We have a high quality range of slips to accommodate boats from 16 to 50 feet in length. All slips have electric and water services available, as well as finger piers for easy and convenient boarding.

Porter’s Seneca Marina sits inside the mouth of Seneca Creek near Middle River offering direct access to the Chesapeake Bay. When cruising by boat from our location in Seneca Creek, you can travel as far north as the C&D Canal and the Susquehanna River or as far south as Crisfield, on Maryland’s Eastern Shore, in a day’s cruise.
