PURPOSE:To suppress the exfoliation of an air current and to obtain a great life, by attaching slats to each wing end. CONSTITUTION:A fixed sail 2 is fixed at a turning mast 8 via arms 9. The turning mast 8 is connected with a fixed mast 11 via a turning bearing 10 so that it is rotatably supported. A spreading-striking sail apparatus consisting of a vertical rod 13, which is located between the turning mast 8 and the fixed mast 2, ring levers 14, etc. is attached to hinged sails 3, 4. The slats 15 are attached to opposite wing ends of the hinged sails 3, 4 vertically along the hinged sails via slat fixing blocks 16. The salt fixing blocks 16 are attached to the hinged sails 3, 4 with a certain space between them. |
