OK, Rick now ya lost me, if I bond to the engine and the negitive side of the battery bank/ charging system is bonded to the engine the potential IS the same because if I then measure voltage between pos an neg on the battery or pos on the battery and say the mast the differance of potential is exactly the same.
Frank. try reading the Boat Owners Mechanical and Electrical Manual
By Nigel Calder
There is are different schools of thought on grounding and bonding and for every 1 person for it there can be 1 against.
Research shows boats with lighting protection are more prone to strikes but suffer less damage because the give a path to ground. boats without suffer less strikes but when they are hit you can usually find them on the bottom.
