The technical aspects of two types of advanced marine vehicles, Air Cavity Ship and Wing-In-Ground, are considered for future use in transoceanic transportation. Both concepts utilize the air medium to improve technical and economic characteristics of transportation means. The air is supplied under the bottom hull sections of the Air Cavity Ship, reducing the overall wetted surface and consequently hydrodynamic drag. A contact with water is completely eliminated in the case of the Wing-in-Ground, which moves above the water. This results in enhancing the lift-drag ratio in comparison with a flight in the open air. The principles, experience, and research opportunities on the way to make these concepts applicable for transportation are discussed.
