About This Tour
Guaranteed Sightings! 7 Seas Whale Watch is located in the heart of historic downtown Gloucester, MA and in one of the busiest parts of Gloucester harbor. As soon as you board the Privateer you will be surrounded by the sights and sounds of Gloucester’s working waterfront. You may see fishing boats unloading fish, lobster men baiting and setting their traps, and perhaps even some of our indigenous wildlife such as Harbor seals, Gray seals, and various species of birds. The tour begins with a harbor tour of Gloucester Harbor starting with Cape Pond Ice (which most of you have seen on Wicked Tuna and ends at the Dog Bar Breakwater. A typical trip is anywhere from 3-4 hours but may be extended if the whales move further out for feed. The Privateer IV was built for 300 passengers but we only book to 150 to ensure the comfort and safety of our passengers and is equipped with restrooms, and on-board food Galley and bar.
Final price may vary. Check availability for exact pricing.
