engine in low wind areas.  This further decreases the amount of fuel that a catamaran consumes.

These rules only apply to calm waters.

A monohull navigates waters with high waves and strong winds much more efficiently than a catamaran.  In this case, you’ll use less fuel in a monohull than you would in a catamaran.

Sailing Differences To Notice

Sailing a monohull boat can be exhilarating.  These boats can glide through choppy waters, and you get to feel the motion of the boat as the sea rushes by the cockpit and the wind causes you to heel.

This type of sailing also provides instant feedback as you’ll know what you need to do with the sails as you’ll feel what is going on through the boat’s motion.

Sailors all over the world have been using monohull sailboats for years, and you’ll find plenty of outlets for recreational sailing with a monohull sailboat.

Sailing catamarans do not heel like a monohull sailboat.

These boats, therefore, do not provide the sailor with instant feedback.  Also, if you incorrectly sail a catamaran, you do risk capsizing the boat more easily.

Training Can Be Quite Hard

Sailing a catamaran and sailing a monohull boat are two different experiences.  People looking to sail either should probably get professional training.

Obtaining this training will always be easier with a monohull boat.

This is because monohulls are more popular, so you’ll have more instructors available to you.

Do You (Or Your Friends) Get Seasick?

People who are prone to getting seasick easily might want to consider a catamaran.  A catamaran provides much more stability in calm waters, and you get a lot less movement.

On the other hand, people who are not prone to getting seasick might prefer a monohull in choppy waters.

This is because a monohull will deal with deep and choppy waters with high waves much better than a catamaran will.

As a result, a catamarans movement can seem extreme under these types of conditions.  People who have never gotten seasick before can end up sick under these conditions.

Here’s a separate article we wrote with everything you should know about seasickness on Catamarans . There are some things you can do and some things you should know!

Docking Is (Usually) Easier With A Monohull Boat

Docking a catamaran can be a difficult endeavor.

This is because catamarans are often too wide to be docked within the slips located in central areas of a marina.

Because of this, they need to be docked at the end of the dock.  This leaves them with fewer spots to dock.  It also makes docking more expensive.

Catamaran owners traveling through areas that are unlikely to have many catamarans in them may find it difficult to find a dock at all.  This is true in areas of the northern Atlantic where monohulls are much more popular than catamarans.

Storage Issues To Consider

Even storing a catamaran can be more difficult.  This is because storage facilities often do not have the equipment to get a catamaran out of the water.

The wide width of these boats requires special lifts, and not all boat marinas will have them.

Storage facilities that do get the catamaran out of the water will often charge more money for it.  They’ll charge additional fees for taking the catamaran out of the water, and they’ll charge additional fees for the actual storage of the boat as well.

Redundancy And Backup Equipment

We touched upon this earlier, but it is worth repeating that catamarans have many redundancy built into them.  This can be a big advantage when it comes to safety.

For example, if one rudder becomes inoperable, the boat can still be steered with the other one.  If one engine becomes inoperable, the boat can still be driven with the other one.

In extreme cases, a hull could become damaged, and you could still stay afloat because the other hull will keep the boat safely above water.  These safety advantages can save lives and keep people from becoming stranded out at sea.

The primary downside is the maintenance issue that we mentioned earlier.  All of these redundant components will need to be maintained.  As a result, maintenance costs will be close to twice as expensive in a catamaran.

Cooking Is Easier On Catamarans

Cooking on a catamaran is usually easier than it is on a monohull.  The main reason for this is that a catamaran doesn’t heel like a monohull, so you don’t have to worry as much about things falling over.

This not only makes cooking easier, but it makes cooking safer as well.

Additionally, catamaran galleys tend to have more space in them to move around.  Also, they are often up on the deck, so you don’t have to climb in and out of the hull with your dinner in hand.

Dinghy Storage

Monohulls and catamarans can both hold dinghies.  The larger the boat, the larger the dinghy can be.

However, catamarans have a wide area at the rear of the boat that is perfect for holding dinghies.

This makes getting in and out of the dinghy easier.  Also, people can often have larger dinghies on their catamarans because the boat’s stern is so accommodating.

Power Generation Is Easy On A Catamaran

A catamaran has a lot of space for solar panels and wind turbines.  Rigid panels can be placed in areas that won’t be walked on, like overtop of the bimini, and flexible panels can be placed in areas where the panels might end up getting stepped on.

The width of a catamaran even gives them more opportunities to put hydro generators into the water.

This means catamarans can generate more power than the average monohull boat can generate.

On the other hand, a monohull usually has less powered items to worry about.  Monohulls need less power to operate at full capacity, so you may not need all of the additional space for generating power.

Ventilation Issues To Think About

Some people feel that monohull boats don’t offer enough ventilation.  This is especially true in warmer areas of the world.

Catamarans also lack ventilation within their hulls, but fortunately for them, much of the living space is located up on deck.  This gives catamarans an edge when it comes to cruising in warm weather.

On the other hand, monohull owners aren’t exposed to the cold winds that you might find up on deck in harsher climates. 

This lack of airflow may actually be of benefit in this instance.

Some people find monohulls to be better looking than catamarans and vice versa.

This all comes down to personal preference, so you’ll have to decide for yourself which type of boat has the advantage in this case.

Some people think catamarans are the most elegant thing in the world while others prefer monohull boats as they look more classic.

Resale Value Is An Important Factor

If you read our extensive guide to boat depreciation per boat type , you know that no matter what boat you buy, it will always go down in value.  This is just a sad fact of boat ownership that people need to consider before buying a boat.

Many factors go into how much you’ll be able to get for your boat when you resell it.  These factors are the condition of the boat, the age of the boat, and the economy in general.  For example, people are less likely to want to buy boats during a recession.  This is especially true when it comes to smaller boats.

However, one additional factor that catamaran owners need to consider when thinking about resale value is the value of the dollar. 

People from the United States don’t have many American catamarans to choose from and will usually need to buy these overseas.

This means that a catamaran will be less expensive to buy when the dollar is strong compared to the Euro and more expensive to buy when the dollar is weaker in comparison.  This will affect the used market as well because higher values on new catamarans can help to bring up the value on the used market.

With a monohull boat, you may not have to consider situations like this as there are makers of monohull boats all over the world.

Don’t Let The Length Trick You!

One thought to keep in mind when comparing monohull boats and catamarans is that their different shapes account for different space advantages.

For example, a 40-foot long catamaran will have much more cubic space than a 40-foot long monohull.

Because of this, when comparing boats, you should look at the cubic space rather than the length. In this case, you may be comparing a 48-foot long monohull with a 40-foot long catamaran.

When you compare the two types of boats in this manner, the price differences aren’t quite as large, and the comparison is fairer.  It also may make the operating and maintenance costs more similar.

This is an important distinction to make because the length of the boats can trick you!

Consider Trying Both (Before Buying)

Boats can be an expensive purchase, so it makes sense to try them out before you decide to make your purchase.

Rent each type of boat and use it on the types of waters that you intend to cruise on the most.

Try the boat out in different weather conditions as well, and don’t be afraid to do multiple rentals before you make your final choice.  The time and money invested into making sure you get the boat you really want will be more than worth it in the end.

Catamaran vs. Monohull: We Changed, Should You?

There are two schools of thought when it comes to monohull versus catamaran . We have done extensive cruising and lived aboard two monohulls and four catamarans over the past 25+ years . We experienced the good and the bad for both single hull and multihulls first hand. Quite honestly, the pluses for catamarans far outweigh the minuses. There are multiple benefits of catamarans. They are faster, more stable and spacious, and have shallower drafts allowing safer anchorage closer to shore. Being on a stable platform with no heeling cuts down on crew fatigue and seasickness leaving the crew more alert and in control of the vessel. Even novice sailors feel more confident on catamarans.

When we built our monohull Royal Salute in the early 90s, catamarans were not established and were looked upon with extreme suspicion by most cruisers, including ourselves. “Safety and the capsize” issue were always the first things to come up against sailing catamarans. It is a fact that monohulls can get rolled in heavy seas but will right themselves because of the heavy lead keel, and while crew and vessel will be battered, the roll is survivable.

However a catamaran once capsized, will remain upside down (jokingly referring to this state of the catamaran as “reaching its most stable position when upside down”). The inability of a catamaran to self-right was and still is a major bone of contention. However, what is not often discussed is that a monohull has about a 5,000 pound keel of lead that is constantly trying to drag the boat to the bottom of the ocean versus a catamaran that has no ballast and is in most cases with modern catamarans, unsinkable.

So the options are to either sail the world on a boat that, if it springs a leak, will sink like a stone or a vessel that cannot self-right in the event of a capsize but will not sink no matter what. So from a practical point of view, here are our observations over the last 25+ years of living aboard, on the advantages and disadvantages of a catamaran.

ADVANTAGES OF A CATAMARAN

1. speed equals safety.

The speed of a catamaran makes it possible to outrun bad weather. While catamarans do not point as high into the wind as a monohull (or if it does, it makes more leeway or slides sideways), it is about 20% faster than a monohull. This means that even if you sail upwind at a slightly wider angle to the wind than a monohull and have to cover more distance, you will still arrive at your destination long before a monohull.

A modern performance catamaran with daggerboards and good quality sails will point as high as a similar sized monohull. It will point the same as a comparable monohull and sail much faster and therefore arrive at an upwind position much sooner than a the monohull. It is important to note that most of the production catamarans on the market are under-powered and are equipped with standard smaller sails. In lighter breezes many of these designs perform poorly unless fitted with bigger headsails, a Code Zero and a square-top mainsail.

While we believe that more comfortable and safer in rough weather , we have to concede that when the weather gets really bad (60 knots of wind or more) we would personally prefer to be on a monohull from the standpoint of surviving. I would say that a monohull is preferable for serious offshore single-handed sailing because you can more easily hove-to in a monohull. We have been in some extreme weather on a number of catamarans and never really felt that we were in danger, although it takes some nifty seamanship.

A monohull could capsize in extreme weather or even roll in a storm, but they generally come back upright. A catamaran on the other hand, will not right itself. But the cat will generally stay afloat, offering a good place to survive while you wait out the storm or until help comes along. Well-designed modern catamarans are very hard to capsize though.

Having said all that, most catamarans can do 200 to 250 miles a day and with modern technology allowing one to pull down weather at will, there is no good reason why you should get caught in extreme weather. A faster boat is a safer boat as it will in many cases be able to outrun bad weather. With good weather routing information a catamaran can avoid most serious weather and, at worst, place itself in the most favorable position to avoid the brunt of a storm.

