How Much Do Boats Weigh? (Ultimate Data Chart)

The weight of a boat can vary a lot mostly depending on the length of the boat and the materials used for the boat. There are also many other factors such as size/amount of engines, size of the fuel tank, amount of gear on board, size of the cabin, and much more.

However, if we generalize based on length: small boats that are 17-22 feet weigh around 1,600-3,200 pounds. Boats 23-27 feet weigh around 3,600-4,800 pounds. Medium-sized boats 28-35 feet weigh around 5,800-13,500 pounds. And large boats 36-45 feet weigh around 15,500-29,000 pounds.

These calculations were found by taking many examples of boats within each boat category. However, If you want a more precise answer that considers lengths and material, continue reading to the “ Boat and trailer weight based on the type and length of a boat ” sub-heading.

It’s important to note that boats made from aluminum tend to be around 300-1,500 pounds lighter than similarly sized fiberglass boats.

Knowing boat weight terms

Before getting specific with all the different boat types, knowing these terms will help you understand the data better.

If you’ve ever tried finding the weight of a boat, you’ll notice that manufacturers use a lot of different wordings. These may include dry weight, wet weight, curb weight, package weight, gross trailer weight, actual boat weight, and more.

Understanding the difference between these is important, especially if you plan on reading the rest of the article. So let’s get into it:

Dry weight is the most common weight statistic you will find on a manufacturer’s website that states the weight of their boats. It means the weight of a boat without any engines, fuel, water, or accessories. In other words, the weight of a boat straight from the factory.

Some manufacturers may include engines in dry weight, but if they do so, they will usually tell you.

Unfortunately, this number isn’t the number boat owners need; however, it’s usually the only number provided. I usually assume that the wet weight of a boat is around 300-1,500+ pounds more, mostly depending on the amount/size of the engines and the size of the fuel tank.

Wet weight/curb weight

Wet weight, also known as curb weight, is the weight of a boat including engines, accessories, fuel, oil, and any other liquids. It does not include the weight of passengers or cargo.

This is one of the most important terms you’ll need to know for your boat as it will help you find your needed vehicle towing capacity, boat lift weight capacity, and other miscellanies things.

Package weight/gross trailer weight

Package weight, also known as gross trailer weight (GTW), is the wet weight of your boat plus the weight of your trailer. This is the weight you need to know for towing.

Most trailers weigh around 600 pounds for small 17′ boats to 1,900 pounds for larger 26′ boats. Most boats over 30′ are not trailerable unless you opt for an oversized load.

Actual boat weight

Actual boat weight means the wet weight of your boat plus any equipment, people, or cargo on board your boat. If a lot of people are on board or if you have a lot of heavy fishing equipment, it will significantly raise the weight of your boat.

Factors that go into how much a boat weighs

Besides the size of a boat, there are some other factors that go into how much it will weigh including:

• Material used
• Size of engine(s)
• Amount of equipment
• Amount of batteries
• Size of the fuel tank
• Amount of fuel in the fuel tank
• Amount of water within the boat
• Amount of gear you have on-board

Most of these are accounted for in the averages I’ve provided, but if you are trying to estimate the weight of your boat and you know you have an abnormally heavy or high quantity of these things, make sure to account for it.

Boat and trailer weight based on the type and length of a boat

There are many different boat types, all of which have different weights. Below I’ve listed the weights, trailer weights, and gross trailer weights (wet weight of boat plus trailer weight) of many different boat types. Click on the boat type below to be directed to which one you want to see.

There are two popular materials used to build bass boats, fiberglass and aluminum. Fiberglass is much heavier than aluminum, so I decided to split up the two in order to give more precise averages. So:

On average, fiberglass bass boats weigh around 1,400-2,200 pounds. Aluminum bass boats weigh around 700-2,000 pounds. Their gear, fuel, and engines generally add another 400-700 pounds and their trailers generally weigh around 500-1,200 pounds.

On average, ski boats weigh around 3,100 pounds. Their gear and fuel generally add another 250-600 pounds and their trailers generally weigh around 1,100-1,900 pounds.

There aren’t many true ski boats on the market anymore as they are being taken over by wake boats, however here are the weights of the top 3 on the market.

Related article: How Much Do Ski Boats Weigh? (17+ Examples)

On average, wake ski boats weigh around 4,000-6,700 pounds. Their gear and fuel generally add another 250-600 pounds, and their trailers weigh around 1100-1,900 pounds.

On average, aluminum deep V fishing boats weigh around 1,000 to 2,100 pounds. Their engines, gear, and fuel generally add another 350-700 pounds, and their trailers weigh around 500-1,100 pounds. Fiberglass equivalents generally weigh 400 more pounds.

In general, center console boats weigh between 1,100 and 8,500 pounds depending mostly on their size. Their engine, gear, and fuel add another 470 to 2,000 pounds, and their trailers weigh around 500 to 2,000 pounds.

There are many different lengths and types of sailboats including both single-hull sailboats and catamarans. So their weight of them changes drastically depending on the exact make and model. However, According to Lifeofsailing.com , here are the general statistics:

On average, cuddy cabin boats weigh around 1,500-4,500 pounds mostly depending on their length. Their gear and fuel generally add another 500-800 pounds and their trailers generally weigh around 800-1,800 pounds.

Small cabin cruiser boats (30-40 feet long) weigh around 10,000-22,000 pounds. Larger ones (41-50 feet long weigh around 24,000-42,000 pounds. Their gear and fuel generally add another 1,100-4,800 pounds .

There isn’t an exact standard that defines yachts; however, in this article, I am considering them to be any recreational vessel over 50 feet long. It’s hard to find averages of boats this big as they vary a lot depending on the make/model. However, my data below is an average of three different models within each length, so it should at least give you an idea of how much a boat around that length should weigh.

On average, yachts that are 55-65 feet long weigh around 75,000-100,000 pounds, yachts 66-75 feet long weigh around 105,000-128,000 pounds, and yachts 76-90 feet long weigh around 137,000-205,000 pounds. Their gear and fuel add another 12,000-30,500 pounds.

How to weigh a boat?

The most accurate way to weigh a boat is to take it to a truck scale. Make sure it has all the gear and equipment in it that you need to have and weigh it. Also, note the amount of fuel that is in the boat as well. Gas weighs about 6 pounds per gallon, and boat fuel tanks can hold anywhere from 15 to thousands of gallons. You can then subtract out the weight of the trailer (which can be found by either weighing the trailer separately or just estimating using my averages).

Here’s what a truck scale looks like:

You can find these by just searching truck scale near me. Then try to contact them in advance or just show up at a location and they will most likely be happy to assist you if it’s within working hours.

If you’re unable to do that, most manufacturers will have the weights listed on their website; however, you may still have to do some estimating for engine, gear, & fuel weight as well as trailer weight. The data I provided above should also help you out with that.

What are the best vehicles for towing boats?

Making sure you are using a capable towing vehicle is crucial for the safety of you and others on the road when you are towing a boat. You can see a vehicle’s towing capacity by searching the make and model of the vehicle and then typing “towing capacity” after in the search bar.

It’s generally recommended to have a vehicle that is capable of towing 1,000 more pounds than the total weight of what you are towing. So in this case, the GTW would be the total weight.

Depending on how much your boat weighs, there will be different vehicles that would fit you best. However, below are a few popular vehicles used for towing boats:

Here are some popular SUVs used for towing boats

• Can tow up to 5,000 pounds.
• 2- or 4-wheel options.
• Can tow up to 7,800 pounds (V8), or 6,200 pounds (V6).
• All-wheel drive.
• Can tow up to 7,400 pounds.
• Turbodiesel option available.
• Can tow up to 8,000+ pounds depending on the model.
• Can tow up to 9,300 pounds.
• Can tow up to 8,300 pounds.

And here are some popular trucks

• Can tow up to 6,700 pounds.
• Can tow up to 7,000 pounds with the gas engine, and the diesel model adds around 700 more pounds of towing capacity.
• Can tow anywhere from 8,000 to 9,000 pounds.
• Can tow anywhere from 9,700 to 10,900 pounds.

How Much Do Boats Weigh? (Weight Chart)

Boating is one of the favorite leisurely activities worldwide. If you can buy a boat , you should do so. However, you need to check a few crucial things before taking such a step. For instance, it is crucial to know how much do boats weigh and the appropriate length that will suit your needs.

This information is not crucial while your vessel is on the water but will help you find a way of transporting your boat. If you want a more sizable vessel model, you may need to change your vehicle because of its towing ability. Plus, its weight will affect the trailer type you need. Let’s see.

Table of Contents

Dry Weight vs. Wet Weight

The most towable boats, vehicle towing capacity.

The primary thing before determining how much do boats weigh is to know what does it really mean.

This boat’s dry weight is its mass you can find on the manufacturer’s instructions. It includes only a vessel without an engine, fuel, equipment, passengers, and trailer .

This measure includes the weight of the boat with an engine and fuel. Be careful when determining it since motors are heavy and can carry gallons of gas.

Remember that each gallon (3.8 l) of fuel weighs 6 pounds (2.7 kg). In other words, an average tank with 60 gallons (227 l) capacity will add at least 360 pounds (163 kg) to the boat’s dry weight.

Package weight

This weight type includes a boat with an engine packed with fuel and trailer weight . It is the weight your car needs to tow once you decide to transport the boat. Remember that a trailer size directly depends on your vessel length and weight.

Actual boat weight

It is the weight of your fully-equipped vessel with a trailer . It includes a boat with a fully fuel-filled engine, passengers, and gear, like:

• Fishing gear

When these things add up, they significantly increase the final boat’s weight. Unfortunately, it is impossible to precisely calculate this measurement since the equipment is not standard and depends on your needs and boat type.

However, you can check the weights of gear most people typically carry on their vessels. Then, you can pick out things you plan to load on your boat and make a calculation.

• The trailer is approximately 1,000 to 1,600 pounds (455 – 725 kg) heavy
• Fuel weighs 240 to 450 pounds (110 – 205 kg), depending on the gas tank size
• Tower weighs 70 to 300 pounds (30 – 136 kg)
• Standard gear, like life vests and coolers, can reach 100 to 500 pounds (45.5 – 225 kg)
• Stereo with speakers and amps are about 50 to 250 pounds (22.5 – 115 kg) in weight
• Accessories, including ballast tanks and heater, will add 50 to 450 pounds (22.5 – 205 kg)

As you can see, you will potentially add an extra 1,500 to 2,200 pounds (680 – 1,000 kg) to the dry boat weight. Plus, you also need to calculate the number of people coming to your boat and their average weight.

Even though it is only a rough estimate, you can get an idea of things that impact your vessel’s weight . Plus, you will know what to expect before picking out a vehicle to tow it and determine the load your boat can carry while sailing.

