Considering you are in fresh water you are putting people at great risk with your 120VAC ground left floating at the dock. If for some reason you lose your ground connection to the dock, any person could become that connection in the event of a fault.

Here's my interpretation of the relevant ABYC standards.
E-11.16.1 Allows, but does not require, a DC grounding system to be installed.
E.11.16.25 If a DC grounding system is installed, it is allowed to be, but not required to be, combined with the lightning protection, cathodic bonding, and static electricity grounding systems.
E.11.5.4.7 Requires the AC system grounding bus to be connected to either the engine negative bus, or the DC main negative bus.E.11.5.7.4 Allows, but does not require, the negative side of the DC system to be connected to be connected to ground.TE-30 Requires that the propulsion electrical system remain isolated from the boat's grounding system.-Tom
