A steerable wing-type sail system for a wind powered craft. The system includes first and second secondary airfoils and that are spaced outwardly to the sides of the plane of the main wing, and that are positioned rearwardly of the trailing edge of the wing. The secondary airfoils are selectively pivotable so as to steer the main wing in one direction or the other. The main wing is also provided with a pivoting flap at its trailing edge, which pivots simultaneously with and in the same direction as the secondary airfoils. The secondary airfoils are carr...


What is claimed is: 1. A wing-type sail system, comprising: a substantially rigid main wing-type sail for extending generally in a vertical plane; means for supporting said main wing-type sail for pivoting movement about a substantially vertical axis; first and second secondary airfoils mounted to said main wing-type sail so that said secondary airfoils are spaced outwardly from said plane of said main wing-type sail on opposite sides thereof, said first and second secondary airfoils being located in positions spaced outwardly from sides of said main wi...
