About our Vessels

Dolphin Fleet Vessels: Each Dolphin Fleet vessel is specifically designed for whale watching and comfort. Designed by GulfCraft, each vessel is built of aluminum with a double chine for added stability, and is powered by 3 Detroit 1271TI diesel engines. There is a sundeck on the second level and a walk out platform for viewing on the bow. There are no open rails on the boat, so you’re in the boat, not on it, with ample seating on both upper and lower decks. The interior cabin has seating for over 100 passengers and the cabin is centrally heated and air-cooled. We limit the number of passengers we carry in an earnest attempt to make each trip satisfying and comfortable. Our vessels are clean and our restrooms are spotless.

Our galley: We serve a complete breakfast menu with eggs, bagels and a number of breakfast specials. The luncheon menu serves items such as pizza, hot dogs, hamburgers, chicken, chowder and chili just to name a few items. Beer, wine and cocktails are also available. Need film or a camera? We carry that too. The galley is not overpriced and compares favorably with local vendors. We are happy to plan meals for tour groups as well so please don't hesitate to ask.

What to bring: You”ll be out on the open ocean so you should bring sun block, sunglasses, and perhaps some warmer cloths. Wear sneakers or shoes with good traction. We suggest a camera and binoculars for that close up of whales, birds and Provincetown scenery.

Scientific Research

A naturalist accompanies every cruise to serving as an interpretive guide to the ecology and natural history of Cape Cod and Massachusetts Bays with emphasis on whales, other marine life and marine birds passengers are likely to see.

With the research collected on board the Dolphin Fleet well over 1,300 humpback whales have been identified since 1975, with this data we can provide our passengers with the personal histories on many of the humpbacks found in our area.

The opportunistic research collected on board each Dolphin Fleet cruise includes identification of different marine mammal species, including: humpback, finback, right and minke whales; individual whale behavior and identification, as well as associated environmental and oceanographic data.

This information is shared with other research institutions, as well as conservation groups and resource managers. By whale watching with the Dolphin Fleet, you will effectively be taking part in a scientific expedition as well as helping to support vital research on endangered whales.
