Aptly named the “Titanic of the Caribbean,” the luxury liner Bianca C is the largest wreck (600 ft/180m) to be explored in warm waters.
In October 1961, during the early morning hours, an explosion occurred in the engine room while the ship was at port. As the ship started burning, passengers and crew were evacuated. After burning for two days, the ship was towed away from the mouth of the harbor as it slowly began to sink.
To this day, the Bianca C’s anchors are still lying in the mouth of St George’s Harbor. She currently lies beneath about 165 feet (50m) of water. Today, the Bianca C is the Caribbean’s largest divable wreck.
