  • Patent number: 5535692
    Abstract: An adjustable sail head tensioning device for tensioning the head and upper leech of a windsurfing sail. The device allows the head and upper leech to twist off in strong winds; provides more power in light winds; and makes the sail easier to handle in strong winds. The head and upper leech is supported partially by an elastic member. When the sail is unloaded, the elastic tensions the upper leech by pulling the leech into the mast. When the sail is exposed to strong winds, the elastic stretches and permits the upper leech to spill off wind, which makes the sail more controllable.