The boat’s weight will directly affect its towing capability. Therefore, you should check all possibilities before choosing the model you want to buy.

A skiff is a mini, under 20 feet (6 m) long boat suitable for shallow water and tight fishing spots. It is typically 300 to 900 pounds (135 – 410 kg) heavy and comes with a small light motor .

You can move this vessel made of light materials like aluminum or fiberglass with a long pole. It is also practical for towing, and you only need a car or crossover for such an activity.

Fishing boat

An average fishing boat can weigh 300 to 2,500 pounds (135 – 1,100 kg), depending on the material used for its making. Most people pick out one of the standard models weighing approximately 1,700 pounds (770 kg).

The excellent thing is that you can tow it effortlessly, but the type of vehicle you need directly depends on your vessel type and weight. You can tow smaller models with your car, crossover, or SUV, but you need a truck for towing heavier boats.

Aluminum fishing boat

An aluminum fishing boat is 16 feet (4.9 m) long and 300 to 500 pounds (135 – 225kg) heavy on average. It comes with a flat or a deep V bottom and uses a small electric or outboard gas engine . All in all, its weight is almost always under 1,000 pounds (453.5 kg).

If you have a fishing boat with a small motor , that weight will be about 650 pounds (295 kg). A sizable engine increases that value to about 900 pounds (410 kg).

Fiberglass fishing boat

This durable, 16 to 20 feet (4.9 – 6 m) long fishing boat is typically 1,500 to 2,500 pounds (680 – 1,100 kg) heavy. Some sizable models can weigh 2,900 pounds (1,315 kg). You can expect it to reach at least 5,000 pounds (2,270 kg) with an engine and trailer.

Personal watercraft

PWC (personal watercraft) is often known as Jet Ski and Wave Runner. It is technically not a boat, but people who enjoy fun water activities consider it a one-person boat. With a weight of only 800 to 850 pounds (363 – 385 kg), it is in a group of lightweight vessels you can carry with a car, SUV, van, or truck.

Sailboats are vessels you need to propel by sails. They come in wide weight ranges, and you can find models weighing 120 to 36,000 pounds (54.5 – 16,330 kg).

In other words, it can be tricky to transport if it is hard to tow it. You should have a car or crossover for smaller models, but even trucks can’t tow the most sizable ones weighing over 12,000 pounds (5,443 kg).

You can roughly divide sailboats into two groups, depending on their measures:

14 to 18 feet (4.3 – 5.5 m) long sailboats

So-called day sailboats without onboard overnight accommodation are typically 14 to 18 feet (4 – 5.5 m) long. Most models weigh 400 to 800 pounds (180 – 360 kg) in total. It primarily depends on the material they are made of, including aluminum , fiberglass, or wood .

You can pick out this model to sail on calm waters like lakes and bays. A car and crossover are typically strong enough to tow this boat even long distances.

20 to 30 feet (6 – 9 m) long sailboats

You can use 20 to 30 feet (6 – 9 m) long sailboat for family cruising, but some models include cabins for sleeping. Vessels over that length are considered yachts. The expected weight is 4,000 to 8,800 pounds (1,800 – 4,000 kg), and you can have difficulties carrying your boat even with a truck.

Bowrider boat

This boat type made of fiberglass is a desirable option for comfortable short cruises. You can find 16 feet to 25 feet (4.9 – 7.6 m) models with an inboard or outboard engine . Their total weight is 3,000 to 3,500 pounds (1,350 – 1,600 kg) on average, so you need an SUV or truck to tow it.

Pontoon boat

Most pontoon boats with two or even three hulls weigh 3,000 to 5,000 pounds (1,350 – 2,300 kg). As you can guess, only an SUV or truck can tow such a sizable vessel.

Be careful if you have a small SUV since some models can’t deal with such a weight. Pus, always check this boat’s width to prevent possible problems with towing it along the road.

Thanks to enough deck space, a deck boat is an excellent 20 to 30 feet (6 – 9 m) long option for family day cruises. They are similar to pontoon boats but with only one hull. Since most models are 3,000 to 5,000 pounds (1,350 – 2,300 kg) heavy, you will need an SUV or truck for transportation.

Cuddy cabin

With a small sleeping area and short-term cruising capability, this boat combines a bowrider boat and cabin cruiser. You can find it in the 20 to 30 feet (6 – 9 m) length range.

Its weight is 3,000 to 5,000 pounds (1,350 – 2,300 kg) on average. Considering these measures, you can see that only a sizable SUV and truck are options for towing.

This vessel is an excellent option for watersport enthusiasts and surfers, thanks to its ability to make waves behind the hull. Most models are 20 feet (6 m) long with 3,000 to 5,000 pounds (1,350 – 2,300 kg) of dry weight .

Since you need to add an engine and tailor weight to this number, you will need an SUV or truck for safe transportation.

An average ski boat will weigh 3,500 pounds (1,600 kg), but you can find them in a weight range of 2,000 to 6,000 pounds (910 – 2,700 kg).

This vessel model has become highly popular in recent years because of activities you can use it for, like water skiing and wakeboarding . The only way to effortlessly tow this boat is to have a middle-sized SUV or truck.

The so-called cigarette boat has a slim and stylish outer design that can vary depending on the model and make. Its purpose is to be fast and provide the thrill of the ride.

This sleek and stylish boat typically comes with an average weight of 8,000 pounds (3,600 kg). However, you can find drastic weight differences because of robust engines.

Even though this vessel is not challenging to tow, you need to have a sizable SUV or truck for this purpose.

Cabin cruiser boat

A cabin cruiser is actually a small, 25 to 45 feet (7.6 – 13.7 m) long yacht weighing 9,000 to 16,000 pounds (4,000 – 7,250 kg) on average. It is like a mini portable house you can use on the water with enough inside space for sleeping when necessary.

Keep in mind that the sleeping accommodation size will directly affect its weight. You can consider buying this vessel only if you have an appropriate truck for towing.

Before buying a boat , you need to determine its weight with complete equipment and trailer to determine the vehicle type you need to tow it. If you pair the wrong car with a too heavy boat, you will probably cause irreparable damage and lose money instead of enjoying sailing.

The only option you can make is to think of purchasing an adequate vehicle before considering a heavier boat type.

The boat weight is a vital deciding factor you should keep in your mind before purchasing one. You should check both dry and wet weight to ensure your safety while on the open waters. Plus, this measurement will help you pick out the proper trailer and match it with the vehicle you own.

How Much Does A Sailboat Weigh?

Last Updated by

Daniel Wade

June 15, 2022

While it may seem counterintuitive, there's more than one weight measurement for sailboats. In this article, we'll go over three ways of determining the weight of a sailboat.

Consumer sailboats usually weigh between 120 and 30,000 pounds, with the average sailboat weighing 8,845 pounds. This average sailboat weight is without taking into account additional gear, fuel, people, and more that are on a sailboat out on the water. To accurately weigh a boat isn't as simple as dropping it on a scale.  Besides the logistical problems you'd face, it wouldn't give you all the information you need to know.

That's why there are a few types of weight measurement for boats.  These are dry weight, displacement, and tonnage. Don't confuse these subtypes; while displacement and dry weight are closely related, tonnage is a different type of measurement.

Table of contents

Dry weight is closely related to displacement, and it’s the number you’d get if you hung an empty boat from a scale.  Dry weight isn’t always included on specification sheets, but it’s vital if you intend to tow or transport your boat.  

To give you a better idea of the dry weight of different vessels, we’ll use a short list of common boat sizes by LOA (length overall) in feet.  Keep in mind, the weight of a boat differs based on hull material , mast type, and many other factors.

• Dinghies (less than 12’): 100 to 200 pounds
• Small Sailboats (15’ to 20’): 400 to 2,500 pounds
• Medium Sailboats (21’ to 25’): 2,500 to 5,000 pounds
• Cruising Sailboats (27’ to 32’): 7,000 to 12,000 pounds
• Large Sailboats (35’ to 40’): 12,000 to 30,000 pounds

What factors contribute to the weight of a sailboat?  Hull material makes a huge difference in dry weight.  Older wooden cruising vessels with deep keels often weigh thousands of pounds more than an equivalent-sized fiberglass boat.  Also, sport and racing sailboats sometimes weigh a fraction of an average consumer cruiser.  

A sailboat’s mast and rigging contribute to the weight as well.  Solid hardwood masts sometimes weigh hundreds of pounds more than hollow masts, and heavy brass deck equipment adds up.  It doesn’t take long for equipment to increase the weight of a boat.

Displacement

How is displacement different than dry weight?  First of all, you can only calculate dry weight when a boat is empty and dry.  Displacement is equal to the weight of a boat, along with everything (and everyone) aboard at the time of measurement.  This includes water, fuel, deck equipment, interior cushions—you get the picture.

The most common measurement of weight for sailboats is displacement, and it reflects the weight of a loaded sailboat in the water.  We measure displacement by calculating the weight of the water volume a boat displaces.  This unit is vital in boat design.  A vessel will sink if it weighs more than the water it displaces.  

There’s a simple way of picturing the concept of displacement.  Imagine a cup of water filled to the very top.  Now drop in a coin and measure the amount of water that spills out.  The weight of the spilled liquid is the displacement of the coin.   

Oddly, the displacement value of a boat means slightly different things in salt and freshwater.  Saltwater weighs 64.1 pounds per cubic foot, while fresh water weighs 62.4 pounds per cubic foot.  That means a boat will displace more freshwater because saltwater essentially ‘pushes harder’ upward on the craft.

So, how does displacement translate to weight?  You can get a general idea of how ‘heavy’ a boat is using a simple calculation, shown below.

‍ (Displacement/2,240) / (LWL x 0.02)^3

1)    First, you’ll need to convert the displacement (in pounds) to long tons .  Simply divide the displacement by 2,240 to get your answer.  Put this number aside for a moment.

2)    Next, find the length at waterline ( LWL ) of your boat, and multiply it by 0.01 .  Take this value and raise it to the power of 3 .  It should look something like this: (LWL x 0.01) ^3

3)    Finally, divide your first number (in long tons) by the result of the previous calculation to get your displacement to length ratio .

The displacement to length ratio is useful for a number of reasons.  Using this simple number allows you to determine the weight class of a boat, so you’ll know what it’s suitable for.  Below, we put together a list to help you understand the differences using a D/L ratio of 40 to 400.

