A sail-propulsion element comprises a mast (3), an inflatable sail (1) consisting essentially of two substantially fluidtight adjacent surfaces (4a, 4b) joined together along their periphery, thus forming between them at least one cavity closed around the mast (3), at least one air conduit positioned between the inside and the outside of the cavity, at least one means for injecting air into said cavity, the sail once inflated having a profile that remains permanently symmetrical, irrespective of the movement of said propulsion element, or of the direction or strength of the wind, a headboard, and a sail. The sail comprises a plurality of cells (5) in the direction of the span of the sail, each cell (5) extending from the leading edge (6) to the trailing edge (7), said cells (5) being spaced apart by ribs made of a first soft material.
