The UnderSea first entered service in 1968 as the personal submarine tender to Dr. Perry of Perry Oceanographic. Over the years, sturdy and dependable vessel became one of the most renowned dive boats in the world, famously known as the Undersea Hunter during its expeditions to Cocos Island and appearances in IMAX adventures across the South Pacific. The ship later underwent an extensive shipyard refit, which included stretching the hull to 105 feet, adding a new superstructure and extended sun deck, and equipping it with a bulbous bow and advanced stability system, ensuring both comfort and performance for modern expeditions.