• Ultra-light (race boats): 40 to 89
• Light (race or trailer-sailboat): 90-179
• Medium (day boat/light cruiser): 180-269
• Heavy ( cruising sailboat /offshore cruiser): 270-359
• Very Heavy (heavy offshore cruiser): 360-400+

Generally speaking, sailboats built before 1950 typically have a heavy D/L ratio.  A boat with a ratio over 300 handles much differently than a light vessel, and many consider heavier boats to be more ‘seaworthy.’  Of course, it’s not always that simple, but the general rule still applies.  Using what we know about displacement, it’s time to go over our final weight measurement.

Tonnage represents the volume of the enclosed space on a boat, using the same concept as displacement.  Salt and freshwater tonnage differ for the same reasons as well.  Tonnage and size are directly related, and this unit gives you an idea of how much cargo you can carry before overloading.  Cargo tonnage is measured in long tons, similar to displacement.  Simply divide the tonnage (in pounds) by 2,240 to get your cargo tonnage value.

Why Weight Matters

While we haven’t mentioned every way of weighing a sailboat, you can gain a lot from understanding dry weight, displacement, and tonnage.  For example, you’ll need to know the dry weight of a boat to determine if your vehicle can actually tow it.  If a vessel weighs 15,000 pounds, you’ll probably want to avoid it unless you have a permanent mooring or a heavy-duty pickup truck.  

Displacement and dry weight are closely related.  Displacement is equally crucial for determining a boat’s capabilities.  Heavy, deep-keel sailboats generally handle well in rough seas, but you probably won’t be racing with a high D/L ratio.  If you understand what your intentions for a boat, it’s imperative to comprehend displacement and D/L ratio.  

Tonnage is essential to understand, especially for offshore cruising.  Using this value, you can calculate how much food, water, supplies, and how many people you can take aboard.  Ignoring any of these values can spell disaster for any captain but understanding sailboat weight ahead of time ensures you’ll know what you’re doing.

Now that you have a grasp of sailboat weight measurements, it’s time for some real-world examples.  We found the specifications of three common sailboats so you can get an idea of what to expect.

This 30-foot sloop is one of the most successful production fiberglass sailboats in history.  It was built by Catalina Yachts between 1972 and 2008, with over 6,000 units.  We chose the Catalina 30 because it’s an ideal example of a medium-sized all-purpose cruising sailboat .  This versatile sloop is well suited for coastal cruising and some offshore passages.

Dry weight clocks in at 10,200 pounds, with a D/L ratio of 291.43.  This sailboat is an ideal general-purpose cruising vessel.

How Much Does An O’Day 25 Weigh?

Despite being only a few feet shorter than the Catalina 30, the O’Day 25 is a much different boat.  This popular day cruiser has a displacement of only 4,007 pounds, which is less than half of the Catalina 30.  The O’Day 25 falls into the medium weight category with a D/L ratio of only 193.16.  Comparatively, you can immediately see how these two common fiberglass boats differ.  The O’Day 25 will be much easier to tow, yet less suitable for long offshore passages.

How Much Does An Atkin ‘Eric’ 32 Weigh?

This 32-foot wooden sailboat was designed decades ago for offshore sailing.  While dimensionally similar to the Catalina 30, this boat is significantly heftier with a displacement of 19,500 pounds.  Despite only being 2-feet longer than our Catalina at the waterline, the Atkin Eric has a D/L ratio of 418.81 making it an extremely heavy boat!

From a distance, all three of our examples would look similar in size and above-water characteristics.  Below the surface, we find something very different.  Each of these vessels is suitable for different things, and how much they weigh plays a vital role in their uses.  Now that you know how to interpret the weight of a sailboat, you’ll be prepared to choose one that best fits your needs.

A heavy sailboat can come with plenty of pros and cons, depending on the size and type of boat you’re looking for.

On the plus side, a heavier sailboat can be more stable in choppy waters and can withstand stronger winds and waves.

It can also be more durable over the long-term, as it’s less likely to be damaged by the elements.

Additionally, a heavier boat will have more room for storage and can accommodate more passengers or cargo.

On the downside, a heavy sailboat can be more difficult to maneuver and take longer to accelerate.

It can also be more expensive to transport and may require a larger trailer.

Additionally, it can be more expensive to maintain and repair, as it may require larger and more expensive parts.

Finally, a heavy sailboat will require more energy to move, meaning it will cost more in fuel or power to get it where you need to go.

Final Thoughts

From a small sailboat weighing 500 pounds to a large one weighing up to 50,000 pounds or more, the weight of a sailboat can vary greatly.

The size, type, and material of the boat are all important factors to consider when you’re looking to purchase or transport a sailboat.

If youre looking into buying a sailboat, make sure to calculate its weight appropriately to ensure you have the right sailboat for your needs.

Boat Weight Estimates For 7 Weight Boat Types

If a vehicle treads water, it’s a boat. That’s why boats can come in so many shapes, sizes, and types, each having its own weights and weight capacities.

With so many varieties out there, we have created this page to explain the average boat weight for the most popular boat types available on the market.

Boat weight metrics can be difficult to understand, especially if you’re new to boating, so learning how it works with several boat types can help.

While each individual boat will weigh differently, we can estimate the dry weight of each boat to some success. We have included examples of boat models throughout the page to show that these weights are found in the wild.

Side note: the weights mentioned in this guide are dry weights – the weight of the boat without having fuel and leisure gear stored aboard.

This means that a fully-kitted boat will be heavier. With fuel, interior equipment, and a trailer attached, you can increase the total weight by approximately 2,000 pounds.

We have broken down each boat type and their average weights below, including details about the vehicles you’ll need to tow each boat category.

If you want a quick rundown, here’s a convenient table that should have the answers you seek:

Boat Weight Estimates

There’s only so much a table can communicate, so let’s go into more detail about each boat type and how much they weigh. We have seven different types of boats below, ranging from under 1,000 pounds to over 30,000 pounds!

1. Personal Watercrafts (PWCs) – 850 Pounds

First, there are personal watercraft. PWCs are the smallest boats that we have covered on this page, though some would argue they aren’t boats at all.

They are also more affordable for the average person and so they are a very popular choice, so it’s better to include them for those that need weight information on PWCs .

Naturally, their small size means they have an average dry weight of just 850 pounds.

This can vary by a few hundred, as demonstrated by PWC models like the Sea-Doo Spark (450 pounds) and the Kawasaki Ultra 310 LX (1,074 pounds).

So, while the average PWC is 800-850 pounds, you can find many other small water-treading vehicles that weigh a little more or less.

In this case “a little” is a few hundred pounds but, when you see the hefty boats we’re covering on this page, that’s a relatively small difference.

Where towing is concerned, PWCs can be towed by cars, which is another reason that they are so accessible.

Some cars can even pull two personal watercraft at once, as can larger vehicles like SUVs and trucks for those who have families. Needless to say, anything larger and stronger than a car can also pull a PWC with ease.

2. Sailboats – 8,800 Pounds

Sailboats are the most varied kind of boat, being made up of personal vessels that don’t fit into other categories.

Go to your local port and scope out the marina, you’ll see that the boats there vary wildly in size, shape, and weight, and most of them will be sailboats with sails.

Our average sailboat was 8,000 to 8,800 pounds, though some popular boat models like the Sunfish are technically sailboats despite weighing just 120 pounds.

They look and weigh more like a dinghy boats or a kayak than the larger sailboats out there, and you’d probably mistake them for one at a glance, but they are the smallest sailboats.

As for the heavier boats, you have smaller models like the C&C 27 at approximately 5,000 pounds and then larger ones like the Swan 48, which is 36,000 pounds.

That makes the Swan 48 the single largest boat mentioned on today’s page.

With such variety between sailboats and how large they can be. Those smaller 120-pound sailboats are much easier to tow than a 30,000-pound monstrosity, for example.

An SUV can tackle smaller boats but you’ll obviously need something more substantial for larger boats, and some are so large that they just cannot be towed and are better off stored in the water, ready to go.

3. Ski Boats – 3,500 Pounds

Where personal boats don’t have sails, they are usually ski boats that use a motor to get around. Unlike sailboats, it’s much easier to estimate how heavy a ski boat will be.

The average is 3,500 pounds but it can be below 3,000 pounds in some cases and, with large boats like the Malibu Wakesetter 2017 24MXZ, up to 4,800 pounds. Larger models can touch 6,000 pounds, too.

Ski boats have become more popular in recent years, especially as water sports have become more popular.

You can wakeboard or water ski from a ski boat that can travel at faster speeds, not from a sailboat that gently follows the wind.

As such, ski boats tend to be the favorite of those in warmer climates where water sports are more accessible and fun to perform.

As for how towable they are, most ski boats can get towed by SUVs and trucks though you should always check beforehand.

It’ll vary between boat types and what vehicle you have, obviously, so maybe your vehicle isn’t up to it. In those cases, you can get a larger vehicle to cater to your needs.

4. Cabin Cruisers – 8,700 Pounds

Cabin cruisers are another type of boat that’s pretty heavy, alongside the larger sailboats out there. This makes sense since cabin cruisers, as the name suggests, are boats that are better adapted for living in.

They have more beds and dining areas, like an RV contained in a boat, and so they need to be heavier to accommodate that. Cabin cruisers are sometimes described as mini yachts, which is the best way to think of them.

The average cabin cruiser is somewhere between 8,000 and 8,700 pounds.

Smaller models like the Larson Cabrio 274 are 2,000 pounds lighter (weighing in at approximately 6,000 pounds) while larger models like the Rinker Express Cruiser 301 can weigh 12,000 pounds.

Naturally, the capacity of the boat will play a large part in how heavy the vehicle is.

If the boat is just for you, you can get away with a much smaller model than a cabin cruiser that needs to house an entire family. Some cabin cruisers can comfortably accommodate ten people or more!

Just like with larger sailboats, heavy-duty vehicles will be needed to tow them. Some larger SUVs may be up to the task but a truck is the safest bet.

Smaller cabin cruisers can get towed by most SUVs but, as always, check first. The SUVs and trucks need to weigh more than the cabin cruiser they are trying to haul around.

5. Speed Boats – 8,000 Pounds

Speed boats are similar to ski boats and they are often conflated, though there is a difference between them.

Speed boats are sleek and fast – faster than any ski boat out there – and are instantly recognizable after decades of representation in pop culture.

While they are the height of fast-paced, sea-faring decadence – speed boats are too fast to safely perform water sports on them, so you’ll need a ski boat for that.

The average speed boat should weigh approximately 8,000 pounds, which is mostly from the powerful motor and mechanics inside the boat.

Lighter models, like the Thunder Cat 32, weigh around 5,000 pounds while boats like the Cigarette Top Gun 38 weigh 9,000 pounds.

Counterintuitively, the faster boats tend to weigh more since they need larger engines and motors to slice through the water and move faster.

Many SUVs and trucks can tow speed boats, with lighter models being more accessible for towing. If your boat is around 5,000 pounds, most SUVs should be up for the job, otherwise, a heftier truck may be ideal.

