The invention relates to a sail propulsion element comprising: a mast (3); an inflatable or non-inflatable sail (1) consisting essentially of two adjacent surfaces (5) that are substantially leak-tight and linked to each other about the periphery thereof, thereby forming at least one closed cavity between them, said sail comprising an upper portion (6), a lower portion (7), a leading edge (8) and a trailing edge (9), the sail comprising different curves forming bulges over the entire length; an air duct placed between the inside and the outside of the cavity of the sail; 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 the direction or intensity of the wind; a headboard (10) located on the upper portion of the sail; and a sail receptacle (11) located between the leading edge and the trailing edge on the lower portion of the sail. The element according to the invention is characterised in that the mast is placed in front of the aerodynamic centre of thrust of the sail, in that the mast is free to rotate through 360° or fixed, and in that the sail comprises at least one means maintaining a low pressure in the sail.
