2100056 9212044 PCTABS00014 A water craft having a central hull located between two outrigged floats wherein each float is joined by a bridge member to the hull at a root position extending parallel to the longitudinal axis of the hull the centre of the root position lying behind the longitudinal mid-point of the hull; and each float is located relative to the hull so that its centre of buoyancy is forward of the root position. Each float contributes less than 20 % of the buyonacy of the combined floats and hull. Each float or an extension thereof is equipped with a separate hydrofoil surface which is located on the float at a position behind the centre of buoyancy of the float. Preferably the craft is equipped with at least one sail to provide propulsion such that the, or at least one, sail is supported by way of a luff spar mounted on the upper end of a bipod mast whose lower end is supported on the hull. The lower end of the bipod is pivotably mounted on the hull to enable the bipod, luff spar and the sail to be lowered and raised between an erected working position and a lowered stowed position on or adjacent the hull.
