Having done this many times, my favorite viewing is to launch from the Greasy Pole (Stacy BLVD ramp on Gloucester Harbor), paddle out the west side of the harbor to Magnolia/Kettle Island for a brief stop near low tide, watch the moon rise over the water and light the way back. Unload boats at the boat ramp and park on the BLVD - be mindfull of the signs as some spaces have time limits.
If it is too windy for that route, an alternative is to paddle out the commercial side of Gloucester Harbor, land at the beach just before Dogbar breakwater, and walk up onto the breakwater to watch the moonrise.
Butts in boat: 7 PM
Off the water: 10 PM+ depending on the route
Lighting requirements: you must have a white light accessible and ready to shine at a vessel for safety. Anyone with a light on a post at the stern gets to be the sweep because those lights blind everyone else. Bring a headlamp and warm clothes, especially for Dogbar.
If you have never paddled at night, you are missing out!
