<p>The wishbone is for a windsurfing board. The main sail supports (101) have, on all or part of their length, one or more holes (102) and can dip partly or vertically in the water. The wind surfer can move the mast-sail-wishbone assembly to the wind direction. The holes are circular, or rectangular and are along the sail support planes. When lifting the mast-sail-wishbone assembly there is no direct wind action on the sail.</p> |
