Brothers Rudy and Donald Austin, both former ferry captains, offer boat tours to historic Portsmouth Island. Departing daily from Silver Lake Harbor at the dock shared by the Watermen's Museum, the Austins are excellent guides for local history as well. You will be dropped off at the historic village with a self-guided tour map and have four hours to explore the village and beach area. Ask the Austins for advice about mosquitoes in the village prior to your trip (those wary of bugs but looking for unparalleled beachcombing can elect to skip the village tour). The Austins also run a 60- to 90-minute boat tour of the surrounding islands, a dolphin cruise and a sunset cruise. Regular trips run in spring, summer and fall. Winter trips are on demand. They are also happy to work with special event requests such as school groups, weddings and group charters. Reservations are recommended.
