M/V Challenger

The M/V Challenger is our smaller, more intimate, single level vessel.  The Challenger is perfect for quieter sailings, scenic transfers to Star Island, and is flexible for private bookings. With an open design and shaded seating, it offers excellent visibility and a comfortable ride through Portsmouth Harbor and out to the Isles of Shoals. While smaller in scale, it retains all the charm of our coastal cruise experience and is frequently used for the outbound portion of our Star Island Day Trips. The Challenger can also be reserved for private charters, with limited availability throughout the season.
