The Seaworld Explorer is a state-of-the-art semi-submarine developed for use on the Great Barrier Reef. The vessel does not submerge; you descend into the hull of this underwater observatory and sit in air-conditioned comfort five feet below the surface of the water, exploring amazing sea life through large, clear glass windows.
After your air-conditioned bus ride to the pier, you board a ferry that takes you to the Seaworld Explorer, waiting near Arashi Reef. The captain and knowledgeable narrator guide the semi-submarine through this wondrous reef filled with beautiful coral formations and spectacular tropical fish.
Leaving Arashi Reef, the Seaworld Explorer takes you to the wreck Antilla, a 440-foot German freighter destroyed during World War II. The huge ship lies on her side in 60 feet of water, measuring 440 feet in length, this is the largest wreck in the Caribbean.
