You may also consider using a metal through hull
and valve without bonding it to the grounding plate. Obviously there will be some normal stray current
that will induce corrosion-but at a rate that will exceed the owners lifetime. I too have read and heard of several boats sinking due to the through hulls being blown out by lightning
, and although there are no certainties with how lightning
moves, not having your through hulls bonded goes a long way to solving this problem.
