ABSTRACT:
A laterally extending hydrofoil wing is supported in pendulum fashion in a cutout section of a planar keel of a sailing vessel. The pendulum support, in combination with the distribution of mass in the swing wing attempts to maintain the plane of the wing, which is under the surface of a body of water in a position parallel to the surface of a body of water regardless of any rolling or heeling of the vessel. The wing is canted or tilted downwardly into the water in the fore direction of the vessel to plane deeper into the water. When the vessel attempts to roll about its fore and aft axis from its original upright position, the flow of water acting on the canted wing develops a large downward force on the wing and on the keel from which the wing is suspended. The downward force attempts to rotate the keel of the vessel about its fore and aft axis to restore the vessel to its upright position.