2. A Catamaran is a Stable, Safe Platform Underway

Catamarans have no ballast in the keels like monohulls do and therefor it relies on beam and buoyancy for stability. Typically cruising catamarans will have a beam to length ratio of roughly 50%, although many designs nowadays exceed the 50% rule of thumb. So, a 45-ft long catamaran will be about 22-ft wide, providing a very stable platform when sailing. Unlike catamarans, monohulls cannot overcome the rolling and pitching with their narrow beam and the lead ballast for stability.

This rolling and pitching makes the deck on a monohull very unsafe whereas on walking around on the deck of a catamaran while underway is far easier since the boat is much more stable, and it doesn’t heel. This makes sail changes and reefing much easier and a lot safer for the crew. Without the rolling and pitching motion, the danger of falling overboard on a catamaran is considerably less than on a monohull.

3. Crew Fatigue Reduces on a Catamaran

Because a catamaran does not heel over like a monohull, it offers far more comfort underway because the motion is mostly fore and aft pitching and very little beam-to-beam rolling. On all points of sail, a catamaran tracks upright and significantly reduces crew fatigue and seasickness. Seasickness is usually caused by things like anxiety, fatigue, hunger and cold, which all add to a sense of disorientation. This leads the crew to making bad decisions and seamanship errors that could be fatal to the crew and vessel. The more stable platform of the catamaran will hugely keep those issues at bay, making the crew more alert and energized.

Every action and chore including cooking is much easier on a catamaran when underway. It is much more pleasant to be on the deck level looking out rather than being stuck “down below.” It is also much nicer to sleep on a boat that doesn’t heel. I remember nights at sea in our monohull when I was rolling around in my bunk unless I was properly wedge in a little corner. That is simply not the case on catamarans.

All these factors ensure that your crew will not expend unnecessary energy to simply try and stay upright, onboard and safe on a long passage. Your crew on a catamaran will be well rested and alert and will be able to function well if a stressful situation arises.

4. Comfort at Anchor

Catamarans provide a wide platform and therefore offer lovely spaces to relax at anchor without the rolling motion that monohulls have a tendency to do in a swell. During our 15 years of cruising on a monohull, we have often had to leave anchorages that we really were not finished exploring because of a rolly, uncomfortable anchorage. Big rollers or swells coming into an anchorage can make conditions in an anchorage very uncomfortable and unsafe.

We were anchored off Funchal on the island of Madeira in our monohull Royal Salute once, when we were forced to leave our anchorage. The rolling became so bad, we were rolling from gunnel to gunnel. The anchorage became untenable to remain anchored, forcing us to go out to sea in foul weather in the middle of the night. This is an extreme case but believe me, we have left many an idyllic anchorage because of a rolling swell into the anchorage. Catamarans, on the other hand, do not roll from like monohulls have a tendency to do and are far more comfortable at anchor.

5. Anchor Bridal Setup

Catamarans are fitted with a bridle, attached to both bows and down to the anchor chain, resulting in a very stable position at anchor. What we found with our monohull was that because the bow acts as a sail (because of the high freeboard), the boat tended to sail at anchor in high winds. It sailed in one direction until the chain snatched and tacked over and sailed in the other direction, feeling like it might dislodge the anchor altogether. The catamaran on the other hand sits at anchor a lot more stable and doesn’t sail around as much.

6. Ease of Boarding on a Catamaran

Thank goodness we were much younger and more agile during our monohull days. Royal Salute and most monohulls of her generation or older, have high free-boards, making it quite a feat to get onto the boat from the dinghy. It was one of the most challenging things to do because unlike the more modern monohulls that have a scoop at the back, we had to climb up on the side of the boat to get on and off. We, of course rigged steps, etc. but it was always a hassle compared to the ease of getting on and off a catamaran from a dingy or from the water.

7. Shallow Draft Equals Better Anchorages

Catamarans have significantly shallower drafts than monohulls, allowing for safer anchorages closer to shore. Most catamarans in the 40-ft to 50-ft range draw between 3-ft to 4.5-ft, so they can anchor in places that a monohulls can not even consider. In the shallow waters of the Bahamas for example, the catamarans have a big advantage. We often anchor our own catamaran just a few feet away from a beach. It definitely allows one to be able to explore areas where the water is shallow without the fear of running aground.

The shallow draft also allows for emergency repairs in shallow water and even doing the bottom job when the tide goes out as we have done in places like Mtwapa Creek in Kenya, East Africa. The catamaran easily rests on her keels on the sand without help making it a breeze to do the “annual haul out” even in remote locations.

8. Dinghy Davits & Dinghy Size

All catamarans have a set of davits that make it very easy to raise and lower the dingy. Our monohull and most cruising monohulls do not have an efficient or easily accessible set of davits. This makes raising and lowering the dingy an elaborate production. Catamarans on the other hand, has davits systems easily accessible and some even have platforms to rest the dinghy on.

The lack of beam and difficulty of lifting the dinghy also limits the size and type of dingy that one can reasonably carry on a monohull. As we all know, the dingy is your transport to and from shore and diving or fishing spots, so the bigger and faster the dingy, the better off you are. A catamaran can carry both a heavier and bigger dinghy which makes the popular center consul dinghy so much more possible.

9. Interior Space and Comfort on a Catamaran

We sailed 32,000 NM on our 45-ft monohull, happy as clams, not realizing that sailing does not have to be done lying on your ear 24/7 while on passage or sitting knee-to-knee in the cockpit at anchor with your two other guests at the dinner table! One can liken sitting in a monohull cockpit to sitting in an empty Jacuzzi, you are always nice and close to the other folks.

Now that we are on our fourth catamaran, there are a few things that have become more evident to us than the incredible space and comfort of a catamaran, not only at anchor but also underway. The cockpit and living space in general are huge compared to a monohull, making for very comfortable and spacious living conditions. It feels more like you are at home, rather than just on a camping trip.

Knowing that one spends at least 90% of one’s cruising life at anchor, it’s important to have good open living space, which most modern cats nowadays offer. A lot of cats have walk around beds, lots of storage, every modern appliance including washer/dryer, etc. However, one has to fight the urge to fill the space if you want to keep the cat light and fast.

Sailing with guests onboard for extended periods of time, in close quarters can become claustrophobic but on a catamaran people are spread out and separated. With guests sleeping in one hull and the owners in another, catamarans offer much more privacy and separation. Some cats even have privacy doors that will close off the entire hull and has a separate entrance onto the deck, which really separates you from the guests completely.

There is very little heeling on a catamaran, so there is no need for hand grips and safety harnesses inside the boat. There is nothing better (and safer) than being able to walk from the cockpit into the living room (saloon) on one level or one step down at most. In a monohull, when heeling at a severe angle, you would have to claw your way from the companionway steps down to the living area, while fighting to stay upright, significantly tapping your energy.

Unless you hit extreme conditions, everything stays put on a catamaran reducing the anxiety before doing passages of having to stow and secure everything. This very issue makes a lot of cruisers reluctant to weigh anchor and explore more often. It is just too much effort to pack away all your stuff once comfortable in an anchorage!

One thing you will notice is that the stove on catamarans are not gimbaled like it is on monohulls and this should tell the story in itself. The stability and comfort on a catamaran is far superior. Cooking is easy and safer. I often open a nice cold beer, put it down to do something and forget about it only to find a warm beer later in the same place I left it. This is not something that happens on a monohull.     

10. Redundancy on a Catamaran

Unlike monohulls, catamarans have a lot of critical redundancies. That of course means two hulls to clean and anti-foul, double the engine maintenance, etc. but having two of the critical equipment like engines for instance, outweighs the downside.

With two engines, if one fails you still have adequate propulsion to go anywhere. If by some fluke the second engine also fails, you have a full set of spares to fix at least one of them. Our friends once hit a sleeping whale off Tanzania, and when it dove, it hit the prop, bending it. They limped into the narrow channel on the one engine but at least they could make it to a safe harbor where we surveyed and repaired their damage.

We often only use one engine when motoring while making passage in order to conserve our fuel. The one engine is totally capable of moving the boat along at a good speed unless you are in heavy seas and you may need more power. Other than that we only use two engines to dock or maneuver the boat in close quarters.

Because there are two engines there are also two independent charging systems via the alternator on each engine. If one alternator goes out, there is still another complete charging system. There are two rudders and if one fails or falls off (as has happened to our friends on a monohull off Columbia, where they almost lost their boat) you have a second rudder that is completely capable of steering the boat by itself indefinitely. That holds true for several things on a catamaran!     

11. Maneuverability

The engines are spaced far apart on a catamaran and it makes maneuvering much easier and more precise than monohulls, unless the monohull has a bow thruster. We did not have a bow thruster (not many monohulls do) and had to rely on prop-walk and using prop wash on the rudder. A modern catamaran can do a 360 turn on her own axis. A monohull cannot do this and have a bigger turning circle. However, a monohull under sail is much more maneuverable and certainly will tack a lot faster than a catamaran. The ease in maneuverability under engine on a catamaran in close quarters specifically, is vastly superior comparatively.

12. Rigging

Because of the beam on a catamaran the spinnaker pole has become unnecessary equipment. Hallelujah, I say. That pole on our monohull was a pain the behind and I always hated having to use it. On a catamaran, one can fly an asymmetrical cruising chute or spinnaker, using the bows to tack the clew or run a guy through a block so it is very much simplified, easier and safer.We also sail wing-on-wing with twin headsails when we sail downwind. We use our furling jib and furling Code Zero. It is as easy as one, two, three.

DISADVANTAGES OF A CATAMARAN

1. bridgedeck slamming.

One advantage most monohulls do have when underway is that they don’t slam. Catamarans with a low bridgedeck clearance can experience significant slamming in confused seas sailing upwind. This slamming can be quite disconcerting when you first experience it as we did on a Shuttleworth 44 design, our first ever catamaran experience, 20+ years ago. At times, it felt as though the boat was falling apart. Of course the boat was fine but nevertheless, the stress on the crew from the constant noise and discomfort was significant.

Monohulls don’t have a bridgedeck which means no slamming and are therefore a bit more comfortable than l ow bridgedeck catamarans when beating into severe confused conditions or “washing machine” conditions as we call it. Modern catamarans mostly have better bridgedeck clearance and the slamming is significantly less. However, not all cats have a good clear tunnel under the bridgedeck. Some manufacturers build beds into the bridge deck in order to make more space in the chest of the catamaran where the slamming occurs. These protuberances into the bridgedeck tunnel will likely increase slamming. So be mindful of that when selecting a catamaran. We currently own a Bali 5.4 and the bridgedeck clearance on this boat is more than adequate and the tunnel is clear. We therefor experience very little slamming compared to our Prout 45 that we previously owned (picture of sister ship below) with a much lower bridgedeck.

