Improvements made to the conventional windsurfing board, with the aid of devices which make possible the propulsion of one or of two boards with the aid of sculls, or their use with the aid of a fixed mast, of one or of two sails held by hand; a board can be equipped with lateral floats (I) equipped with anti-bather fenders (17); this device is made integral with one or with two boards with the aid of bolts (23) screwing into arches incorporated into the board; this applies for boards ex-factory; for current boards, two bolts (4) inserted into the sides of the centre-board well render the board and the device integral, this interconnection being completed by small handles (5) inserted into the hole of the safety end (7); straps (9) can complete the link; the scull pivots are kept at adequate height by long sleeves (II) reinforced by ties (25); the seat (12) can be fixed or sliding; an alternative embodiment allows propulsion without floats. <IMAGE>
