Hondo, I was just reading today about John Wilkinson "Iron Master" In 1761, the Royal Navy clad the hull of the frigate HMS Alarm with copper sheet to reduce the growth of marine biofouling and prevent attack by the Teredo shipworm.
His Wiki page has info on this under his "copper interests" a really interesting historical figure.
