A retractable-airfoil vessel has surface-effect wings ( 1) that are hinged or otherwise attached extendedly to a vessel ( 3). The surface-effect wings are extendable to a use mode in proximity to a surface of water (5) at sides (2) of the vessel for surface-effect lift of the vessel at elevated speeds. At low speeds when pleasure cruising or fishing, when stopped for water activities or when adjusting to rough waters and storm conditions, the surface-effect wings can provide wide-area buoyance on water at sides of a center of gravity of the vessel. The b...
What is claimed is: 1. A retractable-airfoil vessel comprising: surface-effect wings attached extendedly to sides of a vessel having structure and motorized power for desired marine use; the surface-effect wings each including a bottom surface adapted for riding on air flowing intermediate the bottom surfaces of the surface-effect wings and a surface of water in which the vessel is buoyant and the vessel is traveling forwardly at a speed for causing the air to flow intermediate the bottom surface of the surface-effect wings and the water for achieving s...
