I have some bronze portholes that were in tropical water for 50 years.
There is very nominal spotting of green in places. More coral than green.
They are Naval Bronze. A Very special alloy.

You might also consider why metal pool fixtures are always stainless,
not brass or zinc like freshwater boat hardware.


You mean cheap bass boat hardware?

Everything on my boat is stainless.
