Galvanic corrosion, opinion please

[charles_reed]

I need some help here.

I am concerned about galvanic corrosion and asked about it at the Boat Show.

What I found was that every single person has a different view.

I talked with Coppercoat, Vetus, Volvo, Mc Duff, Mastervolt, bruntons and others.

I got two diametrically opposing views at Volvo and every possibility on this earth from the others.

So, where to go?

My conclusion is to take every possible precaution and to doubt every solution. Minimise every possible risk.

I moor in a marina, with shore pore most of the time.

I have piles close and a piled wall fifty feet away.

I have a galvanic isolator but can't find a way to test it. An isolating transformer seems perfect.

Any comments from the gathered experts?.

Thanks

Tony

My daughter who is a materials specialist in a school of engineering in a Russell University once had the "UK's acknowledged specialist on galvanic corrosion" working with her. Her summation was that it was a black art - get three specialists on the subject together and they'll end up with n to the n-1 opinions. Based upon those you spoke with you should have had 6 to the power of 5 theories. Perhaps you were spared that because they didn't have a chance to communicate with each other?
