What you'll do:

Enjoy a wonderful sail and swim aboard the wonderful day trimaran Cosmos. Cosmos has a US Coast Guard Certificaiton for over 20 guests, but is generally limited to smaller groups of up to 15. Her three hulls and wide decks make Cosmos as stable as she is comfortable. Her crew of 2 (a captain and mate) make sure your sailing goes off without a hitch.

For swim time, Cosmos features a lovely swim pad, a paddle board and swim floats. She has a bathroom with room to change aboard.

For larger groups or groups with catering and service needs, we recommend our Schooner Luna, which is also listed here.

Why we love it for your party:

• Cosmos's wide decks and light weight make for a lovely sailing experience.
