Lot 4 Porcupine Lane, Westport Island, ME, Maine 04578. Deep waterfront lot of 2.2 acres with 300' of frontage on the Sheepscot River on Westport Island. Close to open ocean, yet not too far from all the amenities the mid-coast has to offer. Rum Cove is a well designed 27 lot subdivision with over 90 acres of common land including a deep water dock already in place. Very private and ready for your vision!
