ABSTRACT:
A method of protecting a hull of a marine craft from adhesion of marine growths and inorganic deposits includes a step of applying protective covering sheets to the hull in a pattern that provides substantially complete coverage of at least the portion of the external surface that is submerged during normal use. The sheets have an outer surface consisting essentially of a polymer such as PTFE that resists adhesion of marine growths and inorganic deposits, and an inner surface comprising a water-resistant adhesive effective to secure the sheets to the outer hull surface and prevent the sheets from coming off. The invention further provides a boat hull or other outdoor structure or vehicle that is protected with sheets according to the described method.
