Trimaran to the main hull. This allows them to be trailerable and/or to fit in a normal monohull space in a marina. At least six technologies are in use: Although it is possible for a trimaran to capsize, this is less frequent than with monohull boats because of the greater resistance to rolling that the amas offer. Most trimaran designs are considered nearly unsinkable because even when filled with water, the buoyancy of one ama is enough to keep the entire vessel afloat. Because of their stability and safety, special trimarans such as the Challenger have become popular with sailors who
Trimaran hull". The outrigger hulls are "floats". The structures between the main hull and the floats are called the "wings" and the structural portions thereof are "beams"). In cruising trimarans the wings are solid and cabin accommodation extends over them, while in racing trimarans accommodation is limited to the main hull and the wings are open sheets of netting. In comparison to outrigger canoes, trimarans typically feature a sail (or engine) and are not primarily designed to be paddled. Trimarans are typically significantly wider. In addition, trimaran floats are much more buoyant than those of outrigger canoes to support a large
