SS Marine Sulphur Queen

The SS Marine Sulphur Queen went down off the coast of Florida in 1963 . It was found to be unsafe and not seaworthy, and never should have sailed . The loss of the ship was the subject of lengthy litigation between the owner and families of the missing men . Despite the clear cause of the disaster and its last known position being off Florida in the Gulf of Mexico, an inaccurate and incomplete version of the ship's disappearance is often used to justify Bermuda Triangle conspiracies . The Coast Guard investigation concluded several facts about the Marine Sulphur Queen which, by themselves, should have prevented the ship from going to sea at all . The most important were the incidents of fire beneath and along the sides of the four large sulphur tanks .
