A double-ended two hull sailing vessel has a main hull and an auxiliary hull, where the distance between the auxiliary hull and the main hull can be varied for controlling heel. The mast is supported on a curved track for varying the angle of the mast relative to the water surface to control the upward lifting force of wind on the vessel to assist in maintaining both hulls level with minimum wetted surface area. A rudder/airfoil assembly is provided at each end of the main hull for providing a lifting force to the forward end of the vessel and for steering the vessel. A control system is provided so that only one of the rudders is in the water and for controlling the orientation of the rudder that is in the water.

A multi-hull sailing vessel comprising: (a) a hull structure comprising: (i) a main hull; (ii) an auxiliary hull; and (iii) connecting arms connecting the auxiliary hull to the main hull; (b) a linear track on each connecting arm, the auxiliary hull being movably mounted on the tracks; (c) means for moving the auxiliary hull along the linear tracks for changing the distance between the main hull and the auxiliary hull; (d) a mast for supporting a sail, the mast having a base; (e) a mast mounting track on the main hull on which the base of the mast is slideably and pivotally mounted for varying the angle of the mast relative to the water surface to control the upward lifting force of wind on the vessel; (f) rigging for moving the mast along the mast mounting track; and (g) a strut supporting the mast, the strut being moveably mounted to the mast and movably supported by the hull structure so the mast can slide and pivot, the base of the strut being laterally spaced apart from the main hull.
