An apparatus includes a marine component or structure having a surface to be exposed to a marine environment during use. A photocatalyst coating is secured to the surface of the marine structure, wherein the photocatalyst coating includes titanium oxide. The marine component or structure is preferably selected from a boat hull, dock post, dock piling, pier, and buoy. A method may be provided for reducing or preventing barnacle attachment to a marine component or structure, including forming a transparent photocatalyst coating on an external surface of the marine structure, wherein the transparent photocatalyst coating includes a titanium oxide, and placing the marine component or structure in service within a marine environment.
