The dive

The Cox is a scattered site rather than a standing hull. The dive works through wreckage spread between 12 and 30 m (40 and 100 ft), where twisted steel plating, exposed machinery and the ship's propeller are the main features. She sank near the wrecks of the Cumberland and the Henry Chisholm.

Built in 1901 as the passenger steamer Puritan, the ship was bought in the 1930s by George Cox, an entrepreneur from New Orleans, refitted and renamed George M. Cox in 1933. On her first cruise, with special guests aboard, she struck the shoals near the Rock of Ages Light in fog on 27 May 1933. The 127 passengers and crew were rescued and spent the night in the crowded lighthouse and on the surrounding rocks, and the ship stayed on the rocks until an October storm broke her up.
