Which outcome occurred aboard wooden sailing ships when galvanic corrosion contacted iron fastenings near the waterline?

💡 Explanation

When iron fastenings contacted copper sheathing underwater, galvanic corrosion accelerated the iron's oxidation because of the electrochemical potential difference creating rust and weakening iron. Therefore structural weakening resulted, rather than inaccurate compass readings, barnacle adhesion, or methane release, all requiring unrelated mechanisms.
