ABSTRACT:
A sailing craft of the type which includes a floating hull, a mast secured to the hull, a sail mounted on the mast and rudder means, wherein the mast is pivotally mounted with an articulation near but spaced from the base thereof with respect to a substantially horizontal axis, and a pair of mobile fins having variable lift movably mounted, each on a respective one of the port and starboard sides of the hull, and a linkage interconnecting the mast and the mobile fins for actuating the fins such that they act in the water in a manner so as to tend to right the hull under the dynamic action of water on the fins in a direction opposite to the direction in which the mast pivots, and in which the craft would normally heel under the action of the wind to which it is exposed.