We Explain Bridgedeck Clearance

In the pictures below, the Bali 5.4 has very good clearance from the water to the bridgedeck and has a nice clean tunnel versus the very low bridgedeck of the Sunreef 50. 

2. Sailing Downwind

Monohull spreaders are set at 90 degrees to the mast whereas a catamaran has to have backswept spreaders. The reason is that, on a monohull, there is a backstay and using this, plus the intermediates you can get a nice pre-bend in the mast (the pre-bend is to flatten out the main sail and allow for better performance).

On a catamaran with no back stay, you need to use the back swept spreaders and the diamonds to pre-bend the mast. The reason I point this out is because on a catamaran, if you want to broad reach or run, the mainsail cannot be let out all the way because the backswept spreader tips could punch holes in the fabric.

On a monohull, the spreaders are at 90 degrees so you can let the main and the boom out much further which is, of course, much more effective. This is one of the reasons it is better to broad reach and tack downwind on a catamaran.

Whether a monohull or multihull, sailing dead downwind doesn’t usually make great VMG. Therefor a regular cruising cat, much like a monohull, needs a lot of sail area and has to sail deep downwind if it is to achieve a decent speed made good (VMG). This video demonstrates how we achieve this by sailing wing-on-wing downwind.

It is more difficult to find a dock either as a transient or a permanent slip for a catamaran in general because of the wide beam. But this is changing fast and will soon not be too much of an issue. In the USA dockage is charged by the length of the boat in feet, so there is no disadvantage there but, in some places, (the Mediterranean for example), dockage is charged at length times one and a half because of the additional beam.

Since the catamaran is stable at anchor, we mostly anchor out. We have more privacy, a better breeze and usually a stunning view.We have a nice dinghy with a good outboard engine and is big and comfortable enough to get to shore fast and together with the modern conveniences like the generator, watermaker and washer/dryer, docking becomes a non-issue.

It is definitely more difficult to find a travel lift with enough beam for a catamaran for a haulout, while, for a monohull, there are absolutely no problems anywhere. The wide beam of cats also greatly limits the number of shipyards that can haul them out. Most catamarans over 40-ft must be hauled out with a 50-ton travel lift. This not only increases the cost of the haulout, but greatly limits the choice of the shipyards for repairs and maintenance. With limited choice, prices are high for shipyard services.

Catamarans do tend to have a lot more windage than monohulls. This can be an issue especially when maneuvering in close quarters with a strong wind. But I have found that, provided the engines are powerful enough for the size of catamaran, that twin engines negate this problem. Also, many modern large catamarans now have a bow thruster fitted. It is super easy to dock.

The cost of getting into a catamaran is much higher than that of monohulls. That could put a serious dent in your cruising kitty or require you to put your dream on hold a little longer. Pre-owned monohulls on the other hand are very cheap to buy comparatively, because the supply presently far outweighs the demand.

Catamarans are in high demand and they typically hold their value much better and longer and the trend is now heavily in favor of the catamaran market. When prospective buyers contact us for catamarans under $250,000 the choices are very limited and catamarans under $100,000 is near impossible to buy. In this case, your best bet is to go with a monohull unless you go with much older boats like the Prouts or the less expensive Geminis.

Our Own Catamarans & Monohulls

FYI: Royal Salute , a Bruce Roberts 45 monohull, was the first boat we owned and sailed approx. 30,000NM on. Mythral, a Seafarer 30, was our “toy boat” while we were waiting for our catamaran to be built. Even though this classic little monohull sailed around the world, it didn’t have much in modern conveniences like running water. Siyaya was an Island Spirit 40 catamaran that we sailed from Cape Town to Florida on and then taught live-aboard sailing classes for several years. Zuri I was a Prout 45, a beautifully crafted catamaran but by today’s standards is considered old technology. Our Lagoon 450 SporTop ( Zuri II ) is a fantastic live-aboard catamaran. We lived and taught aboard her for three years but sold her last year and we currently own a Bali 5.4 ( Zuri III or Z3 as we call her now). Read about our various boats .

CONCLUSION: CATAMARAN vs MONOHULL

We were dyed in the wool monohull sailors for 15+ years. We loved the pretty lines of monohulls, the sailing ability and what we believed at the time to be much safer vessels. However, now that we have been avid catamaran enthusiasts, we simply can never go back to monohulls. Catamarans have come of age and with modern technology have overcome most objections that sailors of old had against them. They are well designed and built, are safe, and we simply love that they sail fast and upright. There is not a whole lot to dislike about a catamaran when you live aboard. We have weighed all the pros and cons of catamarans and found that the pros far exceed the cons. We made the change to a catamaran and do not regret it one bit!

We hope that this article will clear things up for all the prospective catamaran owners out there.

4 thoughts on “Catamaran vs. Monohull: We Changed, Should You?”

I read that the engineering on the catamarans were improved over the years. Whats the oldest year would you recommend designwise?

Scott, my apologies for the late reply. We’ve been traveling in Africa. Anyway, catamarans have come a long way and improvements in technology is happening at lightning speed. I reckon that even the older model catamarans are good. It depends on what your needs are. If you want something a little better performance wise, I would go for something no older than 15 years.

After buying a catamaran what is the difference in expense of a catamaran vs a monohull. Many articles state that not only the initial cost of a catamaran is more it the operating cost as well.

Hi Todd, it is more expensive. The annual dockage and haul out as well as maintenance will be more expensive. You obviously have two engines to maintain and various other pieces of equipment to service in both hulls. While there is more equipment there is also more redundancy and of course you have the comfort factor. So, depending on your situation, it’s probably worth it.

Power Catamarans vs Sail Catamarans, What’s the Right Choice For You?

• January 13, 2015

Sail and power catamarans are both great boats with distinct advantages. To choose what is best for you, think about how you will be using the boat. The good news is they both work with the Business Yacht Ownership approach.

Sail Catamarans

• Sailboats are better if you want to follow the sun or do longer range cruising.
• With the right prop and engine, sailboats can do 9-10 knots and are very sea-worthy. They provide comfort at sea. If you just feel like laying back and relaxing, you can almost forget the mast is there. But, when the conditions are ideal, you will be able to sail. New designs and technological advancements make sail handling easier than ever.
• Sailboats are quiet and promote socialization. Generally, they can handle more guests at a time, whether they are socializing or sleeping.
• Sailboats cost less per cubic ft. of volume. The Helia 44 has as much or more room/volume than the Cumberland 47.

Power Catamarans

• They have low clearance. If your cruising plans involve a bridge with height restrictions, a power boat may be the better option.
• A properly, dedicated purpose catamaran powerboat gives significantly better speed and range than a comparable monohull powerboat.
• The Fountaine Pajot Motor Yacht offers the exceptional characterics of the catamaran platform, giving you a very comfortable ride and virtually eliminating rolling at anchor.
• The Fountaine Pajot Power cat is less expensive to run than a monohull and can compete with the economy of a trawler. The power cat also offers the efficiency of the hull, which allows you to go faster when you need to (up to 22 knots or so). This is not possible under normal conditions with a trawler or sailing cat.

Sailboat Data Comparison: Monohulls vs. Catamarans

Published by oceanwave on august 18, 2023.

Ah, the sea—a vast body of water that beckons with freedom and adventure. As you stand at the shore, gazing at the horizon, a thrilling question arises: What vessel will carry you into the heart of this blue realm? The decision between monohulls and catamarans in the world of sailing presents an alluring conundrum. It’s a decision that intertwines design, performance, and the very essence of your sailing experience. Imagine harnessing the wind’s force, feeling the salt on your skin, and surfing the waves with grace. But hold on, let’s take a closer look at the fascinating comparison between these two sailing giants before you lift the sails.

Have you ever thought about:

What are the dimensions and stability differences between monohulls and catamarans?

What do the figures indicate about their acceleration, flexibility, and interior volume?

What secrets do the LOA, draft, beam, and SA/D ratios unveil about your chosen path?

Welcome to a voyage of discovery, where sailboat data becomes a compass guiding us through the depths of comparison. Join us as we raise the sails of knowledge and explore the complex waters of design. We will solve the puzzles surrounding the dimensions, stability, and performance of well-known monohulls and catamarans using thorough analysis and practical examples. As we embark on this journey, prepare to uncover the essence of each vessel and find the answer to the question that lingers at the heart of your sailor’s soul: Which vessel will become your gateway to boundless horizons?

Sailboat Data Comparison

Those who enjoy sailing are frequently forced to decide between monohulls and catamarans. Due to differences in design, size, and performance, each variety offers a distinctive sailing experience. In order to assist you in choosing a boat that matches your preferences, let’s check out Sailboat Data Comparison on monohulls and catamarans.

Length Overall (LOA) Comparison

Analysis:   Catamarans typically have a longer overall length (LOA) than monohulls. Catamarans are a desirable option for those seeking comfort and roominess due to their additional length, which frequently translates to more interior space.

Stability Comparison

Analysis: Compared to monohulls, catamarans typically have shallower drafts and wider beams. They can sail effortlessly in shallower waters thanks to their exceptional stability, which is a result of this. In some circumstances, monohulls may perform better to the windward due to their deeper drafts.

Sail Area-to-Displacement Ratio (SA/D) Comparison

Analysis:   Comparing sailboat data to monohulls, catamarans frequently have a higher Sail Area-to-Displacement Ratio (SA/D). This suggests that catamarans may be able to use the wind more effectively, leading to faster speeds. The specific design and sail plan, however, are equally important in this regard.

Comparing the Experience: Beyond the Numbers

Although Sailboat Data Comparison can provide insights, choosing between monohulls and catamarans requires more than just numerical comparisons. Due to their deep drafts, monohulls may perform and maneuver more effectively during upwind sailing. They provide a classic sailing experience by heeling in response to the wind’s force.

On the other hand, stability and space are valued more highly in catamarans. They can easily venture into remote anchorages and shallow waters thanks to the shallower draft. They are well-liked for cruising and liveaboard situations because of the spacious deck area, which provides lots of space for unwinding and socializing.

The decision between monohulls and catamarans ultimately comes down to your sailing preferences, goals, and the kind of experience you’re looking for. Understanding the data enables you to make a decision that is in line with your sailing goals, regardless of whether you place a higher priority on performance, stability, comfort, or a combination of factors.

