A sail propulsion element comprises a mast (3), an inflatable sail (1) consisting essentially of two substantially fluidtight adjacent surfaces (5) joined together along their periphery, thus forming at least one closed cavity, at least one air conduit positioned between the inside and the outside of the cavity, at least one means for injecting air into the cavity, the sail once inflated having a profile that remains permanently symmetrical, irrespective of the movement of the propulsion element, or of the direction or strength of the wind, a headboard (10), a sail receptacle (11), and at least one guide line (12) positioned in the closed cavity of the sail, for the maneuvers of hoisting and dropping the sail, the guide line extending from a leading edge (8) to a trailing edge (9) of the sail, passing through the headboard (10) and the sail receptacle (11).
