ABSTRACT:
A sail maneuverable through the rotation of a rolling and unrolling structure to which the sail is anchored along an anchorage edge. A sheath surrounds the rolling structure and engages the sail at opposite sides along a coupling line spaced from the anchorage edge. The sheath and that intermediate portion of the sail between the coupling line and the anchorage edge being shaped so that when the sail is unrolled the sheath stretches out, retaining the intermediate portion within the end zones unstretched, causing the sail to take a bellying or fat-sail arrangement. At the beginning of rolling, the sail is pulled back into the intermediate portion and progressively also into the end zones, thereby assuming a flat-sail arrangement.