Sailboat Data Comparison – Famous Monohulls and Catamarans

Beneteau Oceanis 45: The Beneteau Oceanis 45 exhibits a well-balanced design that places an emphasis on both performance and comfort while sailing. It balances spaciousness and maneuverability with a reasonable LOA of 45 feet. With a 6.9-foot draft, it should perform well windward and be ideal for a variety of sailing conditions. A pleasant experience is guaranteed while on board because of the 14.9-foot beam, which enables a comfortable interior design. The SA/D ratio of 18 indicates a well-balanced sail area to displacement ratio, highlighting the boat’s adaptability to changing wind conditions.

Jeanneau Sun Odyssey 419: The Jeanneau Sun Odyssey 419 is the pinnacle of contemporary design and cruising comfort. It is nevertheless very maneuverable and has a generous amount of interior space despite having a somewhat reduced LOA of 41.6 feet. 5.8 feet of draft, which strikes a compromise between stability and accessibility to shallower seas, makes the boat well-suited for coastal and offshore sailing. A more streamlined design with a narrower beam of 13.9 feet is indicated, making it perfect for people who value ease of handling. A sailboat built for leisurely cruising with a SA/D ratio of 17 is likely, as it will provide a calm and comfortable experience on the water.

Lagoon 450: The Lagoon 450 is proof of the steadiness and roominess that catamarans are renowned for. The 45-foot LOA and opulent living quarters make it popular among liveaboard enthusiasts. It has a 4.3-foot shallow draft, which makes it easy to enter remote anchorages and bays. The large 25.9-foot beam ensures outstanding stability and a roomy deck area for socializing. It has the potential for exceptional speed and performance, especially when using the wind’s energy, as indicated by the high SA/D ratio of 24.

Leopard 44: The Leopard 44 caters to both cruising enthusiasts and sailors by striking a balance between performance and comfort. It offers a pleasing balance of internal spaciousness and maneuverability with a LOA of 42 feet. A balance is struck between stability and access to shallower waters by the 4.9 feet of draft. The large beam of 23.9 feet guarantees stability while underway and at anchor, improving the onboard experience.

Catamaran vs Monohull: Pros, Cons & Main Differences

By: B.J. Porter Editor

The choice of catamaran vs monohull ultimately comes down to preference. What’s critical for one buyer may mean little to another. If your partner refuses to set foot on a boat which heels, that’s a deal-breaker for a monohull. But if you’re passionate about classic looks and styling, your quest for beauty may override other considerations and rule out catamarans.

We can’t tell you whether a catamaran or a monohull is right for you. But we can help you with the pros and cons of each for your search.

The Strengths and Pros

No matter your choice of monohull or catamaran, there are safe, comfortable, and excellent sailing boats of both types. Neither has an exclusive lock on any strength, and both sail safely and comfortably. But there’s a different emphasis on how they do it. No matter what you are trying to do – sail fast, cruise the world, or just host a crowd at the dock, there are monohulls and catamarans that can work for any requirement.

Catamaran advantages

Space and comfort: Two hulls and a wide beam make a very stable platform with lots of volume in the saloon and cockpit. Most living space is above the waterline, with wonderful light and airflow. Cabins in the hulls offer better privacy and isolation, usually with standing headroom.

Straight line speed: Most catamarans are faster in straight-line sailing speed (1) that similar sized or even longer monohulls. Without a lead keel, they’re lighter, so more driving force from the sails converts to speed, and narrower hull forms may have less drag than wide hulls with deep keels. Some heavier cruising catamarans may not be faster, especially if they keep rig size small for ease of handling.

Stability : The beam of two hulls with a bridge deck leads to much higher stability and resistance to roll (2). Waves in an anchorage that induce violent roll in a monohull may make a catamaran bounce or bob. Under sail, catamarans do not heel appreciably even when powered up.

Twin engines. : With one engine in forward and balanced in reverse, most catamarans can spin in a circle in place and make sharp adjustments to the boat’s direction. If you have an engine failure, you also have a second engine, giving a safety edge when you can’t sail. 

Monohull advantages

Upwind sailing performance: While catamarans have the edge at straight-line speed, monohulls sail closer to the wind. When you’re racing or you have to sail upwind to get to the next island, this can get you there faster.

Sailing feel and responsiveness : The “feel” of sailing a monohull is much better. With a single hull, you’ll feel wind pressure and trim adjustments immediately for a more responsive helm and a better ability to sail to the wind.

Maneuvering under sail: Monohulls are quite nimble tacking and turning under sail, and there’s less risk of slow or missed tacks.

Righting Moment: The primary offshore safety argument for monohulls is their ability to right when capsized. The heavy keel keeps the boat deck up when sailing, and most monohulls will come back upright even after a complete capsize.

Cargo and Loading: A higher displacement boat with thousands of pounds of lead hung from the bottom isn’t going to be as affected by loading as a relatively light multihull.

Aesthetics: This is subjective, as many catamaran enthusiasts love how they look. Classic sailboat styling, with swept sleek looks, springy sheer lines, and all the “right” proportions are more common on monohulls.

Weaknesses and Cons

Like strengths, weaknesses are relative; just because one class has a strength doesn’t mean the other doesn’t. There are spacious monohulls and beautiful catamarans, just like there are cramped catamarans and unattractive monohulls. The differences have to be highlighted relative to each other, and the weaknesses of one are most apparent compared to the strengths of the other.

Catamaran Cons

Upwind performance: Cats don’t sail as close to the wind, but they make up for it by sailing faster off the wind. You’ll sail a less direct course upwind. Even if you get in at the same time, you’ll have to sail farther.

Less responsive sailing: Two hulls with two rudders and a very broad platform reduce the helm feel when sailing, cutting responsiveness sailing in shifting wind and wave conditions. It also makes tacking slower.

No-flip zone: It is very difficult, but not impossible, to flip a large catamaran (3). But if a catamaran capsizes, it will not flip back over by itself.

Large in marina/close quarters: You have two problems in marinas. Beamy cats are tough to maneuver in tight spaces because they’re big and visibility is tough over the hulls. And many marinas charge extra because the wide beam extends into the next slip. The good news is that twin engines make tight maneuvering easier.

Price point: Catamarans are more difficult to build and need more materials. This is directly reflected in the cost of the boats.

Monohull Cons

They are heavier: Every large monohull needs a keel for stability (4). They can not sail or stay upright without thousands of pounds of ballast, and this makes them heavier and slows them down. Tiny monohulls can use a centerboard or daggerboard for stability, but most boats big enough to sleep on need ballast.

Darker interiors : Most monohull living space is lower in the boat, where you can’t put enormous windows for light and circulation. It’s very hard to get space as bright and airy as catamaran saloons.

Less living space: With one hull and no bridge deck saloon, most monohulls feel cramped compared to spacious catamarans.

More prone to rolling motions : Only one hull makes monohulls susceptible to rolling in waves, and the movement can be quite uncomfortable.

Heeling: Tipping is just part of sailing monohulls upwind and is unavoidable. It can be reduced on some other points of sail, but not eliminated. Many people, especially non-sailors and new sailors, find this movement uncomfortable or distressing.

Catamarans vs Monohulls: Which is Better a Better Sailboat For You?

The question of whether to choose a monohull vessel or a catamaran is an eternal dispute between boat lovers. These arguments are usually based on one’s preferences and philosophy. In fact, the popularity of catamarans has grown significantly since their design facilitates many aspects of sailing. But, both mono-hulls and multi-hulls have their advantages and disadvantages. So, in this article, I’m going to list some details about both cats and monohulls so as to help you understand which one is better for you. Remember it all depends on what sort of experience you are looking for. Keep reading!

What is a Monohull?

In general, boats float due to the fact that they displace more water than they weigh. The hull is in “displacement mode” while a boat is stationary or moving slowly. That is, all of the upward forces that keep it afloat come from flotation, which is achieved by displacing water. With certain hulls, increasing the boat’s speed beyond a particular point causes the hull to lift up and skim along on top of the water. This is referred to as “planning.” Monohulls can be divided into two types; displacement and planing hulls.

Some hulls are only capable of moving at displacement speeds . This style of boat has generally slow speed, but it is incredibly efficient to operate. While moving, most have a smooth motion , though rolling (side-to-side movement) might be an issue. On the other hand, while on the sea, achieving fast speeds requires a hull that can readily transition onto a plane. Flat bottom surfaces from amidships aft, or from the middle to the back of the bottom, and a flat transom, or the back of the hull, are the main characteristics of a planing hull. Keep in mind that at a sharp angle, the transom must contact the bottom.

What is a Catamaran?

Nowadays, catamarans are becoming more and more popular. They’re particularly appealing to fishermen since they combine high-speed performance and a smooth rough-water ride with a solid angling platform. Catamarans have two primary disadvantages . Firstly, they require twin engines. Also, larger catamarans may be too broad to fit into standard marina docks. Another disadvantage is that there is less usable interior space than on a monohull of comparable length.

The two hulls of a catamaran are known as amas. These days, the popular phrase is “sponson,” but ama is still acceptable. Note that in comparison to its entire length, each ama is quite short. The narrow amas of a catamaran travel quickly through the water with little power. This allows for fast speeds even when the amas aren’t actively planning.

Trimarans on the other hand have three separate hulls. Sailboat designers have successfully employed this design to provide a large central hull for cabins. But, also for two outrigger amas for stability. The trimaran concept hasn’t been used much in powerboats, despite the fact that several “cathedral” hulls are related. Instead of three independent hulls, a cathedral design squishes them together to the point that they often share a similar planing surface near the transom.

Monohull or Catamaran? Let’s Take a Look at Their Pros and Cons

Catamarans are unsinkable because they are incredibly stable and have natural buoyancy. Yes, they can capsize in a major accident. But, being rescued while floating on the water’s surface is preferable to plunging to the bottom in a monohull. Furthermore, moving around on a flat deck is far safer than on an angled deck.

Classicists have long claimed that catamarans are not as safe as their keelboat counterparts. However, this remark is now regarded as archaic. Since it dates from the mid-nineteenth century when the majority of catamarans were made by amateurs. They could readily tip over even in calm weather, especially if one of their bodies became leakproof owing to damage. Sinking is extremely difficult, if not impossible, for a well-built modern catamaran. Modern structures are designed using computer simulations of various water conditions. Bear in mind that the maximum potential safe sail area is available to cruisers and charter possibilities in particular.

