Abstract: A head structure is disclosed which includes a novel deck, bulkhead and overhead coating which prevents moisture, especially corrosive sea water, or salt atmosphere from reaching the underlying deck, bulkhead or overhead even if the surface of the coating is damaged or penetrated. The coating provides an attractive and highly durable surface which is easily cleaned and resists staining or discoloring. The novel coating in connection with the unique head design allows a head to be easily and rapidly cleaned and maintained a daily basis by simple wash-and wipe techniques requiring minimal crew involvement time. This permits crew members to be able to devote more of their time to education and productive endeavors rather than to maintenance. The head has a deck, bulkhead and an overhead, most or all of which are susceptible to corrosion in the salt water environment.
