Adjustable centre-board for wind-surfer - has pivoted mounting with friction pads to hold desired position and profiled top for foot operation

摘要

The centre-board for the windsurfer is pivotted in a slot in the craft and is held in any selected angle by friction pads on each side of the slot. The top of the board is profiled with cam shapes so that the operator can tilt the board in either direction. The operator has both hands free to grip the sail bar and can trim the centreboard to obtain optimum sailing effect.
