A water-based sailing vehicle that is able to accelerate from rest under wind power, become airborne, and fly above the water. At low speeds, the vehicle performs as a displacement sailboat. At higher speeds, the weight of the vehicle is supported by a combination of hydrodynamic lift from the planing hull and aerodynamic lift from the wings, or by aerodynamic lift alone. The wings are set at a large dihedral angle, so that with one wing-tip float immersed, the horizontal wing provides a lifting force, while the raised wing provides a horizontal side force for sailing, plus some additional lift. The wings and tail have airplane-type control surfaces which give complete control both in the sailing mode and in free flight.

A wind-powered flying boat comprising a fuselage with wings fixedly mounted thereon at a dihedral angle within the range of 10°to 45°, said fuselage defining a hull member for traveling on a surface of water, float members fixedly mounted on the outer tips of said wings in positions so that either wing will assume approximately a horizontal position when its associated float member and said hull member are immersed in bouyant positions in said water, and a hydrofoil fixedly mounted on each of the float members and projecting downward to develop a horizontal side force in opposition to the component of boat motion in the leeward direction when the boat is traveling in or skimming along the surface of said water, each said hydrofoil having its tip inclined inward from the vertical line through its root when its associated wing is horizontal at an angle sufficient so as to reduce the moment arm with respect to the center of gravity of the boat of the side force that the hydrofoil produces, the bottom of each of said members having a forward planing surface terminating in a step for efficient skimming along the surface of the water.
