The Mon Tiki catamarans—built by the people who sail them. Inspired by traditional Polynesian designs, our eco-conscious catamarans are the only US Coast Guard certified sailing vessels in Montauk and the largest on Long Island. Book a private charter and create your own special seafaring adventure. Enjoy a relaxing day sail, swim with our included SUP paddle boards, or take in a sunset cruise on the bay. Whether you’re a group of 1-100 passengers, we’ve got a catamaran adventure that’s right for you!
