The ABYC wants you to ground the incoming AC to protect against the chance that your battery charger gets hit with water and shorts the AC to the DC system. Their rationale is that the short circuit current back through the AC ground wire should be enough to trip your AC breakers. IMHO it would be better to protect against that scenario by using the GFCI, especially if you are using the boat in fresh water.
