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.

[ What I claim is:] [1.] A boat pulled along by a kite comprising an arm which is articulated via a first end to the boat, the point through which the kite strings connecting the kite to the boat pull constituting a second end of the arm, the kite being connected to the boat only by said kite string

[ What I claim is:] [1.] A boat pulled along by a kite comprising an arm which is articulated via a first end to the boat, the point through which the kite strings connecting the kite to the boat pull constituting a second end of the arm, the kite being connected to the boat only by said kite strings, comprising means for controlling the inclination of the arm allowing the latter to be lowered with respect to the direction of said kite strings, and a means for controlling the orientation in terms of azimuth of said arm with respect to the direction of the kite strings, said kite stings all passing through the single pulling point which constitutes the second end of said arm, and where in the articulation of said arm consists of a rigid intermediate component which has two perpendicular axes of rotation, the first axis, which is vertical, serving as a connection with the boat, the connected end of the arm being attached to the second axis, said arm and the vertical axis of rotation being coplanar.