Monohulls , particularly sailboats, offer significantly stronger “self-righting” capabilities in the event of a worst-case knockdown situation. In a catamaran, once you’re upside down, you’re stuck there…And, who wants to be upside down in the middle of the ocean? Returning to an upright position gives you complete access to onboard safety equipment. This includes a liferaft, dinghy, flotation devices, EPIRBs, and strobe lights, which can save you if the boat sinks.

Generally, a catamaran’s high speed allows it to avoid adverse weather . While catamarans do not point as high into the wind as monohulls they are around 20% faster . Or, if they do, they create more leeway or slide sideways. This means that even if you sail upwind at a slightly broader angle to the wind than a monohull and cover a more distance, you will arrive at your destination sooner than a monohull.

A modern performance catamaran with daggerboards and strong sails may point as high as a monohull of comparable size. It will point similar to a comparable monohull but will sail far faster. This allows it to reach an upwind position far sooner than a monohull. However, it’s worth noting that the majority of production cats on the market are underpowered and have standard smaller sails. Many of these designs perform poorly in light breezes. Unless they’re equipped with larger headsails, a Code Zero, and a square-top mainsail.

While cats are more comfortable and safer in rough weather, we must admit that if the weather gets extremely terrible (60 knots of wind or more), it’s better to be on a monohull for survival reasons. For serious offshore single-handed sailing, I believe a monohull is superior since it is easier to hove-to in it. Bear in mind that when you’re in a cat during severe storms you won’t feel any danger, but it demands some nifty seamanship. And, keep in mind that even though a monohull can capsize in bad weather or even roll in a storm, they usually right themselves. A catamaran , on the other hand, is incapable of self-righting . However, the cat will usually stay afloat, providing a safe haven to wait out until aid arrives. Modern catamarans, on the other hand, are extremely difficult to capsize.

That being said, most catamarans can travel 200 to 250 miles per day, and with contemporary technology allowing one to control weather, it’s difficult not to deal with bad weather. In many circumstances, a faster boat is a safer boat because it can outrun heavy weather. A catamaran can avoid the worst weather and, at worst, put itself in the best position to avoid the brunt of a storm if there’s good weather routing information.

So, to sum up, cruising catamarans are quicker than monohulls, and sailing catamarans, depending on their angle, can sail at half the speed of the wind. It’s great to be on a boat that can swiftly attain high speeds and get you to your destination safely and on time. However, catamarans are faster because of their lower surface area , but their prices are generally higher than those of monohulls. Instead of fighting the elements, monohull designs operate in harmony with them . In addition, keep in mind that when sailing upwind, sailing catamarans are inefficient and tack slowly.

Fuel Consumption

Do you want to save money on gas? Then, in most cases, catamarans have less fuel consumption than monohull boats. Catamarans save a lot of gasoline since they have a less wetted surface area on their hulls. They can propel the boat with just one engine in weak winds. Also in flat water, and if the engines have the same number and horsepower. However, in heavier weather , where the higher efficiency of a monohull design provides less resistance , this is not the case.

Generally, catamarans have two fuel-burning engines, which can raise fuel expenses . However, because a catamaran is lighter on the water, it requires less energy to move. In a catamaran, you’ll use less fuel than you would in a monohull. Furthermore, in low-wind areas, catamarans might choose to use only one engine. This reduces the amount of fuel consumed by a catamaran even more . But, only calm waters are subject to these laws. A monohull is far more efficient than a catamaran in navigating waters with heavy waves and heavy winds. A monohull will consume less fuel than a catamaran in this situation.

The best feature of catamarans is that all of the rooms are on the same level. The four-cabin arrangement is common with sailing cats and is popular among charter companies. Owner versions usually feature three staterooms, with one hull serving as a big cabin for entertaining. Most catamarans have a big central living room with not one, but two narrow staircases leading down into the hulls—one on each side. It’s a little like living in a tube in the hulls. They’re too thin to accommodate walkaround double/queen berths like those found in monohulls. But, in case of an emergency, it would be impossible to communicate with someone in the opposite hull.

Obviously, a monohull has less space than a catamaran. This is due to the fact that a cat is broader and has a larger deck surface. It also has twice as many hulls as the other, giving you greater total space between them. People who want to host parties on their boats will appreciate the extra space. The catamaran is usually the party boat of choice at the docks, according to most boat owners. Even if you don’t like to host parties, the extra room might be useful for lounging on the balcony or tanning. The boat’s large open space also makes it simple to utilize as a fishing platform.

You also have more room for equipment like surfboards, rafts, and other equipment that can easily clutter a monohull’s deck. Even fishing from a catamaran can be easier because the deck allows for plenty of space between anglers. Owners of catamarans also have more room for carrying fresh water and installing generators and solar panels. A catamaran’s interior room is often larger, and in luxury catamarans, it’s easier to install heavy appliances like washers and dryers inside. These can be fitted to larger monohulls as well, though it will be more difficult than on a catamaran.

All of the extra space, on the other hand, means the catamaran owner has more room to maintain and clean. Furthermore, all of the other stuff that can be brought into the boat will add to its weight . And, as well all know, a heavier boat will consume more fuel and move at a slower speed.

Maneuverability

With their twin motors, catamarans are incredibly agile . On a catamaran, the engines are widely apart, making navigating more easier and more precise than on a monohull, unless the monohull incorporates a bow thruster. Most of the time, a bow thruster isn’t required because the engines are around 20 feet apart. When there’s no bow thruster (as do few monohulls) you have to rely on prop-walk and prop wash on the rudder. On her own axis, a contemporary catamaran can turn 360 degrees. A monohull would be unable to accomplish this while it has a larger turning circle.

A monohull under sail, on the other hand, is far more maneuverable and will tack much faster than a catamaran. But, the ease of movement under motor on a catamaran, especially in close quarters, is substantially superior. They also feature shallow drafts , allowing you to maneuver into areas that a monohull cannot, as well as anchor closer to shore . However, monohulls are more maneuverable as you don’t have to deal with two hulls. They can make sharper turns and travel through small channels and small areas easier than cats. In addition, their hull displacements lessen the negative impacts of crosswinds in confined spaces.

Anchoring and Docking

While docking a catamaran is simple, its big size makes it difficult to fit into a standard slip. However, with some skill and good planning, finding room should be no problem. You may even anchor or moor the boat and dock it with the dinghy, which is much easier than a monohull. However, keep in mind that in most cases docking, hauling, and slipping a monohull is significantly easier, takes up less room, and is far less expensive.

Moreover, docking a catamaran can be a challenging task. This is due to the fact that catamarans are frequently too wide to dock in the marina’s core regions. As a result, they must be docked at the far end of the dock. Therefore they have fewer docking options and raise the cost of docking. Owners of catamarans sailing through places where there aren’t many catamarans may find it difficult to find a dock at all. This is especially true in the northern Atlantic, where monohulls outnumber catamarans.

Keep in mind that one of the most significant advantages of a sailing multihull is its stability . Not only at sea, when heeling simply does not – or should not – occur to any significant extent, but also at anchor. It also greatly expands one’s anchorage options to include areas influenced by the swell. This is quite common in the Caribbean, where a slight shift in wind direction may make a previously flat, quiet anchorage intolerable in a monohull. In addition, its fairly shoal draught expands the options even more.

Catamarans have a large platform, making them ideal for relaxing at anchor without the rolling motion that monohulls are prone to in a swell. Many monohull sailors had to leave anchorages because of the uncomfortable anchoring. This is because large rollers or swells entering an anchorage can make the situation extremely uncomfortable and dangerous.

Also, a bridle is tied to both bows and down to the anchor chain on catamarans , resulting in a fairly secure position at anchor . In heavy winds, many monohulls tend to sail at anchor since the bow acted as a sail (due to the high freeboard). They sail in one direction until the chain snatches, then tack across and sail in the opposite direction, almost completely dislodging the anchor. The catamaran, on the other hand, is much more stable at anchor and does not sway as much.

Sailing Abilities

Most cruising multihulls won’t point like a monohull with a deeper keel upwind, and the motion may be rather unpleasant when sailing in rough weather. You must also keep a close eye on the sail area, but we’ll analyze this further below.

Moreover, catamarans are not suitable for racing and sailing sports. They can be fantastic for a holiday or even living aboard, but most racers would never buy one because of the stability. There is no sense of wind, waves, flying, or the boat itself on a catamaran. It’s quite tough to tell when it’s time to reef. While this can be done by feel on a monohull, there is specific instruction for catamarans as to what winds the sail area should be reduced.

When sailing to higher latitudes, like the North Atlantic, then a monohull would be a better solution than a catamaran. Residential areas are easy to heat and keep warm, and traditional metal may even melt thin ice. The contrary is true in the tropical zone, where huge catamaran salons would be unbeatable.

Monohulls can sail higher into the wind than most catamarans due to their keel. Daggerboards, which serve the same role as a keel and boost windward performance significantly, are common in some catamarans. However, daggerboards are not seen on 95 percent of cruising cats (those available for charter). Also, a monohull will be much easier to tack than a catamaran and glide lightly through the water. Moreover, in rougher seas, certain catamarans experience an annoying slapping of water on the bridge decks. A monohull responds to the helm more quickly than a multihull (in other words, they turn faster). This is due to the fact that most cruising cats have small “spade rudders” whose depth is dictated by the need for a modest draft. While with a keel, a monohull can have a more responsive rudder for its draft.

Monohull spreaders are 90 degrees to the mast, however, catamaran spreaders must be backswept. The reason for this is that a monohull has a backstay, and by combining it with the intermediates, you can achieve a lovely pre-bend in the mast. Keep in mind that the pre-bend is to flatten out the mainsail and allow for better performance.

Also, in order to pre-bend the mast on a catamaran without a backstay, you’ll have to utilize the backswept spreaders and diamonds. The reason I bring this up is that if you want to broad reach or run on a catamaran, you can’t let the mainsail out all the way because the backswept spreader tips could puncture the cloth. Because the spreaders on a monohull are at 90 degrees, you can let the main and boom out much wider, which is obviously more effective. This is one of the reasons why a catamaran should broad reach and tack downwind.

• Maintenance

Because catamarans have two of everything, there is a clear trade-off between maintenance costs, reliability, and redundancy. One of the most significant advantages of having two of everything is that you have a backup . As a result, even if one component fails, you can typically still utilize the boat, such as running on one engine while the other fails. While redundancy is fine, lower maintenance and repair costs are generally preferable. Although having two of everything provides you some redundancy, I doubt you’ll want to take the boat out if one of the two hulls “fails.” Of course, this means two hulls to clean and antifoul, double the engine maintenance, and so on , but having two of the important pieces of equipment, such as engines, outweighs the disadvantages.

