A galvanic isolator is essential as far as I am concerned (also Great Lakes). Mostly because of questionable wiring at many marinas, and certain boaters who do their own on-board wiring and have no clue as to what they are doing.
The galvanic isolator is cheap insurance to protect your boat from other boaters.
