Abstract
(EN)
Means lor improving the yield or a sail of a sail craft and at the same time to secure the craft against having the bottom turned up after a capsizing. According to the invention a certain amount of buoyancy material (8), which is flexible, is fastened to the uppermost portion of the sail, see fig. 1 and 2, the buoyancy material (8) being shaped such as to form together with the mast (1) and the sail (3) an acceptable airfoil profile, see fig. 2. The buoyancy material (8) has at the same time a volume, which is large enough to keep the sail (3) and the mast (1) floating at the water surface after a capsizing of the craft. In order to make the folding of the sail (3) easier prior to putting it into a sail bag, the buoyancy foam may be split up into a plurality of buoyancy zones (4 and 5) separated by folding zones (6), see fig. 1.

Moyens d"amelioration du rendement d"une voile d"une petite embarcation a voile qui servent aussi a empecher que le bateau ne se retourne apres un chavirage. Une certaine quantite de materiau flottant (8), flexible, est attache a la partie la plus haute de la voile, voir figs. 1 et 2, le materiau flottant (8) ayant une forme telle qu"il forme avec le mat (1) et la voile (3) un profil aerodynamique acceptable, voir fig. 2. Le volume du materiau flottant est suffisamment grand pour que la voile (3) et le mat (1) flottent a la surface de l"eau apres un chavirement de l"embarcation. De maniere a faciliter le pliage de la voile (3) avant de la ranger dans un sac a voiles, la mousse flottante peut etre decoupee en une pluralite de zones flottantes (4 et 5) separees par des zones de pliage (6), voir fig. 1.