Due to their weight-bearing, catamarans have minimal to no heeling and do not roll at anchor. With sudden gusts, heeling on a monohull can be dangerous and uncomfortable, not to mention seasickness. Again, the trade-off is a noisy ride and fast movement, which many people find uncomfortable in bad weather. However, the heeling action of a monohull sailboat offers stability, spills wind from the sails, and provides safety.

Catamarans, unlike monohulls, do not have ballast in their keels, therefore they rely on beam and buoyancy for stability. Typical cruising catamarans have a beam-to-length ratio of around 50%, while several modern designs exceed this figure. A 45-foot catamaran will be around 22 feet wide, offering a highly solid sailing platform. Monohulls, unlike catamarans, cannot overcome rolling and pitching because of their narrow beam and lead ballast.

Rolling and pitching on a monohull while underway is quite dangerous. But, walking around on the deck of a catamaran while underway is easier because the boat is considerably more stable and does not heel. Sail adjustments and reefing are also significantly easier and safer for the crew as a result of this. The risk of falling overboard on a catamaran is far lower than on a monohull because of the rolling and pitching motion.

Generally, buying a catamaran is substantially more expensive than a monohull. So, if you opt for a cat you should also consider your budget before even starting your research. Pre-owned monohulls, on the other hand, are extremely inexpensive to purchase due to a current supply that considerably outnumbers the demand.

Nowadays, catamarans are in high demand , and they normally keep their worth far better and longer than other types of boats. And that’s why the market is currently centered to manufacture lots of them. Bear in mind that looking for a catamaran under $250,000 your options will be limited, and finding a catamaran under $100,000 is nearly difficult. Unless you opt with older boats like the Prouts or the less priced Geminis, a monohull is your best bet in this instance.

The cost of a cat rises if you need at least two of everything. But, keep in mind that due to their popularity, catamarans have a high resale value and a low depreciation rate , and they normally sell faster than monohulls. Due to the fact that most catamarans are not made in the United States, delivery expenses must be considered when purchasing the boat. Multihulls are becoming more popular, and as a result of the increased demand, they command greater prices in both the new and brokerage markets. Lastly, when considering a purchase, keep in mind that maintenance costs are substantially higher than on a monohull.

Catamarans vs Monohulls – The Bottom Line

So, this is it! We’ve come to the end of this highly discussed topic among sailors. Obviously, everything would be determined by two basic factors: personal preferences and budget considerations. Both monohulls and multihulls have their pros and cons and it’s totally up to you to decide which one suits you best. Because the two types of vessels provide such a different experience, it is highly recommended that you rent and test each one before purchasing to compare everything. In any event, it’s reasonable to say that a catamaran is an excellent choice for a charter, if not for purchase. Despite its high price, it provides comfort, space, and stability but you have a better overall sailing experience with a monohull. So, I hope that this article will help you make the right choice according to your needs. I wish you good luck with your research!

Catamaran Vs Monohull

Last Updated by

Daniel Wade

August 30, 2022

Monohulls and traditional sailboats, once ubiquitous, are giving way to modern catamarans. But how do these designs differ?

Monohulls have a single hull, and catamarans have two hulls side-by-side. Catamarans are faster than monohulls of the same length and displacement, but monohulls are stronger and more spacious. Monohulls are also cheaper and easier to build than multi-hulls.

In this article, we’ll cover the differences between catamarans and monohulls, along with the benefits and drawbacks of each design. We’ll also cover the sailing characteristics of each and why catamarans so easily outrun equivalently-sized monohulls.

We sourced the information used in this article from trusted sailboat design resources, along with manufacturer specifications and boat market analysis.

Table of contents

‍ What is a Catamaran?

Catamarans are a kind of multi-hull sailboat with two hulls joined together. They are often short and wide, resembling a square or rectangle from above.

Catamarans are colloquially distinct from outriggers, which are double-hulled vessels with one large primary hull and a small outboard stabilizing hull.

Catamarans usually have hulls that mirror each other, both in size and arrangement. Sometimes, the interior layouts are mirrored, too—but this varies between designs and manufacturers. Catamaran hulls are narrower and taller than most monohull designs of equal lengths.

Catamarans have limited commercial and military utility, as these applications favor space and ease-of-construction over handling characteristics. That said, there are some commercial uses for catamaran designs—most commonly passenger and car ferries.

What is a Monohull Sailboat?

A monohull is probably what you traditionally think of as a boat. Monohulls are longer than they are wide. It features a single hull—it’s that simple. Sailing monohull designs have evolved over the centuries into many distinct types, usually distinguished by keel type.

Monohulls come in many shapes and sizes . For example, sailing monohulls designed for offshore use have long keels that sometimes extend much further below the waterline than the freeboard and cabin extend above it.

Monohull sailboats are also designed for other purposes, such as inland sailing and racing. These vessels have more contemporary characteristics, such as rounded shallow ‘canoe’ bottoms, V-bottoms, and fin keels.

Monohulls aren’t just sailboats. Virtually every cargo and container ship, warship, and many passenger ships are monohulls due to their strength, ease of construction, and high cargo capacity.

Are Monohull Sailboats More Common?

Monohulls are more common in every application, though multi-hulls are becoming more common for ferries. Monohulls have numerous benefits over multi-hulls, and these benefits only increase with scale.

Monohulls are easy to construct. They’re also cheap. Large monohull ships, such as container ships, can be built with very little material and effort. This is because the vast majority of the length of a monohull is just a box, with a bow and stern welded onto the end.

Sailboat construction is more intricate, but the costs are still lower. Plus, monohull designs are robust, and cabin space is plentiful. There’s a lot more study in the field of monohull design, which was the universal truth until somewhat recently.

But all in all, the reason why monohull sailboats are more common is that they work just fine. Most sailboat owners aren’t interested in breaking speed records or hosting dozens of people aboard their boats. As a result, a standard, simple, and easy-to-control monohull are more than sufficient.

Are Catamarans Faster than Monohulls?

Catamarans are most certainly faster than monohulls. This is almost always the case. Even the fastest production monohulls can’t hold a candle to the average cruising catamaran.

But why is this the case? Aren’t catamarans restricted by the same hydrodynamic forces as monohulls? As it turns out, they aren’t. This has to do with the unusual way hull waves impact speed.

Hull Speed Limitations

Monohull speed is limited by something called hull speed. Hull speed is determined using a formula that calculates the maximum speed a displacement hull can travel under normal power and conditions.

When a displacement hull moves through the water, it kicks up a set of waves at the bow and stern. These waves travel along the side of the vessel and create drag, which slows down the boat. Normally, the power of the wind can overcome this drag—but only to a point.

At a certain speed, the waves kicked up by the bow will sync with the waves kicked up at the stern and begin ‘working together’ against the boat. The speed at which this occurs is the hull speed, which is calculated from the length of the boat.

Hull speed limitations for monohulls aren’t universally true all the time. Some vessels exceed it, and some don’t—but the number is a useful estimate of the limitations of monohull designs. Modern monohulls with clever hull shapes can defeat hull speed calculations.

Do Hull Speed Limitations Apply to Catamarans?

Surprisingly no—hull speed calculations don’t work for catamarans. This is because, for one, the hulls are shaped differently. Alone, catamaran hulls wouldn’t float correctly. But together, they create different hydrodynamic effects and cancel out the effects of hull speed.

This means that catamarans can easily exceed the speeds of even the fastest monohulls of equal length—and sometimes beat them by a margin of 50% or more. It’s not unheard of for 40-foot catamarans to exceed 20 knots, whereas 40-foot monohulls rarely get past 10.

Are Catamarans More Comfortable than Monohulls?

Catamarans can be much more comfortable than equivalently-sized monohulls—up to a point. This is because catamarans engage in ‘wave piercing’ and have a wider and more stable footprint on the water.

Catamaran hulls, when properly designed, can slice through parts of a wave instead of riding over every peak and trough. This effectively reduces the height of the weight, which reduces the amount the boat rolls.

Additionally, the wide footprint of a catamaran allows some waves to simply pass right under it, keeping the boat level for longer durations. Catamarans also don’t heel under sail—instead, they plane slightly, raising the bows out of the water and reducing bumps.

Monohull Benefits

Monohulls are proven in all conditions. A well-designed displacement monohull sailboat can ride out the strongest storms, and monohull workboats can support enormous loads and move them efficiently. They can be fast, comfortable, and also easy to sail (even for beginners).

Monohulls are cheap to build and forgiving, as precision doesn’t have to be microscopic to get them to sail right. They’re robust and strong, featuring a naturally stress-resistant hull shape. They’re also easy to modify and aren’t required to meet as strict of dimensional ratios to operate.

With a monohull sailboat, you have a lot of interior room to work with. This means that monohulls are available in numerous cabin layouts and are just as easy to modify as they are to build. Monohulls often have a center of gravity at or below the waterline, which enhances stability at steep heel angles.

On the water, displacement monohulls can weather extreme conditions with ease. They lack the initial stability of multi-hulls, but they can recover from knockdowns on their own, and they’re very difficult to push past their rollover point.

Why do Catamarans Cost More than Monohulls?

Catamarans cost more than monohulls because they’re more expensive to build, more complex to engineer, and require more material. This isn’t always the case, but the design of catamarans requires much more careful engineering and strength-of-materials analysis than comparatively simple monohulls.

There are several critical structural points on catamarans that monohulls lack. In fact, the very shape of a monohull is physically strong—so it has inherent durability. Catamaran hulls must be joined in the middle, and the mast must have a strong point far from the inherently sturdy hulls.

This requires stronger materials and more care during design or construction. This is why catamarans remain a premium part of the sailboat market and why they still aren’t the most popular sailboats despite their numerous performance and comfort benefits.

Catamaran Cabin Layout

Catamaran cabins are split between the two hulls, and there’s usually a large pilothouse in the center. Pilothouse catamarans can be quite spacious, primarily due to the large space between the hulls.

The pilothouse is usually where kitchen and sitting areas are located, along with cockpit access and the controls of the sailboat. The mast is also located in this area.

Catamaran cabins sometimes mirror each other. For example, each hull may contain two identical bedroom/bathroom combos, while the center console area contains the kitchen and living spaces.

The two identical hulls sometimes make for unusual design decisions (such as small catamarans with four master bedrooms), but owners say this gives their passengers a much better experience than a monohull cabin.

Monohull Cabin Layout

Monohull cabins, with the exception of split-cabin sailboats with a center cockpit, have only one large interior space to work with. It’s usually much wider than catamarans of equal length.

