<p>The wishbone is removably fixed to the mast (2) of a sailing board. It comprises two arms (10), (11) articulated about the axis of a hinge (5) parallel to the mast and located at the end of the arms, on the mast side. At the remote end of the mast, the arms are interconnected by a detachable holding element (12). Each of the two arms carries a tightening check (8, 9) facing the other one. These two checks grip the mast in an operating position and allow an easy and quick mounting and dismounting of the wishbone on the mast. </p> |
