SS Marine Sulphur Queen and an image of her remains recovered by the US coast guard SS Marine Sulphur Queen, T2 tanker ship converted to carrying molten sulphur, noted for its disappearance in 1963 near the southern coast of Florida, taking the lives of 39 crewmen.
In the investigation, the Coast Guard determined that the ship was unsafe and not seaworthy, and never should have sailed. The final report suggested four causes of the disaster, all due to poor design and maintenance of the ship. 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, an inaccurate and incomplete version of the ship's disappearance is often used to justify Bermuda Triangle conspiracies.
