This adjective 'Copper-bottomed' described ships that were fitted with copper plating on the underside of their hulls in the 18th century. The copper-bottoming process was first used on ships of the British Navy in 1761 to defend their wooden planking against attack by Teredo worms a.k.a. Shipworms (actually a type of bivalve clam), and to reduce infestations by barnacles. The method was successful in protecting ships' timbers and in increasing speed and manoeuvrability and soon became widely used.
