The trimaran:


A trimaran is a multihulled boat consisting of a main hull (vaka) and two smaller outrigger hulls (amas), attached to the main hull with lateral struts (akas). The design and names for the trimaran components are derived from the original proa constructed by native Pacific Islanders.

The first trimarans were built by indigenous Polynesians almost 4,000 years ago, and much of the current terminology is inherited from them. Multihull sailboats (catamarans and trimarans) gained favor during the 1960s and 1970s. Modern recreational trimarans are rooted in the same homebuilt tradition as other multihulls but there are also a number of production models on the market. A number of trimarans in the 19 - 36 foot lengths have been designed over the last 30 years to be accommodated on a road trailer. These include Catri, Farrier, and Corsair folding trimarans and Quorning and Elan Series swing wing trimarans. See also the new, 2005, fully Carbon autoclave build SeaCart 30 [1]. Many sailboat designers have also designed demountable trimarans that are able to be trailered.

The trimaran design is also becoming more widespread as a passenger ferry. In 2005 the 127 metre (417 ft) trimaran "Benchijigua Express" data page was delivered by Austal to Spanish ferry operator Fred.Olsen, S.A. for service in the Canary Islands. Capable of carrying 1280 passengers and 340 cars, or equivalents, at speeds up to 40 knots this boat was the longest aluminum ship in the world at the time of delivery. The trimaran concept has also been considered for modern warships. The RV Triton was commissioned by UK defence research company QinetiQ in 2000. In October 2005, the U.S. Navy commissioned for evaluation the construction of a General Dynamics Littoral Combat Ship (LCS) trimaran data page designed and built by Austal.
