Why are Coast Guard ships painted white?
Why are Coast Guard ships painted white? Coast Guard ships and their distinct white paint scheme represent maritime rule of law. They are inherently nonthreatening except to poachers in protected waters. There is a long history of U.S. warships enforcing dominion over Pacific lands, but Coast Guard ships send a different and important message.
Why are bottoms of ships red?
Shipbuilders of the early years of shipping would use a copper coating as a biocide, to prevent organotins from sticking on the vessel's hull. That copper coating was responsible for the ship's red color.
