A sail (20) for a sailing vessel (500) includes a leading spar (22), a coplanar trailing spar (24), and a movable spar (28) disposed between the two. A sheath (30) of sail cloth traversely surrounds the three spars forming a flexible double-sided wing-like structure. When the wind (600) blows against sail (20), movable spar (28) is urged toward the leeward side of sail (20), and transforms that side into the curved or long side of an airfoil, thereby creating a push force (54) which propels the sailing vessel (500).
On décrit une voile (20) destinée à une embarcation à voile (500) qui comprend un espar frontal (22), un espar arrière (24) coplanaire et, entre les deux, un espar mobile (28). Une gaine (30) de laize entoure de manière transversale les trois espars formant une structure souple à double face en forme d'aile. Le souffle du vent (600) contre la voile (20) pousse l'espar mobile (28) vers l'extrados de la voile (20) et transforme ce dernier en une face incurvée ou longue d'un profil de voilure. Il se crée ainsi une force de poussée (54) qui propulse l'embarcation à voile (500).
