What to Expect on the Day
Depart Long Wharf
Both tours depart from Long Wharf at the foot of State Street in downtown Boston — one of the most historically significant wharves in America. Walk straight from the MBTA Aquarium station (Blue Line). The New England Aquarium is next door. Allow 15–20 minutes before departure for boarding.
Boston Harbor transit
The first 20–30 minutes pass through the inner and outer Boston Harbor, past the Boston Harbor Islands State Park. Cormorants, great black-backed gulls, and harbour seals are common on the rocky islands. The Boston skyline recedes as the boat accelerates into Massachusetts Bay.
Crossing to Stellwagen Bank
The 90-minute crossing to Stellwagen Bank passes over Massachusetts Bay. The high-speed catamaran keeps the crossing reasonably short, but the open Gulf of Maine can produce 3–5 foot swells on this stretch. Once over the Bank, the water colour changes noticeably to a deeper green as the shallow plateau comes into range.
Humpback whale encounters
Humpbacks are the stars of Stellwagen Bank. The resident population has been studied for over 50 years — the on-board naturalist identifies individual whales by fluke pattern in real time, often telling you the whale's name, age, and calf history. Humpbacks on Stellwagen Bank are bold and curious — approaches within legal distance (100 yards) are routine.
Fin and minke whale sightings
Fin whales are the second-largest animals on Earth — at 75 feet and 80 tons, they dwarf the boat even at distance. They surface in a distinctive pattern (three blows on a 3-minute cycle) and dive without showing their flukes. Minke whales are smaller, faster, and more elusive but appear on most trips.

How to Choose an Ethical Tour
What ethical operators do
- Maintain 100-yard minimum from all whales (NOAA regulations)
- North Atlantic right whale sightings must be reported immediately to the US Coast Guard on VHF Ch. 16 — federal law requires 500-yard avoidance
- Book operators partnered with the New England Aquarium or other certified research programs
- Support Stellwagen Bank National Marine Sanctuary conservation programs
Red flags to avoid
- Approaching North Atlantic right whales at any distance — federal law, not just guidance
- Operators without a NOAA whale watch permit
- Feeding any wildlife encountered on the trip
