Abstract:
A monohull sailing vessel (102, 202, 402, and/or 502) having a lifting hydrofoil (104 and/or 204) having a stowed position and a deployed position in which the hydrofoil extends outward of a leeward side of the hull (138). The hydrofoil may have an aspect ratio greater than 2.5:1, may be oriented at an angle of attack between 2 and 6 degrees, and may be oriented at a mean angle (124) of between 5 and 20 degrees to horizontal. The hydrofoil may have a projected area adapted provide a righting moment and a lifting force for partially but not fully lifting the vessel out of the water. The hydrofoil may have an exposed span (112) that is greater than about 7% of a height of the tallest mast (134). The vessel may include an actuation assembly (128, 228, 308, and/or 316) for moving the hydrofoil between the stowed and deployed positions.
