The UnderSea first entered service in 1968 as the personal submarine tender to Dr. Perry of Perry Oceanographic. This sturdy and brave ship became one of the most famous dive boats in the world as the Undersea Hunter voyaging out to Cocos Island and in IMAX adventures around the South Pacific. The ship was graced with a massive shipyard refit including: stretching the hull out to 105 feet, a new superstructure and extended sun deck, a bulbous bow and stability system.
