   The use of copper sheathing was first suggested by Charles Perry in 1708, though it was rejected by the Navy Board on grounds of high cost and perceived maintenance difficulties. The first experiments with copper sheathing were made in the late 1750s: the bottoms and sides of several ships' keels and false keels were sheathed with copper plates ...

6. Cathodic protection - Wikipedia

   en.wikipedia.org/wiki/Cathodic_protection

   Sacrificial anodes made from iron attached to the copper sheath of the hull below the waterline dramatically reduced the corrosion rate of the copper. However, a side effect of cathodic protection was the increase in marine growth. Usually, copper when corroding releases copper ions which have an anti-fouling effect.

7. Sea chest (nautical) - Wikipedia

   en.wikipedia.org/wiki/Sea_chest_(nautical)

   Control strategies include coating all surfaces with an antifoulant such as copper-based epoxy paint or hot-dip galvanizing. Periodic inspection and replacement of grates and screens also reduces the risk. Increasing the size of the sea chests by 20% to 30% may delay the onset of serious problems that could force an engine shutdown.
