Kiteski

A wind powered system utilizes a free-flying airfoil tethered to a conveyance device such as a water ski, a skegged hull slab or a wheeled land vehicle which either defines or inherently has tracking means defining a preferred traverse vector across an underlying surface. The tractive force of the airfoil is applied at the center of lateral resistance of the conveyance device such that there is no destabilizing moment caused by the airfoil, thereby removing an artificial limit on the sail area that is imposed upon fixed mast sailing craft. A control bar provides a mount for a tether reel which enables the conveyance device, when same is a kite, to be launched from the water without requiring the assistance of a boat.
