Device for trimming the sail of a windsurfing board

摘要

A device for trimming the sail of a windsurfing board by means of a trimming sheet arranged between the rear end fitting of a wishbone and the clew of the sail is described. In this arrangement, the trimming sheet is functionally placed in the wishbone in order to vary its length, so that the tensile and compressive forces of the sail are directly transmitted via the trimming sheet to the rigid wishbone tubes. A wishbone is thus created which is variable in its length and automatically adapts itself to the size of the sail. <IMAGE>