6. Pontoon Boats – 3,100 Pounds

Pontoon boats are large but light boats that have decks for people to hang out. They are very similar to deck boats, though they tend to be faster and pontoon boats are better for slower, chilled recreational activities.

The average pontoon boat weighs 3,100 pounds. An example of a lighter pontoon boat would be the 2,100-pound NauticStar Angler 193 SC. As for a heavier pontoon boat, the Hurricane 2690 SunDeck weighs over 4,400 pounds.

As you’d expect, the weight correlates with how large the deck is and how many people that deck can accommodate.

In the grand scheme of boating, 3,000 pounds isn’t that heavy. As such, pontoons and deck boats can be towed by larger SUVs and trucks with no trouble.

Smaller SUVs and trucks shouldn’t be used to haul them around, they may not be up for the task.

7. Small Fishing Boats – 1,700 Pounds

Our last boats are some of the most practical – fishing boats. You’re probably not looking to get an industrial-grade trawler, so we’re talking about small fishing boats that your average Joe can buy and enjoy.

These are sometimes called bass boats too, and their design accommodates equipment that can be as simple as fishing rods or as complex as a mini radar system.

For these boats, the average weight is 1,700 pounds. Some, like the Tracker Pro 2017 170, weigh under 1,000 pounds while others, like the Bass Cat Jaguar, weigh over 2,000 pounds.

The heaviest fishing boats weigh around 2,500 pounds.

Smaller fishing boats are some of the lightest, which makes sense considering they are designed for fishing trips.

This means they have been made with towing in mind, so the effort is made to keep them light and towable for the typical angler.

As such, many mid and heavy-sized SUVs can tow all fishing boats while smaller boats can be tackled by a smaller SUV as long as the SUV is heavier.

Factors That Affect Boat Weight

As we said at the start of this page, the weights we have discussed so far are dry weights.

This means it’s the weight of the boat itself, without many of the amenities or the fuel that it’ll get pumped full of, which adds extra weight.

Think of it as the minimum that the boat will ever weigh, which is why it’s useful for knowing how heavy the boat is and its ability to get towed when empty.

So, if you want to know the total weight of your boat, you’ll need to consider the other factors. Here are some of them:

• Fuel, which can add a minimum of 200 pounds to the boat. At most, 500 pounds can get added by a full gas tank on larger boats.
• General gear/amenities, which is everything from life vests to snacks and portable storage like coolers. These can weigh between 100 and 500 pounds depending on how kitted out your boat is.
• Electronics, particularly things like amps and speakers, and a TV if the boat can accommodate it. These electronics can weigh between 50 pounds and 300 pounds.
• Towers, which are usually optional but will be needed for activities like wakeboarding, can add as much as 50 to 300 pounds.

Using those numbers, outfitting your boat can add anywhere between 400 and 1,600 pounds. If you can think of other equipment that you’ll add to the boat, it can easily exceed 2,000 pounds added once the boat is ready to be at sea.

If all this estimating is frustrating for you, you wouldn’t be the first! Most boats are weighed through calculations and estimates since most boat owners don’t have access to industrial weighing scales.

That said, you can hook up your boat and use the same weighing scales that truckers use to measure the weight of their hauls. This will give you an accurate measurement, down to the ounce.

Then you don’t need to worry about estimating how much your boat weighs and you’ll always match it to the right vehicles for towing.

That should be everything you want to know about the different types of boats and how much they weigh.

We have covered seven of the most popular boat types and given you accurate readings on many different models, along with an average figure for that category. 

Using those, you should be able to figure out how much your boat weighs if you have one already. If not, you can get the right boat for yourself.

Knowing the exact weight of your boat can also be useful, so you can always weigh your boat at an industrial weighing scale if you want more accurate readings.

As a rule, larger boats will weigh more than smaller ones.

The two most notable exceptions come with speed boats and pontoon/deck boats, where the smaller speed boats are packed with heavy machinery while the pontoons are mostly deck, so they are lighter.

How Much Do Sailboats Weigh?

Sailing is an unquestionably wonderful experience. Cruising to new shores, relaxing in the sun, feeling the smooth breeze, racing, and other remarkable adventures are some of the things you can experience. Sailing gives us worthwhile and stimulating moments, but it also requires us to be aware of our sailboat’s characteristics. In this article, I’m going to refer to the factors affecting a sailboat’s weight, give you some examples, as well as provide you detailed information about them. Follow me!

Why Weight Matters?

The weight of sailboats is separated into three different categories of weight measurements: dry weight, displacement, and tonnage. Understanding the way in which each one of these methods function means understanding your sailboat’s weight. Each of these methods plays a crucial role in order to accurately determine a sailboat’s weight. For instance, dry weight and displacement are closely related. Displacement is a vital element for determining your sailboat’s capabilities. Heavy and deep-keel sailboats manage well in rough seas when you’re not racing with a high D/L ratio.

Keep in mind that there’s a lot of factors that affect a sailboat’s weight, like its hull type, length, mast and rig setup, gear, and onboard equipment. In order to know the dry weight of your sailboat, you’ll need to first determine if your vessel can actually tow it. Moreover, tonnage is also important, especially for long-passage cruising. With tonnage, you can calculate the number of supplies, water, and how many people you can take on board.

Towing and Vessel Capabilities

It’s of high importance to know the weight of your sailboat if you plan on towing it. In other words, its weight will determine if it can be towed, and with what type of vessels it can be towed. In case you wish to transport your sailboat to different areas with another vehicle, then you have to know your sailboat’s weight. The capabilities of your sailboat determine your sailboat’s weight. For example, if it’s able for racing or if it can handle rough seas, and how fast or far it can go.

Imagine placing your sailboat on a scale. The number that appears on the scale would be what we call dry weight. Dry weight is basically how much a sailboat weighs when it’s both empty and dry. In other words, the weight when there’s no extra weight on board. This type of measurement is important in case you plan on towing or transporting your sailboat with a vehicle. This is because the dry weight of your sailboat will be the weight you’ll have to tow. In addition, there are other things that affect the weight of the sailboat. These are the mast and rigging type, the hull material (wood or fiberglass), and deck equipment.

For example, solid hardwood masts often weigh hundreds of pounds more than hollow masts, as well as heavy brass deck equipment that also adds up weight. All these elements contribute to the dry weight of a sailboat and can make a significant difference in weight.

Displacement

Displacement is the most usual form of weight measurements in sailboats. When the weight of a sailboat is listed somewhere the displacement method is often used to define its weight. The displacement of a sailboat is equal to its weight, along with every other weight onboard at the time of measurement. This can include fuel, water, deck equipment, gear, etc. This method is called displacement due to the fact that measures the amount of water that the sailboat displaces. To give you a better idea about it, a sailboat has to weigh less water than the water it already displaces, otherwise, it could sink.

So, we calculate the weight of the water volume that the sailboat displaces. However, the displacement value of a sailboat differentiates in salt and freshwater. This happens because saltwater weighs 64.1 pounds per cubic foot, and freshwater weighs 62.4 pounds per cubic foot. And what does that mean? It means that a sailboat will displace more freshwater because saltwater basically has an upward direction towards the vessel.

Tonnage, size, and displacement are directly related. But, what exactly is tonnage? Tonnage is the volume of the sailboat’s internal space and also helps to define the cargo-carrying capacity within it. As for the freshwater and saltwater displacement’s difference, the same thing also applies to tonnage. Furthermore, cargo tonnage is measured in long tons, the same way with displacement. In other words, to get the cargo tonnage value you just divide the tonnage in pounds by 2,240.

Examples – Common Sailboats

• Small Sailboats : Small sailboats are considered the ones with an average length of 15 to 20 feet and an average weight of 400 to 2,500 pounds.
• Dinghies : Dinghies have an average length of fewer than 12 feet and their average weight is 100 to 200 pounds.
• Medium Sailboats : Medium-sized sailboats are those having an average length of 21 to 25 feet and an average weight of 2,500 to 5,000 pounds.
• Large Sailboats : Large sailboats are considered the ones with an average length of 35 to 40 feet and an average weight of 12,000 to 30,000 pounds.
• Cruising Sailboats : Cruising boats have an average length of 27 to 32 feet and an average weight of 7,000 to 12,000 pounds.

Examples – Weights of Popular Sailboat Models

• The Wayfarer (dinghy) is 15 feet 10 inches and weighs 400lbs.
• The Siren 17  has a length of 17.17 feet, and it weighs approximately 430lbs.
• The Catalina 16.5 Capri is 17.2 feet and weighs 430lbs.
• The Sea Pearl 21 is 21 feet and weighs 600lbs.
• The Hunter 22 has a length of 21,3 feet and weighs 2000lbs.
• The Jeanneau Sun 2000 is 21 feet 8 inches and weighs 2756lbs.
• The Beneteau First 235 is 23.3 feet and weighs 2826lbs.
• The Catalina 25 Capri is 24.6 feet and weighs 2950lbs.
• The Catalina 30 weight 10,200lbs
• The Jeanneau Fantasia 27 has a length of 27 feet 5 inches and weighs 3800lbs.
• The Cornish Crabber 22 is 27 feet and weighs 4480lbs.
• Sun Odyssey 30 is 29 feet 8 inches and weighs 7000lbs.
• The Catalina 350 is 35.4 feet and weighs 12,937lbs.
• Pearson 39 is 39.2 feet and 17000lbs.
• Beneteau Oceanis 40 is 39.9 feet long and weighs 18,210lbs.
• Beneteau Oceanis 45 is 45’9” and weights 23,257lbs
• The Valiant 40 weighs 23,500lbs
• The Hinckley Bermuda 40 weighs 20,000
• The Hallberg-Rassy 42 weighs 27,500lbs
• The Beneteau 57 weighs 47,500lbs
• The Jeanneau 54 weighs 37,840lbs

Common sailboats tend to weigh about 120 and 30,000 pounds. As for the average sailboat, this weighs around 8,845 pounds. Keep in mind that we refer to dry weight and don’t measure additional equipment, fuel, gear, etc. As aforementioned, in order to correctly weigh a sailboat, you’d need to take into account the three weight measurements. Furthermore, don’t forget that a sailboat’s weight is usually calculated without its engine, gear, water tanks, equipment, or persons in it.  In short, an average sailboat of15-20 feet weighs around 1047 pounds. Moreover, the average weight of a 21-25 feet sailboat is around 2826lbs and the average weight of a 27-32 feet sailboats is 5410 lbs. Finally, the average weight of a 35-40ft sailboat is approximately 18,918 lbs .

How Much Do Boats Weigh? 11 Boat Types Explained

Boats come in all different sizes and weights.

