Rust on a mooring chain - New (2001) mushroom anchor, chain and float ;
never out of the water. I pulled the top 5 feet of chain up through the
mooring float and noticed perhaps a 1/16 inch of scale rust on many links.
I had assumed most rust was due to chains coming out of the water for the
winter and sitting in boat yards.Is this due to galvanic action in my
mooring field ? Would some zinc on the chain help ?
