Optimising Hull Lines for Performance
The hull lines of the new 8.5m Sports Cat Design 256 Mad Max , Previously Carbon Copy . She was designed in 1997 but she's the current (2016) title holder of the Australian Multihull Chamionships (2 successive years) and the fastest inshore racing boat in Australian waters.
Trimaran Hull Performance
Recent tests (2009) on a small prototype trimaran with this Box-hull form and flat bottom, demonstrated that performance can be surprisingly good and some of what is lost through increased wetted surface is indeed made up by the slimmer form. While this may not be true at low speeds (below say 4 kt), the flat of bottom may give enough dynamic ...

Trimaran
USA-17—a 90-foot-long (27 m) trimaran, type BOR90. A traditional paraw double-outrigger sailboat from the Philippines. A trimaran (or double-outrigger) is a multihull boat that comprises a main hull and two smaller outrigger hulls (or "floats") which are attached to the main hull with lateral beams. Most modern trimarans are sailing yachts designed for recreation or racing; others are ...
Trimaran Design Planning
As noted above, the Froude Speed/Length ratio is very significant in boat design. Most descriptions and findings re hull resistance are directly related to it. For example it has been shown that a displacement hull creates a wave equal to its length at a S/L ratio of 1.34 and at that point, there's such a hump in the resistant curve that most ...
Catamaran Hull Design
Typically this will be 8-10:1 for a slow cruising catamaran (or the main hull of most trimarans), 12-14:1 for a performance cruiser and 20:1 for an extreme racer. ... The most important catamaran design hull shape factor, is the Prismatic Coefficient (Cp). This is a measure of the fullness of the ends of the hull.

Then the design of the alternative hull forms of a 120 m WL L fast RoRo Trimaran Dinav1 of medium size capacity (800 passengers and 240 cars), featuring round bilge main hull and in-board ...
WHY HULL SHAPES MATTER
A fat hull will have high form drag. A hull too skinny will have higher drag from skin friction. We want asymmetric water planes and a reasonably flat rocker to minimise pitching. A fine entry will minimise slamming in short steep waves and throw less spray. A flat run aft in cross section will promote planing or semi planing at speed.

The Illustrated Guide To Boat Hull Types (11 Examples)
Trimaran Hull. I think trimarans are incredibly cool, and especially the second type. There are two types of trimarans: ... Most boats nowadays use some sort of v-hull or hybrid design, like a semi-displacement hull; especially larger boats. So not a lot of boats have a real flat bottom. However, we do call a lot of boats flat-bottomed. ...
trimaran hull shapes
Waterline beam is 20". draft 16". The hull shape is a fine oval at the bow, becoming egg-shaped, then becoming a 6" flat aft. With high buoyancy in the stern of the main hull and in the bows of the ammas, the pitch-damping can be felt through the seat of the pants and works very well.
PDF Considerations of Cross-deck Structural Design of Trimaran Vessels
The benefits of the trimaran hull form have been studied extensively over the past several years at the University College London (UCL) [1]. In 2000 the RV TRITON, Figure 1 below, a trimaran demonstrator project for the United Kingdom's Royal Navy, was launched to test the trimaran hull form [2]. Figure 1 - RV Triton [2]
40' Cruising Trimaran
Antrim 40 Cruising Trimaran. Hull Design. Hull is composite sandwich construction with kevlar and carbon fiber reinforcements in selected areas. The main hull features an above water chine, which has proven very effective at shedding water. The amas feature high reserve buoyancy and well-rounded decks to for quick water shedding.
16 Best Trimarans For Sailing Around The World (And a Few For
These smaller outrigger hulls are attached to the main hull using beams. While trimarans have a rich history dating back nearly four millennia, these types of sailboats have only gained popularity in the late 1900s and early 2000s. ... The Multi 23 trimaran has a contemporary design, featuring a vinyl ester and PVC foam core construction. The ...

Why You Want a Trimaran: Pros and Cons of a Trimaran
The trimaran separates these two design requirements. In a trimaran, the central hull provides most of the ship buoyancy (90-95% usually). It does this with a long, narrow hull. And then the outer hulls, called amas, provide the stability. This arrangement allows incredible flexibility in the hull design. Due to the wide separation between ...
Using catamaran hulls to make a trimaran
Place the widest one with most volume in the center. Obviously, if you kept the hull in this level position, your trimaran would be dragging 3 hulls through the water with far more drag than for a catamaran. So you need to lower the central hull, so that it will support your 900 lbs .. requiring 14 cu.ft volume under the waterline.
From Catamaran to Trimaran
FROM CATAMARAN TO TRIMARAN. 09.05.2024 Design. In my previous article (see "M-K" No. 12-2019 and 1-2020 ) I talked about the experience of building and operating a collapsible planing catamaran of the Craig Cat type. Such a craft can be equipped with a 12-15 hp motor. and a crew of two people go on plane and joyfully move at a speed of 30 ...
Numerical Research on a T-Foil Control Method for Trimarans ...
The control of the T-foil requires two elements, the prediction of the force relationship during the ship's motion and the design of the control method. Regarding the former, research on trimaran hydrodynamic performance has been greatly aided by the development of CFD (computational fluid dynamics) technology in recent years.
