ABSTRACT:
A method and apparatus for uphauling the sail of a windsurfer is provided. The method and apparatus for uphauling a sail uses the sailor's body weight to uphaul the sail. The apparatus connects between the windsurfer rig and a harness worn by the sailor. The uphaul line includes a means for shortening the length thereof to allow the sailor to adjust the length thereof during the uphaul process. The method includes attaching the uphaul line to the sailor, the sailor leaning in an opposite direction of the sail to use his or her body weight to uphaul the sail. Before the sailor loses his or her balance, the sailor grabs the conventional uphaul and steadies the rig. Then, the sailor moves his or her body forward and shortens the uphaul line. The sailor can then lean back again to continue uphauling the sail.
