Rigging for windsurfer board - has symmetrical sail linked to a shortened mast by rotatable spar, controlled by a steering bow

摘要

The mast (1) is linked to the board (3) by a universal joint (2). At the top of the short mast, a boom (6) is linked by an axial coupling (4, 5) at its middle point. The symmetric sail (7) between the spar and the steering bow is tensioned and shaped. The forward end of the steering bow is attached to a steering lever (9), in turn fixed to the mast and a drive control (12).
