ABSTRACT:
Improved sailcraft have a plurality of rectangular sails of approximately equal size, each carried on a separate mast that is enveloped by the sail luff. A full-length batten is fitted to the leech of each sail. The leech of each sail may overlap the luff of the adjacent aft sail. Sheets run from each sail leech to starboard and port members of a pantograph moveably carried in an horizontal plane about at the vertical midpoint of the sails. Fore and aft movement of the pantograph members to vary the set of the sails may be linked to the movement of a rudder to provide automatic constant sailing direction relative to wind direction. The sailcraft can be a multihull type in which starboard and port hulls or pontoons are cantilevered to a central mast-supporting section for pivoting between an extended, sailing position and a retracted, transport position.