This can make it tough for people trying to find out whether or not they have the ability to tow certain boats with their cars and trucks.

In this post, we’ll try to make it easier by showing you the average weight of a wide variety of boats in different classes and sizes.

Here’s How Much Boats Weigh on Average

Smaller aluminum fishing boats typically weigh around 400 pounds and a 14 feet cabin cruisers will often weigh around 14,000 pounds. A superyacht can weigh up to 100,000 pounds.

Table of Contents

Here are some general boat weights to consider before we get into the details:

Aluminum Fishing Boats

The average aluminum fishing boat is about 16 feet in length.

It generally consists of the hull, a set of benches or chairs, and a center console for steering the vessel.

In some cases, the center console might be traded out for a seat near the engine instead.  At the rear is an outboard gas engine or a small electric motor .  Boats with rear gas engines will often have an electric trolling motor at the front as well.

The boat might have a deep v, a modified v, or a flat bottom.

Boats with a deep v will have a larger hull and a larger engine and will, therefore, weigh more than flat bottom boats.  A flat bottom boat can sometimes go by the name Jon boat.

These boats are meant to be used for fishing, and they are usually lightweight.  This is nice because it gives people with a wide range of vehicle types the opportunity to buy a fishing boat that they can safely tow.

In fact, most of these boats will weigh less than 500 pounds without an engine.

The tow weight will usually be less than 1,000 pounds.

Here are some quick examples:

The Lund WC-16

This boat has a small gas engine and bench seats. It’s a semi-v, and it is steered from the rear.

The weight is 325 pounds on this boat, without the engine.

Alumacraft 1648 Jon

The 1648 is a flat-bottom boat that does not come with an engine.

It has three benches and is meant to be steered from the rear.

The weight of this boat is 320 pounds.

Bowrider Boats

Bowrider boats are great for short cruises and are usually meant with seating comfort in mind.

They will often have an inboard motor at the rear but can also be equipped with an outboard motor instead.

These boats are steered from a console, and there is a windshield protecting the driver as well as the person next to the driver.

Bowrider boats come in a lot of different lengths, but the most popular length seems to be 21 feet.

The main material used to make this boat is fiberglass.

Fiberglass is heavier than aluminum, so this adds some weight to the boat.

Here are some examples of bowrider boats:

Regal 21 OBX

The Regal 21 is a 21-foot fiberglass bowrider with an outboard motor.  It can hold up to 10 passengers and has a large wrap-around windshield.

The dry weight on this boat is 3,250 pounds.

Yamaha Boats SX210

This boat is a 21-foot long boat with a fiberglass hull.

It has an inboard motor and a nice deck at the rear of the boat.

Additional features include a large windshield, wraparound seating near the steering console, and a set of lounge chairs at the bow.  There is also a built-in ladder at the rear for boarding.

The weight on this boat is 3,172 pounds.

Cabin Cruisers

A cabin cruiser is essentially a small yacht that ranges in size between 25 – 45 feet.

These boats have large fuel tanks and will often feature more than one engine.

They’re meant for long distances and come equipped with everything one would need to travel for days or even weeks at a time.

Related Article: How Do You Find the Owner of a Boat? (With Examples)

Inside of a cabin cruiser, you’ll find a head, a berth, and usually a dinette and galley.  The larger the cabin cruiser, the more living quarters you’ll find inside of it.

These boats vary in weight, but a 35 footer will usually range in weight from 12,000 to 16,000 pounds.

Here is an example of a cabin cruiser:

The Regal 35 Sport Coupe

This boat is a 37-foot long craft with sunbathing decks on the bow and the stern of the boat.  It has an inboard motor with a fantastic deck built into the stern for getting in and out of the water.

The fuel tank on this boat is 158 gallons, and the freshwater capacity is 50 gallons.

There is also a waste tank that can hold up to 30 gallons.

This boat weighs 13,300 pounds.

Cuddy Cabins

Cuddy cabin boats are a cross between bowrider boats and cabin cruisers.

They have the short-term cruising capabilities of a bowrider, but they also have a small area to sleep or eat inside.

This area usually consists of nothing more than a berth or a berth that can be converted into a dinette.  It is great for people looking to spend a night out on the water but not very good for people looking to spend an entire weekend out there.

Related Article: 13 Clever Ways to Get a Good Deal on (New) Boats

A cuddy cabin is somewhat larger than your average bowrider but smaller than a cabin cruiser.  You can expect to find them in the 20 to 30-foot range.

These boats usually weigh between 3,000 and 5,000 pounds.

Stingray 208CR Cuddy Cabin

This cuddy cabin is 21 feet long and has a fuel capacity of 34 gallons.

The water capacity is only 6 gallons, so its wet weight wouldn’t differ much from its dry weight.

The boat has outside seating for about four people while in motion and seating inside the interior space for two to three people.

The stern of the boat has a padded deck that you could sit on, but I wouldn’t do so while in motion.

Deck boats are built for day cruises and family fun.  Their design gives them a lot of deck space so that you can bring your large family or a bunch of friends out on the water with you.

These boats are similar to pontoon boats in that they offer a lot of room to move around.  However, they are built with a traditional hull, so they stand up to rough water better than a pontoon boat.

The size of this boat usually ranges between 20 and 30 feet.  Expect these boats to weigh between 3,000 to 5,000 pounds.

Here is an example of a deck boat:

The Bayliner 210 Deck Boat

The 210 is a 21-foot deck boat with an 8’6″ beam.

It weighs 3,468 pounds dry and 5,200 pounds dry if you include the trailer.  This weight includes a 150HP outboard engine.

A large SUV or small truck should easily be able to pull this boat, and at 8’6″ wide, it is perfectly trailer-able.

The boat is set up so that the only true chair on the boat is the captain’s chair.  Next to this chair, you’ll find an L shaped bench that can be used for people to sit on or lounge on.

At the bow, you’ll find a set of two benches that could also be used as lounge chairs.

Fiberglass Fishing Boats

Fiberglass boats weigh more, but they are often more durable, and the hull designs on them can often be more complex.

As a result, you get a boat that handles better in the water, and that should last a lot longer.

These boats cost more to buy, but they also depreciate slower, so you generally don’t lose out financially when you buy one.

A fiberglass boat can come in all sorts of sizes, but in this post, we’ll be comparing this boat’s weight to that of the smaller aluminum fishing boats.

This puts the boat in the 16 to 20-foot length range.

The weight on these boats is usually between 1,500 and 2,500 pounds without the motor.  With a larger engine and a trailer, you could be looking at a weight that is well over 5,000 pounds.

Here is an example of a fiberglass fishing boat:

The Grady White Fisherman 180

This fiberglass fishing boat is a center console fishing boat.

It has a reversible bench seat behind the console and a seat directly in front of the console.

There is a raised casting platform on the bow of the boat and a set of cushioned seats at the stern.  A swim platform with a ladder also resides at the stern.

Pontoon Boats

A pontoon boat is basically a flat deck mounted over two or three pontoons.

These boats are a lot of fun to cruise on as there is plenty of space to move around on them.

Some of these boats even have built-in grills so that you can throw barbecues on them.

These boats will often weigh in the neighborhood of 5,000 pounds with the engine and the trailer, so they are towable, but you won’t be able to tow the larger ones with a car, crossover, or minivan.

Sailboats Between 14 and 20 Feet

Sailboats come in all different lengths and weights, so we’ll break them into a couple of categories.  A sailboat between 14 and 20 feet is usually known as a day sailboat.

These sailboats are primarily used in protected waters like bays and inlets or on lakes and rivers.

They can be made from wood or fiberglass, and you can buy mass production sailboats as well as a wide array of custom-made sailboats.

Small sailboats like this don’t weigh much as they don’t have gas engines or fuel tanks.  They also lack living quarters so you won’t find heavy amenities or water tanks.

Expect them to weigh somewhere between 400 and 800 pounds.

Here are some examples of small sailboats:

The West Wight Potter 15

The Potter 15 is a 15-foot sailboat with a sloop design and a small cuddy area for sleeping.  It has teak cabin top handrails and a stainless steel transom boarding ladder.

This boat doesn’t have much on it other than two places to sit, and a place to sleep.  It weighs in at 473 pounds without the trailer and just under 1,000 with the trailer. 

In fact, the West Wight website shows a mini-cooper pulling it.

The Catalina 16.5

The Catalina 16.5 is a 17-foot sailboat with a roomy seating area.

It does not have a sleeping area, but there is a large locker at the bow for storage.

This boat weighs in at 429 pounds.

Sailboats 20 to 30 feet in length

Sailboats between 20 and 30 feet can be used as day cruising boats, or they can be outfitted with cabins for weekend getaways.

They can weigh anywhere from 4,000 to 8,000 pounds.

Sailboats that are larger than 30 feet are generally considered to be yachts.  At that point, you probably won’t be too worried about how much the boat weighs as you won’t be able to tow it anywhere anyway.

Here are a few examples of sailboats with lengths between 20 and 30 feet.

The Marine Concepts Sea Pearl 21

The Sea Pearl 21 is a no-frills sailboat that is built for day cruising.

It is wide open, and there isn’t any place to sleep, let alone to get shelter from the sun.

Without a motor or any extras, the Sea Pearl 21 weighs in at around 600 pounds.  This is about the best you can expect from a boat this long.

The Stuart Knockabout

The Stuart Knockabout is marketed as an upgrade over a smaller daysailer but more simple in its build when compared to a large cruiser.  It has a classic look to it, and if you dropped it onto the bay 40 years into the past, it probably wouldn’t look out of place.

This boat is 28 feet long, 8’6″ wide, and it weighs in at 4,000 pounds.

With these dimensions and this weight, it’s still easily towable.

The C&C 29 is made by Cuthbertson & Cassian, and it is a Canadian built sailboat.

This boat was originally designed for speed, but it functions perfectly well as a sailing yacht.

Inside there is a head, a galley, a berth, and a comfortable dining area.

This boat is just over 28 feet long, and it weighs in at 7,500.

Also, it is over 9 feet wide, so even if you have the truck to tow it, it will be considered an oversized load on the road.

A skiff is meant for shallow water.

Anglers love them because of their ability to get in and out of tight fishing spots.

These boats can be used with small motors, or they can be moved along with a long pole.

They’re typically under 20 feet, and they’re designed to be lightweight so that they can easily be poled through the water.  The lighter the skiff, the easier it is to get it moving without an engine.

Here are some examples of skiffs:

Xpress Boats Skiff 185

This boat has a length of 18’5″ and a beam of 83″.  It is made from 5052 gauge aluminum, and it has a bench seat behind a center console.

The weight of this boat is 950 pounds, so it is easy to tow, but it could be a little difficult to pole for long periods of time.

