Our Classic Mahogany Trimaran Blends Performance with Luxury and Stability for Casual Sails, Swims and Sunsets

Cosmos is our Coast Guard Inspected mahogany performance trimaran that perfectly blends safety, stability, performance and luxury. Suitable for all size groups, is comfortable for groups of up to 14, and is certified for up to 26 guests. She is available primarily in Sag Harbor with weekday availability in Shelter Island, the North Fork, and Points East.
Cosmos provides an lovely real sailing experience while staying flat and stable in the water. Fresh reimagined and refit in 2023 with new deck accommodations, Cosmos brings to our guests the same wonderful luxury finishes and comfort you’ve come to expect from the SailHamptons feet.

We consider Cosmos to be our Schooner Luna’s little sister. She is perfect for that casual sail with our without a swim stop, and a picnic aboard. Cosmos is stocked for a great casual experience for smaller groups and groups with less catering and service needs than offered by Luna. Crewed by 2, a Captain and Deck/Steward, we are able to provide wonderful hospitality to our guests aboard.
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, or we are happy to provide scrumptious Catering Options.

Cosmos has an easy to use swim ladder and great spots to jump off the side for a mid sail dip. There are swim floats, a float pad and a paddle board aboard for guests to use.
