The SS PRESIDENT COOLIDGE was a passenger ship built for the Dollar Steamship Company (later American President Lines) by Newport News Shipbuilding. Entering service in 1931, the ship was homeported in San Francisco and used on the Trans-Pacific route to China, the Philippines and Japan via Honolulu. At 22'000 GRT and 200m in length with a turbo-electric propulsion system and with luxurious art deco fittings, she represented the best of American passenger ship design of the time.

 Requisitioned as a troopship in 1941 following the outbreak of WW2, the ship was lost in Espiritu Santo (Vanuatu) on 26 October 1942 when she struck a friendly minefield at the entrance to the Segond Channel. Today, the ship is one of the largest ships accessible to recreational divers. Diving the wreck is a spectacular, awe inspiring experience. This presentation will provide an overview of the fascinating story of the ship, how and why she was lost, her condition today and some direct observations on what it is like to dive the wreck.
