Abstract
Abstract The invention as disclosed provides a mainsail and/or mizzensail furling device for use on sailboats and includes a furling drum mounted on the gooseneck connecting the boom to the mast. An upper masthead holding means is movably mounted relative to the mast and includes a pair of mast engaging flanges. A first pair of substantially longitudinally extending arms are connected to the flanges and maintain a swivel a given distance from the mast. The halyard is connected to the swivel in a convenient fashion, and a second pair of arms are attached in such a way as to lead the halyard from the top of the swivel device at an angle of approximately 45° to the mast, to maintain the flanges substantially parallel to the mast to facilitate raising and lowering the device as well as a snug fit against the mast when the halyard is made taut.
