I don't have a subscription to the NFCs. Does "NFPA 302, Fire Protection Standard for Pleasure and Commercial Motor Craft 1998 Edition" address the on board wiring of the boats themselves? The absence of a pole in the transfer switch to transfer the neutral from the on board source of AC to the shore line is the source of the problem. The on board Grounded Conductor and the on board Equipment Grounding Conductor are bonded together at the source. If the Grounded Conductor does not transfer then the neutral currents from the boats will flow over the EGCs and through the water causing stray currents and voltage gradients everywhere.
