Abstract: A comprehensive System of hoisted, universally compatible, semi-elliptical mainsails and self-tacking headsails. Reducing weight on deck and aloft and fully cockpit-controlled, self-boomed System sails replace cumbersome conventional genoas and rigid booms with self-boomed, overlapping, self-tacking, semi-elliptical headsails and mainsails. Each sail assures optimum sail interface. Synergism between aerodynamic headboard-end plate combinations, integrated alternate energy, and maximum sailing efficiency optimizes convenience, safety and performance. Overlapping Maxjib (26), Non-overlapping Maxjib (28) and self-boomed Maxmain (30) are self-boomed, self-tacking hoisted sails. External-spar Maxmain (32) provides unique new System benefits for boomed mainsail configurations.

Abstract: A versatile multi-component sail system for propelling any wind-propelled vessel at optimum efficiency on all points of sail with a minimum number of sails, with minimum crew effort, and with all sail handling done from the safety of the cockpit, comprising one or a plurality of horizontally deployed in-place semi-elliptical convertible genoa-jibs (22); vertically deployed, semi-elliptical self-tacking jibs (23); and low-profile in-place automatic jib stowage bags (44). The system's integral sails and sail stowage and control means remain in place and are active throughout the sail deployment, navigation and sail recovery cycle. One or all system components may be used as needed to provide a synergistic combination of performance, safety, and convenience to any wind-propelled vessel over the widest possible range of conditions.
