So your saying that if his boat is producing stray current it would not manifest itself as say a current in the water itself? Wouldn't his whole boat become a large galvanic cell if he had potential differences in places under water from his various through hulls/ fittings/ prop etc? Wouldn't electrons flow from one part to another causing pitting and well electrolytic corrosion? I would think boats with currents flowing through them would have associated magnetic fields and there would be currents in the surrounding water that could affect nearby metal. Am not sure I understand why stray current would only arrive through a ground wire and there would be none in the water itself.
