A device for allowing the base of the mast of a multihull sailcraft to be positioned leeward of the top of the mast. It comprises a mast, shroud lines, an arced track whose radius centers at the shroud line attachment to the mast, apparatus for regulating the travel of the base of the mast along the arced track, apparatus for reducing travel friction between the base of the mast and the arced track, and apparatus for allowing the arced track to be rotated around its central vertical axis and locked in position.
A lift generating sail system for multihull sailcraft which comprises: (a) a mast; (b) a number of shroud lines; (c) an arced track; (d) a means of attaching the base of the mast to and guiding the travel of the base of the mast along the arced track; (e) a means of limiting the friction due to travel of the base of the mast along the arced track; (f) an adjustable means of determining the distance that the base of the mast can travel along the arced track away from the midline of the boat; (g) a means of rotating the arced track around its central verti...
