A wing type sailing yacht is constructed to incorporate the airfoil principle. Such a yacht has a boat hull, a mast, and a sail, including a bow with a bow keel and a stern with a stern keel. Each keel has a buoyancy control fin (9, 10) at its lower end. An outrigger arm (6, 6′) is attached laterally to each side of the hull. The end of each outrigger arm carries a downwardly projecting fin strut which in turn carries a further buoyancy control fin (8, 8′). The buoyancy control fins (9, 10, 8, 8′) form a four-point wing or airfoil type system for producing lift or buoyancy and for maneuverability and stability. The outrigger arms (6, 6′) are built as narrow surface wing type carriers having a negative sweepback. The arms have a predetermined elasticity. A pontoon (12, 12′) is attached to the end of each outrigger arm. The fin struts act as lateral control fins or steering wings (11, 11′).

A wing type sailing yacht, comprising a hull (2), a mast (3a), and a sail (3) carried by said mast, said hull having a bow (5) with a bow keel (13) and a stern (7) with a stern keel (14), said bow keel (13) having first buoyancy control surfaces (9) at its lower end, said stern keel (14) having second buoyancy control surfaces (10) at its lower end, an outrigger arm (6, 6′) attached laterally to each side of said hull (2), an approximately downwardly projecting fin strut (11, 11′) acting as a lateral steering wing at the end of each of said outrigger arms (6, 6′), a third buoyancy control surface (8) at one of said fin struts (11), and a fourth buoyancy control surface (8′) at the other of said fin struts (11′), said first, second, third and fourth buoyancy control surfaces (9, 10, 8, 8′) forming a four-point wing system for producing lift, for steering, and for stabilizing, said outrigger arms (6, 6′) comprising narrow elastic surface wing type carriers having a negative sweepback, pontoons (12, 12′) attached to ends of said wing type carriers (6, 6′), said third and fourth buoyancy control surfaces (8, 8′) and said fin struts (11, 11′) forming together an L-shape, said bow keel (13) having a high speed bow rudder (15) secured to said bow keel (13) below said first buoyancy control surfaces (9) to form a first cross-configuration (13, 9, 15), said stern keel (14) having a high speed stern rudder (16) secured to said stern keel (14) below said second buoyancy control surfaces (10) to form a second cross-configuration (14, 10, 16).
