The first impression of the WIT Concrete is “Wow, this wreck is huge!” It’s 350 feet long, 55 feet wide, and more than 50 feet tall from the sea floor to the top of the pilothouse. No matter where you are on the wreck, you cannot see both ends of the ship at the same time. The wreck is intact, and sits upright in about 95 feet of water.

The ship was a bulk carrier that was used for carrying fuel in the Pacific during World War II. It is made of concrete because it was used for carrying diesel fuel and gasoline, which would have reacted with a steel hull ship. For divers the concrete construction is a bonus because the wreck is almost completely intact.

The WIT Concrete was built in 1943 by the National Ship Company in Oakland, California, and originally sunk by Hurricane Marylyn in 1995 near Crown Bay. The wreck was blocking the boat channel, so it was raised from the bottom by the Army Corps of Engineers, and sunk at its present location off of St. Thomas.

The WIT Concrete segment in “Diving St. Thomas, Volume 1” features interiors of the stern areas and top storage room, the center pumphouse, and the bowhouse, as well as Scrawled Filefish, French Angelfish, Caribbean Reef Shark, Spotted Eagle Ray with Remoras, Hawksbill Turtles, and a cute little Trunkfish feeding among the Gorgonians.
