Where boats run for black sea bass fishing out of Newburyport
Black sea bass fishing out of Newburyport centers on the rocks around Plum Island, with Jeffreys Ledge at 160 ft as the named offshore ground within reach. Every trip starts at the Merrimack River mouth, and the details of the bar, the ramps and the port itself are in the Newburyport port guide. This page covers where boats run, the grounds, how the fishing is done and who does it. It offers numbers to help you decide where to look, but it can’t promise fish. The wider picture is in the black sea bass fishing in the Atlantic Northeast and the Atlantic Northeast fishing guide.

Boats leave through the Merrimack River mouth. Joppa Flat sits at 5 ft on the Newburyport side, and Salisbury Flat sits at 7 ft. Both are landmarks on the way out rather than places to fish.
