Memorable and Fun for Everyone

Launched and very profitably operating is the first semi-submersible, 49-passenger viewing vessel completely built in high-strength, low maintenance fiberglass reinforced plastic. Boat number one, named SS NAUTILUS, was constructed at the Willard Marine facility in California for Catalina Adventure Tours, Inc., which serves thousands of annual visitors to Avalon, Catalina, enabling them to explore and view the beautiful coastal island waters and sea life. An investment has been made in the molds for this vessel so that sisterships can be constructed and receive U.S. Coast guard passenger approval in an expeditious and cost-effective manner. This vessel is the perfect destination activity for those in the tourism industry. In the right operating environment, this unique vessel will amortize its capital cost in two to three years. The revenue from the special Fish Feeder Concession option can pay for the cost of crew.  Contact us to develop a semi-submersible vessel for your business.
