Re: Zinc Or Aluminum Anodes On Mid Chessie
You live in a marina, a galvanic isolator should be your first concern. Far more damage is caused by your neighbor's boat's leaking current than by simple electrolysis in the water.
I say neighbor's boats because that's the way it works out - they are worse for you than your own boat.
I keep my boat at my dock with no other boats within 100's of feet, and I still have a isolator.
Lessons learned are opportunities earned.
