Cosmos is our Classic Mahogany Performance Trimaran. She blends style with fantastic sailing performance for the perfect blend of safety, stability, and luxury. Boasting a Coast Guard capacity of 26, Cosmos is most comfortable for up to 15.
Refit and re-imagined in 2023 for the SailHamptons fleet, Cosmos is our boat for casual sails and wonderful Hamptons Sailing. For larger groups or events requiring catering and service, we always recommend Schooner Luna as an alternative.
Cosmos offers morning, afternoon and sunset sails. She is perfect for a lunch trip to your favorite Shelter Island Restaurant. Cosmos is the centerpiece to our weekday morning Yoga and Wellness program in partnership with Evolveast Yoga.

She is perfect for that casual sail with our without a swim stop, and a picnic aboard. Cosmos is equipped for smaller groups. Crewed by 2, a Captain and Deck/Steward, we ensure every charter is the best possible experience.
Cosmos has lovely galley-ware, serving-ware, cups, plates, ice and everything needed for any occasion. Guests are welcome to bring what they want for food and drink.

Cosmos has an easy to use swim ladder and is perfect for a swim stop. There are swim floats, a swim-pad, and a paddle-board to be used and enjoyed. With her shallow draft, Cosmos fits at some of the most beautiful secluded spots around Shelter Island Sound.
