A wind propelled vehicle comprising: (a) an assembly of airfoils fixedly joined; (b) all-moveable rudder and horizontal stabilizer, or suitable substitute, for aerodynamic yaw and pitch control; and (c) pontoons and hydrofoils, skis, skates, runners or wheels. The vehicle is wind-propelled by controlling the angle of the relative wind to produce a sideways lift force on the airfoil assembly and controlling the angle of the pontoons, etc. to use that force to cause forward motion. Airborne operation is achieved by changing the angle of the relative wind to produce an upward lift force on the airfoil assembly. Water rudder is absent. Orientation is always controlled aerodynamically.
