ABSTRACT:
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').
