That is discouraging to learn as we are considering relocating to the east coast and the pro's and con's were in a dead heat. Does that prohibition apply to electric grills as well? I have been in west coast marinas that prohibit gas grilling. I don't remember the exact wording, but I infer that it is the prospect of open flames jumping out of a grill, particularly one that is not built in to the boat. In any event, my grill (which is built in and looks like a smaller version of what might be found in a backyard "outdoor kitchen") was not objected to. As a practical matter, it would take close inspection to determine that it was gas and not electric.
It's open flames only so does not pertain to electric grills. Same rules as most communities on apartment and condo complexes. Never had a problem using electric grills.