Hell’s Bay Boatworks Eldora

The Eldora is just over 16′ long, and it has a beam of 69″.

It is a shallow boat with a draft of only 3.5 inches.  This makes it a perfect shallow-water boat.

On top of this, the Eldora weighs only 350 pounds, so it is easy to pole manually.

When not poling, it has a Yamaha 25 engine and a 6-gallon removable gas tank.

Wake boats are for watersport enthusiasts who want to wake surf.  These boats are designed to create waves behind the boat for wake surfers to have fun on, so they’re definitely a niche item.

A wake boat is typically in the neighborhood of 20 feet long, and they generally have dry weights between 3,000 and 5,000 pounds.

Here are some examples of wake boats.

The Yamaha 212X

The 212X is a little over 21 feet, and it has a beam length of 8’6″.

It seats up to 10 people and can hold 50 gallons of fuel in its fuel tank.

This boat has a dry weight of 3,616 or 4,612, depending on whether or not you count the trailer.  A small truck or large SUV could easily handle a boat of this size.

The Supra SR

The Supra SR is a 21′ boat with a beam width of 102″.

It can seat up to 14 people, and the engine has a 45-gallon fuel tank.  This engine is either a 400HP engine or a 450HP engine.

This boat has a dry weight of 4,950 pounds, but when you add the trailer, it jumps up to 6,450 pounds. 

As a result, you’ll need either a large SUV or a midsize truck to tow the boat comfortably.

Final Thoughts

Different types of boats and different boat models will all have different weights associated with them.

On top of this, different trailers and engines will have different weights that you’ll have to consider as well.

When buying a boat, make sure you consider the boat’s weight with the engine, the trailer’s weight, and even the weight of the fuel, water, and gear that you’ll have inside of the boat during transit.

Average Weight of Sailboat Keels (5 Most Common Types)

The keel weight of sailboats differs greatly and can range anywhere from 200 to 12,000 pounds based on the keel type and boat length and use. The average keel weights are not readily available on the internet, so I've compiled an extensive list based on offline research and reasoning from fundamentals below.

Most sailboats carry around 35-45% of their total weight in their keel. An average 35-foot cruiser weighs 15,000 pounds, which means the keel will weigh between 5,000-6,000 pounds on average. Small sailboats carry approximately 200-1,000 pounds in their keel.

However, the keel weight is very dependent on the keel design. Different keel designs require different ballast weights. It's all determined by the ballast to displacement ratio, which I'll explain below.

On this page:

How much does a sailboat keel weigh, does keel material matter, how do sailboat keels work.

There are three ways to explore sailboat keel weight:

• based on sailboat size
• based on keel design
• based on popular sailboats

Below, I'll list the average keel weight based on all three factors, starting with sailboat size.

Keel weight based on sailboat length

However, the total required weight is not just determined by sailboat weight, but also by sail area and the length of the keel.

Keel weight based on keel design

Since the amount of ballast is very dependent on the boat length and indented sailing conditions, we have to make a lot of assumptions to pair each keel design to an average weight, making it an impractical comparison.

The difference in average keel design weights is mostly based on different standard applications of these keel designs. However, it is possible to show the effects of keel design on ballast weight requirements, by comparing the same class of boats with different keel designs.

Keel design weight differences

The examples below are the average keel weights on similar 40-foot cruising sailboats, using different keel designs, allowing for a comparison in ballast requirements based on design alone:

• Full keel : 8,000 lbs
• Bulb keel : 6,000 lbs
• Fin keel : 5,000 lbs
• Wing keel : 5,000 lbs

As you can see, the deeper the keel runs, the lower the required ballast will be. Bulb keels look like fin keels but are shorter, using more ballast to enable a shorter design.

Full keels and modified full keels run less deep, thus requiring more ballast to provide the same righting moment. Fin keels and wing keels run the deepest, reducing the amount of ballast needed.

Leeboards are unweighted, as are daggerboards most of the time. Centerboards can either carry ballast or not, based on the sailboat model.

Keel designs from heavy to light

We can also compare keel design weights based on their expected relative weight. So let's say we have a sailboat and we just switch out the keel, how heavy would each keel be relative to the others? From heaviest to lightest:

• Modified full keel
• Centerboards
• Daggerboards

Using the ballast to displacement ratio

The ratio used to describe the weight of the keel compared to the total weight of the sailboat is called the ballast to displacement ratio . You can use this ratio to get a general idea of the properties of a boat, but it does have major shortcomings.

For an overview of how to use the ballast to displacement ratio , I recommend reading my article on it.

While keels can be made out of several materials , it shouldn't affect the amount of weight you use. The ballast should be equal either way. Keel materials depend mostly on available space and budget. If you have restrictions on space, you need a heavier material to get the same amount of ballast. If you have restrictions on budget, you typically use something lighter. Having restrictions can be somewhat of a double bind.

In short, a sailboat keel's weight is used to to increase displacement and lower the center of gravity, while its surface is used to increase wetted surface. This helps to stabilize the boat, but also provides directional stability. For a more detailed explanation on how sailboat keels work , I recommend reading this article.

I am guessing the information here is for monohull boats, what about Catamarans and Trimarans?

Boat Weight Regulations

Advertisement

Portlier passengers have led to new rules from the Coast Guard. Could curvy cruisers be the next to get whipped into shape?

The average American has put on a considerable number of pounds in the past 40 years, so many that the U.S. Coast Guard recently adjusted the federal safety regulations governing the number of passengers that may be carried aboard commercial vessels, such as tour boats, water taxis, and ferries, meaning they're allowed to carry fewer people than before. The Coast Guard is concerned about what might happen if heavy passengers all move to one side, for example, when a ferry docks or an excursion boat moves in to view a migrating pod of whales. Will federal weight capacity regulations for recreational vessels change as well?

"We don't see a need to follow this line of action for recreational boats at this time," said Phil Cappel, chief of the Coast Guard's Recreational Boating Product Assurance Branch. He explained that the "recreational boat persons" capacity equation is based on a family of four — with an average weight per occupant of 165 pounds, and takes into account the variety of different boat types and hull configurations.

"As with all of our safety regulations, they're reactive and not proactive," Cappel explained, "which means we need to have proof that heavier boaters are increasing the number of accidents, injuries, or deaths before we can move forward with regulatory action. We have not seen any proof to that effect in our accident data."

Recreational monohull boats up to 20 feet in length are required to have capacity labels indicating what's safe to carry in terms of engine horsepower, cargo (including gear and engines), and passengers. Hull displacement — the mass of water a hull displaces when floating — is the basis for all weight capacity calculations. "Persons" capacity information includes both the number of passengers who may be carried safely, as well as the total weight of those passengers. It's the most prominent information listed on the capacity label, because people are considered to be the "live load," meaning they can move around inside the boat, affecting stability. Overloading a boat reduces freeboard and increases instability and the risk of swamping in rough weather.

Vessels of more than 20 feet aren't required to have labels, although boats up to 26 feet built to the American Boat & Yacht Council (ABYC) standards adopted by the National Marine Manufacturers Association (NMMA) do. An estimated 94 percent of recreational boats sold in the U.S. are built by 145 companies, all of which are members of NMMA and are required to follow the organization's boat and yacht certification guidelines.

The weight capacity ratings for commercial passenger vessels, which are governed by a completely separate set of federal regulations than for recreational boats, were adjusted in response to a report by the Centers for Disease Control and Prevention (CDC) showing that the average weight of an individual in the United States has increased to 185 pounds, up significantly since the passenger-carrying regulations went into effect in the 1960s, when the average American weighed 160 pounds.

"We realize that there is not always a family of four aboard a recreational boat and that the average weight of Americans has increased," Cappel said. "Recreational boats have a safety factor built into the capacity calculations and can carry much more weight than the maximum weight placed on the capacity label."

According to John Adey, ABYC's technical director and one of the BoatUS Ask The Experts, recreational outboard-powered boats can safely carry a pound of weight — in passengers, cargo, or engine — per five pounds of displacement. On inboard- and stern drive-powered boats, this "fudge factor" ratio goes to one pound of weight to seven pounds of displacement. He added that safe passenger loading is also controlled by the number of "underway seating positions." For example, two slim adults taking four or five small children out for a spin on a boat designed to seat four would be taking a big safety risk, even though the total passenger weight might be well under the boat's stated capacity.

Adey said that ABYC paid close attention when the Coast Guard announced changes to the commercial-vessel passenger-carrying regulations. "Everyone had the perception that [the criteria for determining] recreational boat capacities were about the same as those for commercial vessels." But, he said, the cargo-weight-to-displacement "fudge factor" makes loading recreational boats a bit safer.

Federal weight capacity ratings are not mandatory and are intended as a guide for boat operators. Even so, state boating law-enforcement agencies may hold operators accountable for overloading or unsafe loading.

Float Your Boat

Federal requirements mandate that outboard-powered boats 20 feet and under must be built with enough flotation to keep the passenger-carrying area at or just below the water's surface, in the event of swamping or capsizing. Inboard- and I/O-powered boats' designs warrant less rigorous basic flotation requirements, which allow that one part of the hull remain above the surface of the water. In both cases, a "survival platform" is created where boat occupants can stay until help arrives. If an overloaded boat swamps or capsizes, its built-in flotation may not be sufficient to keep the hull from sinking.

Sailboats, regardless of size, are not subject to flotation requirements — not because they don't sink, but simply because, by Coast Guard calculations, they're not involved in enough accidents to warrant tougher standards.

Weight, Weight — There's More!

Matching the correct horsepower engine to the boat is also an essential consideration that involves weight and safe loading. In addition to persons-weight capacity, boat labels must indicate the maximum horsepower the boat can safely handle. Horsepower capacity deals with two concerns that must be addressed when attempting to match an outboard engine to a boat: horsepower and weight. Too much power can make a boat difficult to control and too much weight, whether "live load" or gear, can lead to stability problems.

Federal horsepower ratings apply only to outboard engine-powered boats less than 20 feet in length. When these regulations were written in the early 1970s, virtually all outboards suitable for smaller boats were two-stroke configurations covering a broad range of horsepower. In the past decade, however, four-stroke outboard engines have broken higher and higher horsepower thresholds, making them viable candidates for installation on more boats. But, due to more complex valve systems, four-stroke engines weigh 10 to 15 percent more than their two-stroke counterparts.

Do boats equipped from the factory with four-stroke engines create a handling and stability risk? Are boaters who retrofit their vessels with four-stroke engines taking a dangerous chance? No, according to John Adey. Once again, the fudge factor that provides a margin of safety when loading passengers gives boat operators some leeway with engines. Plus, ABYC's engine-weight calculations are updated annually to reflect new models and new technology. Will federal standards be rewritten to include four-strokes? "Probably not," Adey says. "Once you achieve a high level of safety, there's no point in backing off.

