Revolutionary in design, this new catamaran is the only research vessel in North America with hybrid-electric propulsion. She runs virtually silently on electric power for our 2½-hour study cruises on Long Island Sound.
The 64-foot all-aluminum vessel replaces a diesel-powered trawler. Public cruises, school group charters and private parties now enjoy a cleaner and greener venue on Long Island Sound .
Study marine biodiversity from the water’s surface down to the bottom for a first-hand understanding of Long Island Sound's interdependent marine life. Participants utilize such sampling techniques as a plankton tow, bio-dredge, mud grab and otter trawl that may bring up fish, crabs, squid, skates and more. A video-microscope and touch tank on board enhance observations.
Passengers must be over 42" tall. If under the age of 18, you must accompanied by an adult. Capacity: 35.
ADVANCE RESERVATIONS STRONGLY RECOMMENDED. Capacity is limited. Cruises do sell out. We recommend you purchase your tickets in advance. (Walk-up tickets are sold, space permitting. Ask any cashier when you arrive.) The U.S. Coast Guard sets limits for number of passengers on board.
Cost: $29.95 per person
Aquarium Members: $24.95
Discounted Triple Combination = Cruise + Aquarium admission + IMAX® movie: $49.95 adults; $47.95 youths (13-17) & seniors (65+); $42.95 ages 12 & under.

Our new, quieter, greener boat offers a unique platform for corporate team building, meetings, parties and more. We can custom design a private cruise for companies and individuals. A range of food and beverage options are available. Add an exciting program: marine life study, remotely operated underwater vehicle, marine navigation, lighthouse tour, history tour, bird watching and more. Capacity: 40 people.
If you have more people or less time, consider a special event on our spacious dock and boat without the cruise. We can accommodate up to 65 people with broader catering choices. You can still add an interpretive program: remotely operated underwater vehicle, marine navigation, bird watching, animals of Long Island Sound and more.

Cruises can occur in rain, cold and wind, and are canceled only if conditions are dangerous. Please dress accordingly!
All observations made on study cruises are recorded. This data is part of an ongoing student-based research project called the Long Island Sound Biodiversity Study. Details ...
Norwalk's public dock is just across the river from our dock. Join us to learn what's under your keel, or spot seals or experience the first hybrid-electric research vessel in the U.S.A. There is plenty here for a weekend trip. Check out this travel story by New England Boating, Report from the field: Norwalk, CT.
Designed by Incat Crowther of Australia, Spirit of the Sound was built in Mamaroneck, NY, at the Robert E. Derecktor Inc. shipyard, with construction managed and integrated by Alternative Marine Technologies (Amtech). Her hybrid-electric propulsion system was made by BAE Systems Inc., Corvus Energy and Northern Lights Hybrid Marine.
Major contributors include: the Per and Astrid Heidenreich Family Foundation, George & Carol Bauer of Wilton, and The TK Foundation.
Our new boat's godmother, Astrid Heidenreich, breaks the ceremonial bottle of champagne on the bow of our new boat. Pulling the boat closer to the dock is Project Manager Robert Kunkel, Amtech.
