Abstract

PURPOSE: To obtain a simple and labor-saving mechanism by furling a rigid sail constructed by several separated pieces to be flexible by a furling shaft provided in a mast for shortening the sail, and on the other hand, unfurling the sail by means of a wire rope connected at the top of the sail.
CONSTITUTION: For unfurling rigid sails 10A and 10B, the rigid sails 10A and 10B that have been furled up in a mast by furling shafts 5A and 5B are respectively unfurled by pulling forces of wire ropes 7A and 7B along yards 2A and 2B as far as the sides of the yards. For shortening these sails, driving parts 6A and 6B are started to rotate the furling shafts 5A and 5B, and the rigid sails 10A and 10B are respectively furled in the mast.