One of the most important things you need to know before setting out on the water is the maximum number of people and maximum amount of weight that your boat can safely handle. Not only is this an important safety concern, it's also the law.

Federal Law mandates that all powerboats less than twenty feet in length need to carry this information in the form of a Capacity Plate.

Each Capacity Plate includes the maximum number of adult persons, the maximum gross load, and the maximum size of engine, in horsepower, that your boat can legally carry.

The next time you're around a boat, look for its Capacity Plate; it should be permanently fastened near the steering area, or the helm.

Before any boat trip, you'll want to make sure that you are not taking more people onboard than is indicated by the Maximum Person number, and that you don't have more total weight than is indicated by the Maximum Gross Load. The Maximum Gross Load is the total weight your boat can handle, including people, equipment, stores, fuel, engine assembly and steering controls. If your boat doesn't have a Capacity Plate, you can calculate the number of people you can safely take onboard using the following equation.

Boat Capacity Calculation

If your boat doesn't have a Capacity Plate, you can calculate the number of people you can safely take onboard using the following equation and calculator.

Number of people = vessel length (ft.) x vessel width (ft.) ÷ 15

First, find out the length and width of your boat in feet, then use our calculator to find out your boat's capacity.

Note that personal watercraft do not have a capacity place. For P-W-C's, always follow the recommended capacity in the owner's manuel and on the manufacturer's warning decal.

Finally, the Capacity Plate will also indicate the maximum engine power for your boat, given in horsepower. This number applies only to boats powered by outboard engines; and it must never be exceeded.

Maximum Person Capacity

There are a number of variables that boat manufacturers consider when determining the maximum person capacity that appears on your Capacity Plate.

One of those variables is the weight of each person.

Boat manufacturers typically use an average weight of about one hundred and fifty pounds per person to calculate maximum capacity. It can be a little more or a little less, but if some or all of your passengers weigh over one hundred fifty pounds, you may have to decrease the number of passengers you can safely take on board.

Remember, the maximum person capacity is a guideline that you have to adjust given the weight of your passengers and the other supplies you are taking on board.

If you are carrying heavy equipment, you may have to further reduce the number of passengers.

Maximum Horsepower

If you don't have a capacity plate on your boat—which may be the case if you're operating a small, flat-bottomed boat—you can calculate the largest safe engine size in the following way.

Maximum Horsepower Calculation: Boat length x boat width = boat square footage

First, find out the square footage of your boat by multiplying its length by the width of the transom.

Then use our calculator and the table here, to find out your boat's maximum horsepower. For example, a twelve-foot boat with a four-foot transom width translates into a maximum engine size of fifteen horsepower.

Overloading or Overpowering

Either overloading or overpowering your boat is extremely dangerous.

Putting an over-sized engine on your boat will cause your boat to sit too low in the stern , and that will make it much more susceptible to being swamped by its own wake or that of a passing boat. An overpowered boat is also hard to control.

What about overloading your boat? Overloading your boat, either with too many people or too many supplies, also makes your boat susceptible to swamping.

Even if you are within the maximum allowable weight, make sure that you distribute the load evenly, focusing the weight in the middle of the boat. This will keep your boat stable in the water and help prevent capsizing or swamping.

Finally, remember that in bad weather, you must be extra careful about how much weight you take in your boat. With higher waves, a heavy boat is harder to control and more susceptible to being swamped. Stay safe. Follow the guidelines for load capacity and always adjust for bad weather.

Beware of bad weather! Take much lighter loads in poor weather conditions to ensure boat stability.

Did Bayesian superyacht’s 237ft mast cause it to sink?

B ayesian’s 237ft metal mast may have played a part in the sinking of the superyacht off the coast of Sicily , experts have suggested.

The yacht, named after the mathematical theory Mike Lynch used to make his millions in the tech industry, foundered in the small hours of Monday morning.

Key among potential reasons for the loss of the vessel will be its most striking feature – the aluminium mast.

Four British personnel from the Marine Accident Investigation Branch are on their way to Palermo to carry out a preliminary assessment.

There are also theories that hot overnight temperatures of 27C (80C) could have prompted passengers to leave portholes and windows open – hastening the sinking when the high winds hit.

Launched in 2008 by Perini Navi, Bayesian is one of the 50 largest sailing yachts in the world and her mammoth mast supported a total sail area of almost 32,000 sq ft.

Bayesian had the tallest aluminium mast in the world when it first took to the seas under her former name Salute. The record was overtaken last year when Jeff Bezos, the Amazon billionaire launched his yacht, Koru.

Koru’s masts stretch to 278ft tall according to Boat International magazine.

Tom Sharpe, a former Royal Navy commander and warship captain, said initial reports from survivors and witnesses suggested “that the weather was sufficiently violent to cause her to capsize at anchor”.

Weather reports from Palermo airport, 12 miles west of the yacht, suggest that at about 4am, winds switched from a gentle south-westerly breeze to gusts of 40mph, with temperatures dropping.

Local newspapers have described the weather as a tornado and a waterspout, which is a tornado above water.

The pressure of high winds on the mast could have helped tip the boat over in rough seas, experts have suggested.

Mr Sharpe said capsizing seemed “unlikely” to him given the Bayesian’s size “and that boats like that are designed to survive poor weather – unless something failed at the same time like a valve that let water in and made the whole boat unstable”.

He said it was more likely that the Bayesian had “dragged anchor”. Anchors are designed to lodge on rocks on the seabed, but if the seabed is too soft, or weather is so bad that the anchor is dislodged, then a boat can drag its anchor and drift.

If a boat drifts into an obstruction such as a rock or another boat, this can damage the boat by tearing a hole in its side leading to sinking, Mr Sharpe suggested.

The sea bed off Porticello, the Silician harbour nearest to where Bayesian was moored for the night, consists of a mixture of rocky and muddy areas, according to nautical charts reviewed by The Telegraph.

This means the yacht could have dragged anchor if it had been lowered into a soft, muddy patch of seabed.

A captain of another boat anchored nearby said his vessel was hit by abnormally strong winds on Monday morning.

Karsten Borner said the Sir Robert BP was battered by strong gusts in the early hours of the morning but he managed to stabilise the vessel while anchored by using the engine.

He said as they were doing this, they noticed the Bayesian nearby and manoeuvred to avoid hitting it.

“We managed to keep the ship in position, and after the storm was over, we noticed that the ship behind us was gone,” said Capt Borner.

Mr Sharpe said: “From a seamanship point of view, the other boat (Sir Robert BP) coming up on her main engines and using those to keep position around [her own] anchor is what you should do. Yacht anchors are often not that robust and that is the best way to avoid putting too much strain on it and/or dragging.”

An alternative theory is that the weight of the mast led the Bayesian to capsize.

A yacht industry source told The Times that the vessel sank after the weight of her mast took the hull beyond its “down-flooding angle” – the point at which a boat cannot right itself after swinging at a steep angle – meaning water rushed over the sides into the interior.

“The wind toppled the mast, which fell over the side, causing the boat to heel over and take on water, capsize and sink very quickly,” the source said.

This can occur whether the mast snapped off or not.

Sam Jefferson, editor of Sailing Today, told The Telegraph: “She has a very tall, aluminium mast – I believe it is the second tallest aluminium mast in the world – and that would not have helped.

“Many yachts with big masts have carbon masts instead of aluminium as these save on weight and improve stability and performance.

“Stability was obviously the problem in the extremely strong winds she was experiencing and I’d assume the boat was pinned on its side and could not right before it filled up with water.”

Another superyacht expert who asked not to be named told The Telegraph that the mast could have pulled the Bayesian over into capsizing, although he expressed some scepticism, saying sailing yachts are designed to prevent that from happening.

He said the anchor-dragging theory was also a plausible explanation for why the Bayesian sank.

Typically, crews try to anchor in safe spots that are sheltered away from the wind, they said.

The Bayesian was moored just off Porticello, a few miles east of Palermo. Prevailing winds from the north-east may have robbed the vessel of the shelter offered by the Sicilian coast, which lay to the west.

Dr Lynch was reportedly aboard the vessel. His wife, Angela Bacares, is among those rescued but six others, including four Britons, are still missing.

One person, reportedly the yacht’s chef, died in the incident and his body was recovered by rescuers.

The Bayesian’s last refit was in 2020.

The vessel was listed for rent for up to €195,000 (£166,000) a week, according to online charter websites.

The interior featured six cabins – one master, three doubles and two twin rooms – for up to a dozen guests, with the crew occupying separate quarters.

Fitted out in a Japanese style, the interior was styled by the Remi Tessler design house.

Under her former name Salute, the yacht won the Best Exterior prize at the World Superyacht Awards in 2009, and the Best Interior at the International Superyacht Society Awards in 2008.

A coastguard statement issued on Monday morning said the missing passengers were of “British, American and Canadian nationality”.

Camper & Nicholsons, managers of the Bayesian, confirmed the vessel sank at about 4.30am following “severe weather”.

The Italian Coast Guard is leading search and rescue operations, and said on Monday it had safely recovered 15 individuals.

How did the superyacht Bayesian sink? Experts say weather was just one factor

Divers searching for 6 missing people locate 5 bodies inside wrecked yacht's hull.

Social Sharing

A complicated search effort is underway deep beneath the surface of the Mediterranean Sea, off the coast of Italy, where a superyacht sank early Monday during a fierce storm. 

Dive crews are attempting to enter the wreck of the Bayesian, a 56-metre long British-flagged luxury vessel, which is sitting in some 50 metres of water near the Sicilian fishing village of Porticello.

Fifteen of the 22 passengers and crew members on board were rescued. Divers searching for six people considered missing, including British businessman Mike Lynch, located five bodies inside the yacht's hull on Wednesday, and retrieved four of them from the water.

Searchers previously recovered the body of Recaldo Thomas, the ship's Canadian-Antiguan cook, in the water not far from where the Bayesian sank.

Questions have emerged about why a boat designed to handle severe weather sank so rapidly and whether or not some of its features could've been a factor in its demise. Maritime experts say investigations may, in time, reveal what led to the disaster.

"There needs to be an investigation as to why this happened, what went wrong and, you know, how to prevent it in the future cases," said Simon Boxall, an oceanographer and senior lecturer at the University of Southampton in England.

How did the bayesian sink so quickly.

Grainy footage from closed-circuit cameras on the shore broadcast on the website of the Giornale di Sicilia newspaper showed the Bayesian's majestic mast just before it disappeared. 

Karsten Borner, captain of the Sir Robert Baden Powell, which rescued the survivors who managed to get into a lifeboat, told The Associated Press he was close enough to be able to see the Bayesian as the storm came in.

