I like to think of myself as a moderately smart guy but all the bonding/grounding information on the web has seriously confused me.
I have rewired my boat completely with no major problems or confusion except for bonding. It is a small 26' grp boat with a basic bonding system dating from early 80's when it was built. The bonding system connected an external hull zinc to the copper keel cooler to the engine block. The keel cooler also has a bolt on zinc. The stainless prop shaft/bronze prop w/zinc has a new flex coupling that it didn't have before so is isolated from the engine. The only other underwater part is the stainless rudder and shaft, not bonded but with a zinc.
The boat does not have a full AC system. I do have a permanently mounted hard wired marine battery charger but it is only connected via regular ac extension cord (household type plug). The boat will be kept on a mooring with only rare connection to shorepower.
From what I have read it seems I could remove the bonding wires and just have zincs on underwater metal.
