Boston at the end of the dock.

The Freedom Trail passes our gate. The USS Constitution is next door. Across the bridge, the North End is waiting for you.

Inside our protected basin, the pace is a little different. Floating docks, a pool by the water, and a community that feels at home here. Come for an evening or make it your home port.