"A moment later, she was gone," he said.

The survivors told the rescuers they went flat on the water "and were sunk in two minutes."

Boxall said vessels rely on being able to steer and navigate stormy seas, but the Bayesian was anchored and stationary, which likely made it more vulnerable to the storm and, potentially, a waterspout , or mini tornado that creates a whirlwind over the surface of the sea. 

He said it was also dark, meaning "you wouldn't see this sort of very unique event coming towards you."

"It's a freak of nature," Boxall said. "I think the fact that so many have survived, so far, is probably a miracle."

Tom Sharpe, a retired Royal Navy commander and defence commentator, told CBC News the weather was likely not the only issue.

He says it's rare that a weather event like this takes down a boat. 

"There's nearly always a sequence [of events]," he said in an interview from Guildford, England, explaining that everything from safety protocols to the culture on board the vessel needs to be taken into account. 

Was the boat's design part of the problem?

The Bayesian was built in 2008 by Italian luxury yacht maker Perini Navi.

Andrea Ratti, a nautical design professor at Milan Polytechnic, told Reuters that a boat the size of the Bayesian could only sink so rapidly by taking on a huge amount of water. 

He suggested that one or more portholes, windows or other openings may have been broken or smashed open by the waterspout, letting in water. There has also been media speculation that a major hatch might have been inadvertently left open.

Reports have also highlighted that the Bayesian featured a 72-metre mast — one of the tallest in the world. 

Ratti said an unusually tall mast is not by itself an element of vulnerability in a storm. 

A second expert, structural engineer Filippo Mattioni, was also skeptical about the suggestion the boat may have sunk due to a broken mast, which likely would have caused major damage smashing against the hull.

Fire department diver Marco Tilotta told the newspaper Il Messaggero that the wreck was "apparently intact," with "no gashes, no signs of impact." However, only half of the hull is visible to divers.

The Bayesian also had a retractable keel — the fin-like structure under the hull that helps stabilize boats and acts as a counterweight to the mast. 

Both Ratti and Mattioni wondered if the yacht had been anchored with the keel up, reducing the vessel's depth under water and making it less stable. Ratti said strong winds might have caused the boat to start oscillating wildly, "like a pendulum," putting exceptional strain on the mast.

Sharpe pointed out that a mast the size of the Bayesian's is designed for a massive sail, and without that sail raised and catching the wind, the gusts likely would've had a negligible impact on the aluminum pole.

He instead suggested the anchor may have played a pivotal role.

"My kind of working assumption is that she was probably a bit further in at anchor, and it's very likely, in these sort of conditions, that her anchor dragged," he said. 

In such a situation, he said, a crew is better off steering toward the anchor to stabilize the vessel or raising the anchor and heading out to sea to ride out the storm.

"They might have got caught in that middle ground where they're not on a particularly good anchorage, but the anchor is now controlling the bow of the ship."

What caused the extreme weather.

Although Sharpe says the weather is unlikely the sole cause of the sinking, he notes the Mediterranean isn't the calm sea often pictured in travel brochures. 

"It can get pretty nasty," he said.

The type of storm that struck Monday is fuelled by warm water and the Mediterranean is warmer than ever, said Boxall, noting there's been about a three and a half degree increase in the 20-year average temperature.

'The ship behind us was gone,' says captain who rescued yacht passengers

Climatologists say global warming is making such violent and unexpected tempests more frequent. 

Luca Mercalli, president of Italy's meteorological society, said the sea surface temperature around Sicily in the days leading up to the shipwreck was about 30 C. 

"This creates an enormous source of energy that contributes to these storms," he told Reuters.

Superyacht maker's CEO: Bayesian's crew made an 'incredible mistake'

The body of British tech entrepreneur Mike Lynch was recovered Thursday from his family's superyacht that sank off the coast of Italy after it encountered a sudden and powerful storm, authorities said.

After four bodies were recovered from the wreck Wednesday, Lynch's 18-year-old daughter, Hannah, remains the only person unaccounted for, Massimo Mariani, of Italy's interior ministry, told Reuters. Her body may have been swept out to sea, Mariani said.

It could take divers more time to find her body because of the difficulties of accessing the sunken ship more than 160 feet down, said Luca Cari, a fire brigade spokesperson. Rescuers faced a challenging task in scouring extremely deep and narrow spaces around the boat.

Giovanni Costantino, the CEO of Italian ship manufacturer Perini, which made the ship in 2008, told Reuters on Thursday, "The boat suffered a series of indescribable, unreasonable errors."

He said the crew made an "incredible mistake" in not preparing for the storm, even though it was announced in a shipping forecast earlier. "This is the mistake that cries out for vengeance," he said.

Lynch, 59, was best known as the co-founder of Britain’s largest enterprise software, Autonomy, which was sold to Hewlett-Packard in 2011. He had invited his friends on the yacht to celebrate his acquittal in June of fraud charges related to the sale of Autonomy.

The Bayesian, a 184-feet-long British-registered sailboat, went down just before sunrise Monday off the coast of Porticello, near Palermo, where it was anchored when a strong storm swept across the area. Of the 22 passengers and crew members on board, 15, including Lynch's wife, Angela Bacares, were pulled from the water Monday, and several were hospitalized. Divers then recovered the body of Ricardo Thomas, the yacht's chef, near the ship.

Who were among the missing?

An exhaustive search ensued for six missing people: Lynch and his daughter; Judy and Jonathan Bloomer, a non-executive chair of Morgan Stanley International; and Clifford Chance lawyer Chris Morvillo and his wife, Neda Morvillo.

Jonathan Bloomer was a character witness at Lynch’s fraud trial, and Chris Morvillo, an American citizen, was part of the team that represented Lynch.

Hannah, the younger of Lynch's two daughters, was preparing to study English literature at Oxford University, according to the Sunday Times.

Investigation opened into the tragedy

Local prosecutors have opened an investigation into the disaster and will hold a press conference on Saturday.

Costantino said there were no errors in the ship's construction or design. "It went down because it took on water. From where, the investigators will tell," he said.

The ship, owned by Lynch's wife, Bacares, was constructed in accordance with international maritime standards and commercially certified by the U.K.'s Maritime and Coastguard Agency, according to Matthew Schanck, chairman of the Maritime Search and Rescue Council. It was refitted for the second time in 2020.

Experts have pointed to  a waterspout, a tornado over the water that can travel up to 120 mph, that formed during the storm, as well as the weight of the ship's mast, one of the largest in the world, as possible factors in its sinking.

Yacht Sank in Sicily Due to ‘Endless Chain of Errors,' Ship Maker's Owner Speculates: ‘Everything Was Predictable’

"A series of activities should have been done to avoid finding oneself in that situation," argues Giovanni Costantino, who owns the firm that built the vessel in 2008

• Giovanni Costantino — who is the CEO of The Italian Sea Group, the company that now owns Perini Navi, which built the  Bayesian  in 2008 — blames an "endless chain of errors" for the luxury yacht’s sinking on Monday, Aug. 19
• "Everything was predictable. I have the weather charts in front of me here," Constantino told Italian newspaper  Corriere della Sera  of the storm the boat was caught in
• "An unsinkable ship but from the crew an endless chain of errors," the CEO claimed to the outlet

The sinking of the luxury Bayesian  yacht off the coast of Sicily this week  resulted from an "endless chain of errors" by the crew, the ship maker's CEO is speculating.

"This episode sounds like an unbelievable story, both technically and as a fact," Giovanni Costantino — who leads The Italian Sea Group, the company that now owns Perini Navi, which built the  Bayesian  in 2008 — said,  according to CNN .

While speaking to  Italian newspaper  Corriere della Sera , Costantino said he believes those on board should not have been in their cabins, as he claims they were, when the Bayesian sank in the early hours of Monday, Aug. 19. 

Many details of why the yacht went into the water so quickly remain unclear and it's not yet known what the passengers and crew were doing before tragedy struck.

The 183-foot British vessel sank around 5 a.m. local time on Monday after a "violent storm" while near Porticello, the Italian coast guard said in a statement that was previously obtained by PEOPLE.

"Everything that has been done reveals a very long sum of errors. The people should not have been in the cabins, the boat should not have been at anchor. And then why didn't the crew know about the incoming disturbance?" Costantino said in his interview, translated from Italian.

"The passengers reported an absurd thing, namely that the storm came unexpected, suddenly. It's not true. Everything was predictable. I have the weather charts in front of me here. Nothing came suddenly ... Ask yourself, why was no fisherman from Porticello out that night? A fisherman reads the weather conditions and a ship doesn't? The disturbance was fully readable in all the weather charts. One could not not know," he argued.

"An unsinkable ship but from the crew an endless chain of errors," the CEO asserted.

The coast guard has said 22 people were aboard the  Bayesian  when it sank — 12 passengers and 10 crew — and that 15 of those were subsequently rescued.

The body of the yacht's chef, Recaldo Thomas, was recovered nearby.

Costantino's comments came as it was reported that five bodies had been found in the search for the missing six people as of Wednesday, Aug. 21, a source close to the rescue operations confirmed to PEOPLE. Authorities have said that their work is ongoing. 

An Italian government official, Massimo Mariani, reportedly named one of the dead as British tech tycoon Mike Lynch . The other bodies have not yet been publicly identified by authorities. 

Lynch was celebrating with family and friends on the yacht following his acquittal in a fraud trial in June, PEOPLE previously reported.

Costantino offered his view of how the tragedy could have been avoided: "To begin with, in a weather alert situation it was inappropriate to have, as I read, a party. Not that evening. The hull and deck needed to be secured by closing all doors and hatches, after putting the guests at the ship's meeting point as per emergency procedure. Then start the engines and pull up the anchor or release it automatically, put the bow to the wind and lower the keel.

"The next morning they would have departed with zero damage."

When discussing whether the crew were at fault, Costantino reiterated to the Italian outlet that he believes "errors were made."

"A series of activities should have been done to avoid finding oneself in that situation," he said. "I as the ship's captain would have moved, but even if for some reason I had to stay there, I would have managed those weather conditions which then, let's face it, weren't so crazy."

Costantino contended that there would have been "a zero risk if the correct maneuvers had been made and if situations that compromised the ship's stability had not occurred," adding to the newspaper that reports that the boat went down in seconds is "nonsense." He believes the yacht would have "went down" after water "started to enter" within "six minutes."

The remaining missing  Bayesian  passengers are Lynch's daughter Hannah as well as Chairman of Morgan Stanley International  Jonathan Bloomer, his wife, Judy , and New York City-based lawyer  Christopher Morvillo and his wife, Neda , sources have said.

Lynch's wife, Angela Bacares, was among those rescued, PEOPLE previously reported.
