ABSTRACT:
The device trains a user of a windsurfer board, which comprises a mill (resembling a surfboard) having a central longitudinal daggerboard (similar to a keel) and a short skeg at the stern and has a mast pivoted to the board forward of the keel carrying a sail, the tack of the sail being attached to a curved boom extending from the mast. In water, the hull pivots around the daggerboard and the skeg functions as a drag on the pivoting. The training device simulates this effect on land. The hull (with daggerboard removed) is fastened to a table supported by a vertical shaft journalled in a base supported above the ground. The shaft has a radial crank connected to two shock absorbers which are also supported by the base. The shock absorbers simulate the friction of the hull and the drag of the skeg in water.
