ABSTRACT:
A multi-hulled sailing vessel is provided with a pair of aileron foils that are mounted outboard from each of two sponsons that are rigidly joined to a central main hull. The aileron foils are rotatable about axes that are inclined toward each other when deployed. Each of the sponsons is provided with a mast carrying a sail. The masts are coupled together by a pair of transverse stabilizing struts. The masts are each supported by separate shroud systems. The vessel is equipped with load sensing and foil control means coupled to at least some of the shrouds and to the aileron foils so as to rotate the aileron foils about their axes responsive to loads in the shrouds. A rudder at the rear of the central main hull is provided with a transversely mounted elevator foil which is also rotated about an axis transverse to the rudder responsive to loads in the shrouds. The foils and the rudder are mounted for rotation relative to the sponsons and the central main hull and can be brought entirely out of the water.
