I have a 1980 Catalina 30. These boats have two small winches mounted on the mast, one on each side, about 3 feet above the deck. These winches are used for the main and jib halyards. Raising these sails would be much simplified if I could replace the winches with the newer, self-tailing type. Does anyone know if self-tailing winches will work properly if mounted horizontally?Bob BollerBenicia, CA
