DE3106942A1 - Rig with double sail - Google Patents

Abstract

In conventional rigs, a technical problem stems from the aerodynamic rule that the efficiency of a sail is inferior to the efficiency of a profiled wing. This disadvantage can be avoided by a double sail with an adjustable asymmetric wing profile. To solve the technical problem, a folding square sail is used, which according to Fig. 1 is folded into a double sail (1) in the area of the vertical centre line and encloses the mast (2). Here, the clews (4, 4') of the double sail (1) are connected to the spar of the boom (3), which is attached to the mast (2) in a rigid or articulated manner. When a windward sail is set in a flat or concave manner and a lee sail is set in a convex manner, the double sail (1) serves as an adjustable wing with an asymmetric wing profile. Main use is sailing or windsurfing at maximum speed. <IMAGE>

From a registration dated December 16, 1980, there is an R ^; gg with double so.ft'pl obviously, in which an asymmetrical wing profile is achieved by the laughing lYiuuii of the Liivsege.ls ^ nd bulbous trim of the i.oesi \ o; e ί s. The clews of the double sail are hiorboi attached to the nocicus of two large trees that are connected in an angular manner. The disadvantage here is that the large trees are arranged outside the double sail, which increases the air resistance of the rig.
