ABSTRACT:
A device for righting a windsurfer sail and mast that has free fallen along one of a plurality of vertical planes upon release is described. A pulley is attached to a strap which in turn is attached to the mast located approximately half way between the base and the top of the mast. This attaching means allows the pulley to rotate around the mast in a 360 degree arc. A rope is threaded through the pulley where one end contains a loop which is attached to a harness which is worn by the person sailing the windsurfer while the other end contains spherical members attached at even intervals to provide a better grip on the rope. When the sail and mast are released and free fall into the water, pulling on the rope, when properly attached to the person sailing the windsurfer, will right the sail and mast with a 2 to 1 mechanical advantage.
