In order for passengers to reach the submarine they board a shuttle ferry, then they enter the submarine via steep stairs. When the submarine goes down they see corals, sunken ships, treasures, and fish through large viewports. When the submarine ride is finished the passengers are returned by the ferry to shore where they are given dive certificates. Some 12 million passengers have taken the Atlantis submarine tour to date.
The Atlantis XIV, which sails from Waikiki Beach, Hawaii, accommodates 64 passengers and is the world's largest passenger submarine.
Atlantis was founded by current president and CEO Dennis Hurd, a former designer of submersibles for North Sea oil rigs, with US$3 million borrowed from friends and relatives.[1] The company launched the world's first commercial passenger submarine tours in Grand Cayman in 1986. It has since serviced about 12 million passengers.
There are three main areas of operations:[2]
Atlantis Guam Inc. operates the Atlantis V, a 65-foot air-conditioned submarine that can carry up to 48 passengers.[3] The tour begins from Apra Harbor and explores the marine life in the GabGab reef.[4] The reef has corals that were formed over 1,800 years ago.[5] Varieties of fish that can be seen are moorish idol, unicorn fish, spade fish, sea turtle, giant trevally, clownfish, surgeon fish, and occasionally sharks. Other highlights of the tour are diving to depths of 45 meters and curtain of air bubbles as the submarine ascends to the surface.
