Apparatus for powering a boat by a kite so as to use wind as a prime mover and without generating significant rolling and yawing moments, having, in combination with the boat, an arm hinged at one extremity to the boat with means for controlling the position of the arm in inclination and in orientation, and provided at its free end with means for holding kite connection lines from the boat to the kite, with the free end serving as a kite-pulling traction point; the controlling means enabling the development of a straight traction line for the kite lines to pass close to the center board of the boat as the inclination of the arm is lowered and raised and the orientation in azimuth is varied with respect to the direction of the kite lines.
