I'm sorry. the sea wall is bonded to the utility all over the city per the city code I haven't figured that one out, but the city requires it so it would require alot of isolation transformers.
there is an isolation transformer on the boat.
the corrosion is all over the one side of the boat.
The only electrical contact between the hull and the wall is through the water.
the hull is only painted above the prop and the corrosion is under the paint also causing it to bubble.
the hull is not moored conductive. This has been checked and the electrical system has been checked for grounding problems to ensure not connection to the shore power cable ground. As far as we can tell there is no connection to the hull except thru the water
I have an aluminum hell with Zn anodes that is corroding on one side and the keel. the side that is corroding is the side toward the sea wall. I have verified there to be no electrical issue with the DC system (ungrounded) on board. There is also no electrical connection between the grounding...
