MARATHON, KEY COLONY BEACH FLORIDA KEYS DIVE
This is a 188 foot ship sunk in 1986 and it rests sitting upright and in 120 feet of water. She is 85 feet long and it is possible to enter the hull.
The Thunderbolt was intentionally sunk on March 6, 1986, as part of the Florida Keys Artificial Reef Association project. She now lies intact and upright on a sand bottom in 120 feet of water four miles south of Marathon and Key Colony Beach.
According to the National Marine Sanctuary site:
The Thunderbolt’s hull is 189 feet long with a forecastle, which served as the cable handling area, and has a cruiser stern. Prior to being sunk, the ship was stripped of all but a few major pieces of equipment. The most-prominent remaining features are a horizontal cable handling reel which lies at 80 feet and is centered on the after-end of the forecastle deck and the remains of the ship’s superstructure, including the observation deck located at 75 feet.
The aft-end of the superstructure has been cut away, exposing the interior of the hull at the engineering space. The rudder and propellers, which lie at 120 feet, also remain to complement the stern section of the hull.
