A hydroplaning wing sailing craft comprising a single buoyant hull having mounted transversely across the hull a hydroplaning wing having forward sweep and inverted gull wing shape. The wing having a positive angle of incidence providing hydroplaning lift and buoyancy to counteract the heeling moment and thrust of the sail. Mounted atop the hull and the wing is a high aspect ratio sailing rig. Mounted to the stern of the hull is a biaxial control system permitting simultaneous control of the direction in which the craft moves as well as the pitch attitude of the hull and thereby the angle of attack of the hydroplaning wing.

A hydroplaning winged sailing craft having a hydroplaning wing structure and a sailing rig means for producing a heeling moment and forward thrust to the craft comprising a buoyant hull structure, the hydroplaning wing structure being mounted with a negative dihedral transversely to the longitudinal axis of said hull, the wing structure having a forward sweep thereto toward the bow of the hull structure with respect to the longitudinal axis of the hull, the outermost portions of the wing diverging upwardly with a positive dihedral in a gentle curve from the lateral plane which extends outwardly from the longitudinal axis of the hull, the lowest part of the wing on each side of the craft being above the water-load-line of the craft when the craft is levelled about its longitudinal axis, the wing having a positive angle of incidence to provide hydroplaning lift when the craft moves forward under thrust, means for providing positive control of the helm of the craft\s direction of movement, of pitch attitude and of angle of attack of the hydroplaning wing.
