Abstract: Two fixed, tilted-up wings (22), (FIG. 1), (FIG. 5) attached at or above the water line along the aft rails of any monohull sailboat (20) will serve the dual finctions of being an outboard platform for the crew on the windward side and when the boat heels enough to bring the leeward wing to the water, the design presents the wing at the proper entry as an efficient hydrodynanic lifting body planning the surface.
