Abstract
A multi-hulled vessel () configured as a trimaran. The multi-hulled vessel () comprises a main hull () and at least one outer hull () to each side of the main hull. The multi-hulled vessel () is provided with motion control means () for providing damping to wave-induced motion, thereby offering ride control. The motion control means () comprises a forward motion damping device () disposed adjacent the bow () of the main hull (), and two aft dampening devices () disposed one adjacent the stern () of each side hull (). With this arrangement, one of the motion damping devices () is located at or near each apex of a notional triangular envelope () of the vessel (). Each motion damping device () is configured to resist wave-induced motion of the multi-hulled vessel () and thereby provide a damping effect. Each motion damping device () may comprise an underwater hydrofoil (), although other damping arrangements are possible.
