The SS Monte Carlo was originally built as an experimental concrete oil tanker ship during World War 1, but she was not finished before the war ended and was sold to private companies. Eventually she would fall into the hands of a syndicate of gamblers and turned into an off shore casino during prohibition, flaunting the laws of the US government from three miles off shore. This was until New Years Day when a storm blew in.
Ship Name: SS Monte Carlo
Built: 1921
Ship Type: Oil tanker
Made of: Reinforced Concrete
Wrecked: 1937

(Please note that the picture used in the title card is not of the SS Monte Carlo but is instead of the SS Atlantus which was part of the same fleet of concrete ships. She wrecked in the 1920s after serving as a ferry, but it was a better picture for capturing how the concrete ships looked than anything I could find of the SS Monte Carlo.)
