摘要

The vessel has a single sail (6) supported on a sail board (1). The hull is fitted with a centre plate (2). The plate is hollow and closed with a bung (3) tied to the hull by a chain (4) so that the centre plate can be filled with fresh or sea water. The mast (5) has a boom (7) supporting the sail. The rudder (9) is fitted to the board by the bracket (10). The boom end is formed to the sail board via the sheet (8).
