We are in the closing stages of purchse for a 1995 SO 37. Lovely boat in good condiction. The surveyor made a few recomendations one of which involved bonding the keel, engine, and skeg - using a 6gauge wire - and tying them all to a "fish" to reduce the electrolysis. Engineering friends of mine say good idea and I will likely poll them for tips, but has anyone on this forum done this?

Hello, I have bonded major components on a power boat in the past before I became enlightened and bought a yacht. The idea is to have all of these elements at the same electrical potential so that when these dissimilar metals are dipped into the salt water ( electrolytic solution) no current will flow through the water. That way the metal will not suffer from pitting. I am guessing the "fish" you refer to is the sacrificial anode so that if current flows from your boat to another boat or wharf, the metal sacrificed is from the replaceable anode and not from your valuable rudder, keel or prop shaft. In short, it is a good idea and costs little.  Happy sailing. Trevor |
