Astus 24 Cruiser Trimaran
Description.
The Astus 24 is the ideal cruiser trimaran with vacuum infusion-built hull for higher quality and weight reduction. The concave bottom enhances smooth sailing, taking ground is certainly no problem due to the variable draft. The Astus 24 sails stable and upright thanks to the large floats of 1250 L. The floats with telescopic beams can be retracted or extended without dismantling, so that the Astus 24 can be easily transported on a trailer. A special kit* is supplied for moving the floats while the trimaran is in the water. All sail handling can be done from the cockpit, which makes it possible to sail the Astus 24 shorthanded. The cockpit is spacious enough for 6 people. An outboard engine* up to 9 hp can be attached to the engine support. The functional cabin has a V-bed in the front with two extra settee berths. For touring comfort, the Astus 24 can be equipped with the optional cruise pack*, including mattresses, kitchen unit, chemical toilet, bathing ladder, movable table, aft locker with cover, roller reefing system, lazy bag, UV strip on the jib, navigation lights and electric installation. Sports* options include; Aramid Black Technora sails, carbon float beams and carbon rigging.

Astus 24 is a 24 ′ 11 ″ / 7.6 m trimaran sailboat designed by Eric Hanseval and built by Astus Boats starting in 2014.
Rig and Sails
Auxilary power, accomodations, calculations.
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL
Sail Area / Displacement Ratio
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64) 2/3
- SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
- D : Displacement in pounds.
Ballast / Displacement Ratio
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
Displacement / Length Ratio
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
- D: Displacement of the boat in pounds.
- LWL: Waterline length in feet
Comfort Ratio
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )
- D: Displacement of the boat in pounds
- LOA: Length overall in feet
- Beam: Width of boat at the widest point in feet
Capsize Screening Formula
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Beam folded: 2.55 m Area Mainsail : 22 m² Area génoa: 12.6 m² Area: gennaker: 29m² hauteur sous barrot : 1.70 m berths: 4 catégorie C 5 pers catégorie D 7 pers

