For safety reasons, the ABYC specifications call for the shore power
cord to be grounded to the DC ground which includes the underwater
metal attached to the engine(s).


What safety reason is that? The engine doesn't have any AC-powered
equipment, neither do any of the DC-operated equipments. There's no reason
to AC ground anything not hooked to the AC power line.

Have you got a reference to ABYC about this? I'd like to read what it
says, other than "for safety reasons"....
