Abstract: The invention relates to a trapeze belt or harness (1) for windsurfing or board sailing. A hook (14) is disposed on a carriage member (13) which is laterally displaceable on guide tracks (11, 12) with respect to a holding member constructed as wide spreader bar (7). The guide tracks (11, 12) can form at the same time the spreader bar. The carriage member (13) is held by a return mechanism (17) in its center position. Preferably, the guide tracks (11, 12) are arcuately formed forwardly and upwardly. By this construction the hook (14) is always in the optimum position irrespective of the posture of a user 24, the forces taken up by the trapeze (1) being transmitted in large-area manner to the body without constriction of the chest.
