ABSTRACT:
In a sailing craft, in which the foot of a sail is attached to a yard pivoted on a boom, itself pivoted on the mast, this sail, provided to be of single or double-thickness, preferably comprising a sectioned front edge, restraints are provided for selectively blocking either the yard with respect to the boom, or the boom with respect to the hull of the craft, so that the sail may pivot either on itself or about the mast, as desired.
