ABSTRACT:
Sailboard comprising a sail assembly and a floatboard (2) supporting the sail assembly. The sail assembly comprises two wings (4, 5) in relatively displaced relation to each other, the two wings having substantially parallel leading edges (6, 7), the two wings being connected together by a rigid supporting frame ensuring a constant relative positioning of the wings. One (7) of those leading edges has an end (7a) which is removably and pivotably laid upon the floatboard (2), thus permitting the user to move the sail assembly during navigation between a position where the end (7a) of that one leading edge is pivotably laid upon the floatboard and a position where the sail assembly is dissociated from the floatboard and maintained by the user in a substantially horizontal position to produce a sustentation effect.
