High sail
The high sail (older name: Bermuda sail ) is a sail in the shape of a triangle. The front edge of the sail ( luff ) is attached to the mast , the lower edge ( foot ) is mostly driven with a tree .
The high sail developed from the gaff sail . It differs from him in the absence of the gaff and the triangular shape with a longer luff with the same sail area (see sketch below). This results in aerodynamic advantages, which are due, among other things, to the fact that the large vortex zone that occurs in the gaff sail in the area of the top leech and the gaff is not present in the high sail. For a correspondingly large sail area, however, a higher mast is required.
High sails belong to the group of Schratsegel . They are found in most modern sailing boats today because they are easy to use and well with them against the wind showed up can be.