Monohull cabins are usually accessible from the bow (via a flush deck hatch) and the stern via a traditional companionway. They run the span of the hull between the bow and the cockpit and sometimes include spare berths under the cockpit seats.

These spare berths are often used as convenient sea cabins, as they offer quick access to controls in case of an emergency. Catamarans often have convertible berths in the center console for the same reason.

Monohull cabins are traditional and include everything that catamaran cabins do—albeit with slightly less room overall. That said, individual spaces are often much wider, and facilities are more appropriate.

Catamarans vs. Monohulls

Which is better, a monohull or a catamaran.

This question gets asked a lot in sailing. Especially if you are looking to take your friends or family out for the week: which will be better, a catamaran (aka cat) or monohull (aka mono)? The short answer is it depends what sort of experience you are looking for. Let's explore this further.

Tell me more about monohulls and catamarans.

Monohulls are boats that have one hull. They are the classic sailing yachts that you see old black & white photos of, racing off Newport or Cowes.

Catamarans on the other hand have two hulls. They tend to be newer, and are said to be less traditional, although some of the earliest sailing boats ever developed may well have been catamarans.

Things to consider

Now that we understand the difference between catamarans and monohulls, let's look at attributes that are important in sailing. Once we have explained these, we can look at how each boat-type deals with them:

For obvious reasons, you want to have a stable boat. Monohulls are a bit like a roly-poly doll, where when pushed over, they tend to right themselves. That is unless they reach what is termed the "angle of vanishing stability" or AVS. Catamarans deal with stability in a different way.

Catamarans tend to be much more stable in most conditions, but should they capsize, they quickly become stable, albeit upside down.

Nevertheless capsizing is such a rare occurrence that "stability" here really means comfort when sailing.

Living area

Your boat needs to strike a balance between sailing well and being comfortable to spend time in. The layout of the boat is important in this regard: what level it is on, how large it is, and how square the space is.

The draft of a boat is how far in the water it goes. "How much does she draw" means "what is the minimum depth of water that this boat needs so she doesn't go aground". Monohulls by definition require a keel, a heavy piece of iron or lead that goes deep into the water. Catamarans do not require this, and therefore tend to have a "shallower draft".

Maneuverability

Being able to easily maneuver your boat is clearly an advantage in tight situations, such as when docking in a crowded marina. Both monohulls and catamarans have their pros and cons here, which will be explained further below.

Maneuverability, image thanks Cruising World (cruisingworld.com)

The speed of a sailboat is not as simple as for a motorboat. The angle of the wind has a large effect on the speed of a sailboat. Some boats can sail faster when close to the wind - monohulls normally fall into this category - while others can sail very fast when the wind is on their side (aka a beam reach) - catamarans usually like this sort of "reaching" sailing.

Having natural light and a decent view can make the living space much more comfortable. With monohulls, most of the living space is "down below" whereas for catamarans, most of the living area happens "up" in the saloon which is located between and above the two hulls. This creates two different environments. One person's "cozy" is another person's "claustrophobic". Just the same, one person's "light and open atmosphere" is another person's "soulless". So there is a fair degree of taste to this particular aspect.

"Feeling Sailing"

By this we mean the feel of the boat responding to the wind as she slices through the water. Some people sail for this feeling, while others simply sail as an ecological, efficient way to move from A to B. Monohulls and catamarans offer very different visceral experiences here.

In breaking down the pros and cons of monohulls and catamarans, we found that a pro for one was a con for another. With that in mind, we think it is more helpful to list the pros of each, so you only read it once. Here goes:

8 Pros to Catamarans

1. catamarans are inherently stable..

Two hulls provides a wide base, which means in most sea states, less "bobbing". Every now and then, when the space between wave tops is a certain distance, the cat can lurch. But this is more the exception than the rule.

Here are some more pros of stability:

• Stability is a big factor for families with young children or seniors. It suits "non-sailors" in the group;
• Stability is very helpful for those prone to sea sickness (although scopolamine patches are probably still required if someone is very susceptible to getting sea sick);
• Stability means things are more comfortable at anchor, and for cooking;
• Because cats don’t heel over nearly as much, storage and stowing of provisions and household items is much easier.

2. Catamarans have more space.

Catamarans generally have much more living space in the main salon, galley and cockpit, and in the cabins. This can allow for greater privacy when chartering with friends or children, as the two sleeping areas (one in each hull) are separated by the living area. Here are some more pros of space:

• More space on a catamaran for preparing food, which means the cooking experience tends to be less a balancing act, and more like the kitchen at home;
• More space on a catamaran for storing things, which means people are not tripping over them throughout the trip.
• The space on a catamaran is square-shaped, akin to an apartment, as opposed to a monohull which tends to be more rectangular.

3. Catamaran living space is above the water line.

On a monohull, almost all living space on a is at least partially below the water line, which limits light and view, and can lead to claustrophobia in some. Catamarans on the other hand, sit above the water line. In addition:

• Ventilation in the main saloon area on catamarans is generally excellent, given their above-water design.
• Most of the living quarters are also above the water line, which allows for more light and a better view, as well as better circulation of air.

4. Catamarans can venture into shallower areas.

The lack of keel on a catamaran results in a shallower draft, allowing to anchor in shallower water, which is especially valuable around reefs in the tropics.

5. Catamarans can turn on a dime.

Because catamarans have two engines and two rudders, maneuverability in tight spaces is improved, with most cats being able to turn 360º within the length of the boat.

6. Catamarans (usually) sail faster.

Without the need for a heavy keel, catamarans are lighter than an equivalent monohull. That, plus the fact that they keep their sails perpendicular to the wind, means they sail faster than monohulls, especially on a run or broad reach.

7. Catamarans are harder to sink.

Without the need for a lead-weighted keel, catamarans are not just lighter and faster, they are also harder to sink. Monohulls have been known to "lose their keel", by hitting something such as a semi-submerged container or even a whale. When this happens, the boat will tend to sink within minutes. Catamarans do not have a keel to lose, which means in this (admittedly very rare, blue-water) event, catamarans come out trumps.

8. Catamarans allow spooning.

Most catamarans have a trampoline or net at the front. This allows for spacious and comfortable cuddling under the stars - not to be underrated.

Monohull Pros

1. monohulls look great..

You can’t beat a monohull sailboat for good looks. Classic, sleek, beautiful, there is a timeless beauty to monohull sailboats.

Catamarans on the other hand have a “non-traditional” aesthetic that some consider to be a little harsher on the eyes. Let's face it, many are downright ugly.

2. Monohulls are a romantic, evolving tradition.

Do you love the old photos of well-dressed people sailing their immaculate wooden monohulls in beautiful surroundings? If you answer yes to this question, take a good look at monohulls. That romance and tradition is still there.

3. Monohulls give you more options.

Due to the sheer volume of monohulls made over the last century, there are many more options for a boat that meets your individual lifestyle, personal aesthetic, or budget.

4. Monohulls carry a lower cost.

• Monohulls take up half the space at a marina than catamarans, and therefore generally cost you half as much.
• Monohulls are more readily available used in good shape, and cost less to charter for equal sleeping capacity.

5. Monohulls sail better upwind.

Due to their keel, monohulls can sail higher into the wind than most catamarans. Some of the more exotic catamarans have daggerboards which serve the same purpose as a keel, and therefore improve windward performance substantially. However 95% of cruising cats (ie. those you can charter) do not have daggerboards. Furthermore:

• A monohull will be far easier than a catamaran to tack.
• Monohulls slice through the water effortlessly. On some catamarans you get an irritating slapping of water on the bridge decks in rougher seas.
• A monohull is generally faster to respond to the helm (in other words, they turn faster). This is because most cruising cats have little "spade rudders", with their depth dictated by the need to have a shallow draft. Whereas with a keel, a monohull can have a far deeper (read: more responsive) rudder for its draft.

6. Monohulls give you more feedback when sailing.

This factor (and lower cost) is why most sail training happens on monohulls. If you have too much sail out for the wind, your overpowered monohull will heel over and become a pain to sail, before anything breaks. 

On a catamaran you get less feedback at the wheel, which if you are not being very attentive can get you into trouble in big winds.

Then there is the visceral joy of "feeling sailing". A monohull will heel (meaning it is designed to tip over anywhere from 10º to say 50º) whereas a catamaran won't. While their increased heeling can be a performance disadvantage, it can also be an advantage as it is a lot of fun. 

7. Tacking is easier on a monohull.

While they can accelerate faster, catamarans also decelerate much quicker, and as such can have a harder time maintaining momentum through a tack. It depends what sort of sailing you are after. If it is about enjoying being outside, and not so much about the sailing itself, then a catamaran is fine. But if you are out there sailing for sailing's sake, then you will probably find more enjoyment on a monohull.

8. Monohulls tend to swing less at anchor.

While they may rock more in a side to side motion than their equivalent catamaran, monohulls tend to swing less at anchor.

Conclusions

The above shows that there are no clear winners to the Catamaran vs. Monohull debate. At Sailing Virgins we teach and cruise on both monohulls and catamarans. If you have to make a decision yourself it really comes down to:

• How much hard-core sailing you (and your crew) intend to do;
• What your budget is;
• How much space you need;
• How shallow the bays are that you would like to visit.

We hope that helps your decision making.

Sailing Catamaran vs. Sailing Monohull Yacht

Are you considering sailing on a catamaran or a monohull? Read this article to explore the pros and cons and find the answers you are looking for. If you have not yet tried sailing on a catamaran but are interested, the following list of differences between monohulls and catamarans may help you decide which one to charter.

Catamaran charters have become very popular due to several essential characteristics. The great buoyancy enables the entire boat to act as sort of a raft. Catamarans have great manoeuvrability since most catamarans have twin engines, so they can be more comfortable to dock than a single-engine monohull. Modern catamarans can do a 360 turn in their length. 

In contrast, monohulls might provide you with more of a “real sailing” feeling , more thrills and exciting moments. Adrenalin junkies would love hanging on the side of a sailing yacht , while it is heeling under 25° under full sails.

Monohulls are offering a specific sailing charm for real sailing enthusiasts.

But don’t get the wrong impression, monohulls are not just for hard-core sailors. They have a comfortable salon area, spacious cabins, and areas for sunbathing and other activities. On the other hand, charter clients who tend to sail during the peak of the season are putting more value on spaciousness, comfort, and stability than the ones who are sailing during pre/post-season when sailing conditions are more favourable. It could be that the popularity of multihulls lies in those facts.

