The Alkimos was a merchant ship, one of many that wrecked off the coast of Western Australia in 1963. What sets it apart are the persistent stories that it's a cursed ship.
Built in a Baltimore shipyard, misfortune seemed to have visited early on when it was said a welder was unintentionally riveted up inside the hull, and found a day later, after he had suffocated. There is another version, where it was several workers who were sealed inside its walls. Supposedly this occurred due to the tight deadline and hurried construction of the ship, which was one of over 2,500 being produced for the war effort.
