Welcome Aboard the Privateer IV
Privateer IV in Gloucester Harbor
Since 1983, we have had the privilege of introducing thousands of passengers to the many species of whales and marine wildlife that visit and inhabit the waters just a few miles from our dock in historic Gloucester, Massachusetts. (approx. 50 min drive North from downtown Boston)
Our whale watching tours to Stellwagen Bank National Marine Sanctuary run daily from mid-April to mid-October and are designed to educate, inspire and provide a deeper understanding and appreciation of the fragile marine environment.
7 Seas Whale Watch is a local family business – Three generations of career captains have worked from this very dock for more than 7 decades. We have a love and respect for the marine environment and a passion for providing the best possible customer experience for you and your family.
Browse our website, reserve tickets online, call our sales office (), or use our contact form to ask a question or send a comment. We look forward to seeing you on the water.
What You Could See On Your Whale Watch
The whales and marine wildlife we observe are wild, untrained animals in their natural habitat. It is impossible to predict the quantity, species and behavior of the whales and wildlife that we observe – Each trip is unique. That having been said, the highly productive waters just off the Massachusetts coast often attract a great number and variety of whales and other marine wildlife which is why we have an over 99% sightings record.