Spaciousness & Comfort

First on the list of catamaran vs monohull characteristics is spaciousness , in favour of the catamaran. More cabins, a larger salon area and more extensive areas for sunbathing than on a monohull of the same length. If you prefer comfort and more space, multihulls are your go-to yachts for sailing vacations . 

Large net areas on the bow of a boat provide you with a unique feeling while lying on them during your sailing trip or when soaking up the sun while anchored in a lovely bay. With all that additional width, cockpit areas on multihulls are offering massive amounts of space making them ideal for a large family meal or an exclusive party area. There are also owner’s versions of the multihulls where one whole hull is dedicated to the owner, resulting in an impressive size suite on the boat, which will satisfy the most demanding ones.

Next on the catamaran vs. monohull list of pros and cons is the fact that multi-hulls are offering more stability, which is ideal for families with kids - especially while walking around the yacht since all areas are more extensive than on a monohull yacht. There is no heeling under a 25° angle when the sails are up, so boat guests can enjoy and even prepare their food and drinks while sailing.

Most of the multihulls have a separate flybridge with nice, shaded areas for enjoying the ride or a drink, and it can also convert into sunbathing areas. The separated flybridge also means a complete separation of skippers that provides maximum privacy for yacht guests or owners.

A separated skipper cabin could be found on almost every multihull. On the larger ones, those skipper cabins have full equipment (toilet, sink, shower, etc.), leading toward complete separation of a crew and yacht guests in case that is necessary.

Pounding and Slapping

Multihulls such as catamarans and trimarans are deriving their popularity from the fact that most of them are created for extracting maximum pleasure out of your vacation at sea. However, there is one advantage most monohulls have compared to catamarans, and that is when underway is that they do not pound or slap . Catamarans with low bridge deck clearance tend to hit and slap on the undercarriage in lumpy seas when sailing upwind. This may sometimes feel as though the boat is getting beaten to pieces.

Speed Difference

Catamarans are in most sailing conditions faster than monohulls, because of their hulls which are less immersed in the water and have a smaller area in the water to create drag. Multihulls are unusually fast when sailing downwind for the reasons just mentioned above. When sailing downwind they are faster than monohulls, but when they are cruising windward, close-hauling monohulls are usually faster.

Manoeuvring & Docking

When talking about catamarans vs. monohulls , when it comes to manoeuvring and docking; monohull sailing yachts are propelled just by one engine which can combine with a bow thruster on the front. The bow thruster is a small electric engine on the bow of the yacht enabling it to move bow sideways by the press of a button, providing additional skipper security and making it easier to manoeuvre in tight spaces.

Two engines propel multihulls. Two engines can be significant in case of emergency when one of the engines fails, but they are also great for manoeuvring in tight spaces. Two engines are enabling the skipper to rotate the yacht for practically 360 degrees at one point, meaning very little manoeuvring space is necessary for a large and wide yacht to dock.

Catamaran vs. Monohull Yacht – the Final Verdict

In the end, we are back to personal preferences and finance, especially when choosing a catamaran vs. a monohull . Catamarans are more expensive to buy/rent and to moor/dock, but they offer a lot for their price. They provide an extraordinary sailing sensation filled with luxury, for individuals and families looking to spend their vacation at sea, sailing while wining, dining and enjoying the sun. We have to make it clear that the sailing sensations of mono and multihulls are also entirely different. For adventurous individuals heeling under 45 degrees would be ideal, but for ones who would like to have a nice meal and sunbathe during sailing, multihulls would be perfect.

Evolved from Safehaven’s 75-foot XVS20 monohull launched in 2018, Kowalski used his expertise in building commercial, work-boat power catamarans to design the twin-hulled T-2000 Voyager to offer speed with stability.

“The stability in beam seas is what’s key here,” he says. “While we were out recently in a Force 8 with 40-plus knot winds and 12-foot seas, we were able to stop and leave the boat to drift while we retrieved a drone. It just took the waves on the beam with ease. In a monohull, it would have been rolling so badly you couldn’t have stood on the deck.”

Then there’s the sheer velocity that comes with twin, scalpel-thin hulls slicing through waves. With the T-2000’s pair of 1,550 hp MAN V12 diesels driving France Helices SD5 surface drives, the Safehaven can hit a top speed of 57 mph. 

“It’s just the most amazing sight, standing on the stern, watching these huge roostertails behind,” Kowalski adds. “We’ve also incorporated retracting swim platforms so you can see the props spinning on the surface, plus valved exhausts that switch between silenced and straight-through. The noise from those V12s is sensational.”

His hull No. 1 demonstrator boat has all-diamond-quilted marine leather, well-finished cabinetry, colored LED lighting, and below-deck accommodations for six in three cabins. Hull No. 2—already sold and due for completion in the next 18 months—will up the luxury factor.

“It’s going to a client in the Middle East who plans to use it for just himself and his wife,” says Kowalski. The client has specified a full-width owner’s suite with a central, king-size bed and oversized his-and-hers bathrooms and closets in each hull. “He also wants to go fast— very fast,” Kowalski continues. “So we’ll install twin 2,000 hp MAN V12s, again with surface drives, and a central hydrofoil to reduce drag. The plan is for it to hit a top speed in excess of 69 mph.”

The new T-2000 is also designed to go the distance. With the 2,900-gallon tanks, it has a range of more than 1,000 nautical miles at 34.5 mph, and 1,700 nautical miles at 18 mph. Throttle back to 12 mph and range increases to 3,000-plus nautical miles.

Much of this is down to the yacht’s symmetrical, semi-wave-piercing hulls, made of a carbon-fiber-composite construction, with inverted lower bow sections and a double-chine arrangement that projects spray clear of the boat. The hydrofoil in mid position also means that, at speed in calmish seas, the T-2000 rides with half its hull length out of the water.

To eliminate waves slamming into the bridge deck windshield, Kowalski moved the pilothouse farther back. It also makes for a sleeker profile, giving the T-2000 the look of a single-hull sportsyacht.

The entire helm area gets flooded with light courtesy of the four-panel, angled windshield and quartet of fixed skylights above. To see the boat’s hydrofoil in action, the bridge has a glass panel in the floor that’s also designed for viewing marine life below at night. Most of the windows have half-inch-thick toughened panels to shrug off cascading water. 

In finer weather than typically found on coastal Ireland, the T-2000 has a small flybridge with a helm station and sun-lounge area up top, plus a covered stern cockpit with sofas and table for alfresco dining.

This storm-tested, metallic-red demonstrator is available for around $3.35 million.

Video shows moments before superyacht went down in storm off Sicily

Newly released video captures a luxury superyacht being battered by a violent storm before it suddenly sank off Sicily with 22 people aboard Monday.

The grainy images obtained by NBC News and other outlets were recorded on closed-circuit television not far from where the Bayesian was anchored, about a half-mile from the port of Porticello, on Sicily’s northern coast .

The yacht's 250-foot mast, illuminated with lights and lashed by the storm, appears to bend to one side before it finally disappears and is replaced by darkness.

The speed with which a yacht built to handle the roughest seas capsized stunned maritime experts.  

“I can’t remember the last time I read about a vessel going down quickly like that, you know, completely capsizing and going down that quickly, a vessel of that nature, a yacht of that size,” said Stephen Richter of SAR Marine Consulting.

British tech tycoon Mike Lynch and five of the 22 other people who were aboard the 184-foot vessel remain unaccounted for and are believed to be trapped in the Bayesian’s hull, nearly 170 feet underwater.

Officials confirmed Monday that at least one person, the ship’s cook, had died.  

Superyachts like the Bayesian, which had been available for charters at a rate of $215,000 a week, are designed to stay afloat even as they are taking on water to give the people aboard a chance to escape, Richter said. 

“Boats of this size, they’re taking passengers on an excursion or a holiday,” Richter said. “They are not going to put them in situations where it may be dangerous or it may be uncomfortable, so this storm that popped up was obviously an anomaly. These vessels that carry passengers, they’re typically very well-maintained, very well-appointed.”

Built by Italian shipbuilder Perini Navi in 2008, the U.K.-registered Bayesian could carry 12 guests and a crew of up to 10, according to online specialist yacht sites. Its nearly 250-foot mast is the tallest aluminum sailing mast in the world, according to CharterWorld Luxury Yacht Charters. 

On Tuesday, Italian rescue workers resumed the search for Lynch and the five other passengers still missing: Lynch’s 18-year-old daughter, Hannah; Morgan Stanley International Chairman Jonathan Bloomer and his wife; and Clifford Chance lawyer Chris Morvillo and his wife.

“The fear is that the bodies got trapped inside the vessel,” Salvatore Cocina, the head of civil protection in Sicily, told Reuters .

The Bayesian is owned by a firm linked to Lynch’s wife, Angela Bacares, who was one of the 15 people rescued Monday after it capsized.

“It’s extremely rare for a boat of this size to sink,” Richter said.

What’s not rare is the kind of storm that sank it , said Simon Boxall, senior lecturer in oceanography at Britain’s University of Southampton.

“People assume the Mediterranean is this rather calm and passive place that never gets storms and always blue skies,” Boxall said. “In fact, you get some quite horrendous storms that are not uncommon at this time of year.”

The president of Italy’s meteorological society has said Monday’s violent storm may have involved a waterspout, essentially a tornado over water, or a downburst, which occurs more frequently but doesn’t involve the rotation of the air.

Luca Mercalli, president of the Italian Meteorology Society, also said recent temperatures may have been a factor. 

“The sea surface temperature around Sicily was around 30 degrees Celsius [86 Fahrenheit], which is almost 3 degrees more than normal,” Mercalli told Reuters. “This creates an enormous source of energy that contributes to these storms.”

The Mediterranean sailing vacation was designed to be a celebration for Lynch, who two months ago was acquitted by a San Francisco jury of fraud charges stemming from the 2011 sale of his software company Autonomy to Hewlett-Packard for $11 billion.

Prosecutors alleged that Lynch, dubbed “Britain’s Bill Gates,” and Autonomy’s vice president for finance, Stephen Chamberlain, had padded the firm’s finances ahead of the sale. Lynch’s lawyers argued that HP was so eager to acquire Autonomy that it failed to adequately check the books .

Lynch had taken Morvill, who was one of his defense attorneys, on the luxury trip. 

Chamberlain was not on the Bayesian.

In what appears to be a tragic coincidence, a car struck and killed Chamberlain on Saturday as he was jogging in a village about 68 miles north of London, local police said.

“Steve fought successfully to clear his good name at trial earlier this year, and his good name now lives on through his wonderful family,” Chamberlain’s lawyer, Gary Lincenberg, said in a statement .
