ABSTRACT:
A exterior hull coating with drag reducing qualities for use on waterborne vehicles. The coating comprises a water-soluble polymer of high molecular weight in a vehicle, and a diluent, and contains a swelling deferent agent, driers, and pigments. The coating may be applied by the well-known techniques of brush painting rolling, and spraying. The coating ablates in a timed-release fashion into the fluid boundary layer adjacent to the vehicle skin to reduce drag by the reduction of turbulence and the promotion of laminar flow in the boundary layer.
