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.
I do have an isolator but you bring up a good point, I have a friend who lives on the water and has repeatedly told me I'm welcomed to stay at his pier. I might give that some consideration. This wouldn't exclusively be based on stray electrical currents, he is on more protected and cleaner water. I would miss my slip neighbors though.