Astus Boats Are Now Available in the USA!
Jun 27, 2022
It comes with great pleasure that Red Beard Sailing is now the official US dealer for the brand new line of Astus Boats !
Design & History
In 2004 Jean Hubert-Pommois created Astus Boats. When they got started Astus was only making 7 of their first design the 20.1 in their first year. Now, 17 years later, there are over 400 Astus boats sailing all over the world!
Starting in 2015 Astus sought out a refresh in the model range. As a result, Astus hired world renowned naval architect firm, VPLP, to completely rethink and redesign the Astus range from the keel up!
VPLP is a premier naval architecture and yacht design firm based in France. The firm is well known for their pioneering sailboat designs that have broken numerous speed records. Successful racing sailboats from VPLP include Hugo Boss, Groupama 3, and America's Cup winner Oracle. Continuous innovations in hull forms and foil shapes have kept VPLP Design at the top of the leaderboard in the most challenging regattas in the world.
Performance
The new age of Astus Boats has ushered in a new definition of speed for these small portable trimarans. These boats offer exceptional handling and performance in a small and manageable package. These boats offer a few key design points that really make these small trimarans exceptional:
Narrow Hulls: Skinny hulls slice through the water and waves with ease and provide better light wind performance as well as more comfort in poor and choppy conditions. Typically, narrower hulls means you have less buoyancy, but when used in conjunction with the inverted bows, these boats actually boast more buoyancy than your average production trimaran.
Inverted Bows: Hull speed is a mathematical calculation (speed in kn = 1.35 x square root of waterline length). Inverted bows maximize waterline length by making sure the longest part of the boat is the below waterline (BWL) length. This means the Astus boats will be faster in light winds and will get on plane in lower wind speeds than other boats with traditional overhanging bows. In conjunction with the narrow hulls, the Astus trimarans are very comfortable in a chop because they do not hobby horse as much as more common tri's.
Infusion Construction: The infusion method for constructing the Astus trimarans ensure that the hulls are as lightweight as possible. Less weight means that these boats are faster and can carry more weight, safely, than other similar sized trimarans.
Astus is famous for their telescopic carbon beams that allow their boats to be road trailerable. This style of beam offers a number of benefits over competitive folding and swinging style folding systems.
Less Weight: It doesn't take a big imagination to see this obvious advantage. Other folding / portable trimarans have overbuilt fiberglass beams in order to equal the rigidity of a simple carbon tube.
Fewer Moving Parts: The Astus Telescopic Beams are a simple locking pin and slide, no special tools, parts or hardware are required to maintain or operate. Complicated folding systems have many bushings and specific geometry that must be maintained. In addition to all of those extra parts comes lots of hardware that must be checked regularly.
Easier Transport/Storage: Because the telescopic beams slide in a linear way, the bottom of all three hulls remain the bottoms. Unlike the Farrier designed boats, the Astus boats can easily be moored or docked in a monohull slip. This often means finding a slip is easy (shallow water monohull slips are hard to rent for marinas)! In addition to being easier to store in the water, getting a boat back on a trailer touches the bottom of the boat instead of beautiful painted sides gives you a little more wiggle room and less anxiety when launching and retrieving your boat. The beams also allow the boat to require much less height on a trailer which may make all the difference between indoor and outdoor trailer storage in the winter.
Less Intrusive: The Astus beams do not require beam boxes or mounting hardware that intrude on the interior cabin. This is a massive perk on trimarans under 30 feet where space comes at a premium. If you plan to do some weekend cruising with the family, you will very much appreciate the extra storage and sleeping space!
Manufacturing Process
Astus Boats is located in the Morbihan region in northwestern France , just near The Trinité-sur-Mer and the Gulf of Morbihan. It is no wonder they make such amazing sailboats!
Astus boats does everything they can to keep manufacturing and sourcing local, in France. They design and build the molds locally and even source sailmaking and other boat's components from other French manufacturers. In case you aren't aware, France is the sailing-est place on the planet. Keeping the whole boat French means that every Astus is imbued with the spirit and love that the French have for the sport of sailing!
Affordability
Astus has long prided itself in offering quality, performance sailboats at a price that will allow would-be adventure seekers all over the world, from all walks of life, to enjoy the passion and performance that you get with an Astus trimaran.
Without further ado, below are specs and base prices for each Astus model:

Trimaran test : Astus 24: entry-level tri for travelling

Dragonfly 25 vs. Astus 24
The first is French, basic, stripped out and not without spirit… the second is Danish, designed down to the minutest detail and super sharp. Which one to choose? Multihulls World has tested them both for you.
Two folding and trailable trimarans, for great sailing and weekends away from the crowds. Brilliant!
Dragonfly: At first glance, you notice the inverted bows of the floats and the crossed beams… classy!
Astus: A more attractive design - in particular the coachroof - and fine hulls at the waterline: the 24 bears no resemblance to the early Astuses launched nearly ten years ago already!
Dragonfly: On the Danish tri, they have adopted a bilge line which increases towards the back and a noticeable tulip-shape making the cockpit wider. Note the section of the floats, which is wider at the waterline than at the deck.

Their characteristics are similar - even if they both have a few tricks up their sleeves - and so are their intended programs. It’s a question of two folding trimarans (note the idea is that in just a few minutes they are able to slide into the same slip as a monohull, or onto a trailer under the maximum width allowed on the road), designed for fast coastal cruising, short-handed or with the family. And why not try out your racing skills? All that remains to be said is that Astus 24 is the flagship of the Astus fleet, whereas the Dragonfly 25 is the smallest boat in the range! So there’s a difference in the concept of each one: the Astus is a big little trimaran, while the Dragonfly is a little big trimaran… do you follow? You’ll get it: The 24 uses the same formula as its smaller brothers, involving simplicity and ease of handling, while the Dragonfly, with its rotating mast and streamlined beams is playing in a different league. Out on the water you might think the latter much bigger than the former, yet there is only 25cm between them.
Astus: Eric Henseval, the architect, has favored two marked chines. The first keeps the wakes relatively narrow. The second provides for ...
