Abstract: An elevated sailing apparatus that includes one or more wings, tethered to a conveyance, and suspended from beneath a streamlined, lighter-than-air blimp. The wings generate both propulsive and lifting forces from the wind. The propulsive force is used to propel a conveyance. The lifting force prevents the apparatus from being pushed into the water by the propulsive force. The wings use stabilizers to orient them to the oncoming wind and control surfaces to adjust the angle of orientation. A ballast weight provides a vertical reference relative to the blimp, so that the propulsive and lifting forces can be controlled independently. A remote control system allows the degree of lifting force and propulsive force to be controlled from the conveyance. Thus the pilot may tack the apparatus and control its altitude. The use of a streamlined blimp and high aspect-ratio wings allows this elevated sailing apparatus to achieve the low drag-angle necessary for high-speed sailing.
