If you want to see Portsmouth Harbor, its two lighthouses, a US Navy submarine base, tugboats, and many other memorable sights from the water, book a private charter cruise with one of our two boats. Two local USCG-licensed captains who have known the area for decades will take you around the Piscataqua River (one of the fastest in the world), New Castle, Kittery, Maine, and even up into the Great Bay Estuary.
