DISPOSITION ARCHITECTURALE PERMETTANT D'AUGMENTER DE LA STABILITE DES VOILIERS DE TYPE MONOCOQUE PAR DES FOILS

摘要

The appendage has a main function for generating a vertical lift for a sail boat when the sail boat navigates, where the appendage is disposed under wind of the sailboat for controlling adjustment torque for the sail boat and is retractable alternatively from one or two sides of the sail boat. The adjustment torque is varied depending on the speed of the sail boat and an immersed surface of foil of the appendage.
