The Cassimir is a 390 foot long tanker that is in 120 feet of water with the highest part rising to about 85 feet. It is also known as the "WR-2 Wreck". The bow is pointing up toward the sky and the anchors are still in place. There is a small sandy area that separates the bow from the other sections of the wreck. The next objects that are visible are some I-beams that stick up out of the sand, which have long ago lost their plates. The next section is a flat deck that once contained the pilothouse that has fallen off into the sand. There are a couple of other decks that are separated by holds. Most of the stern section intact and is angled into the sand with the actual stern pointing upward and it is listing to port. Some of the hull plates are missing which allows the divers to look into the ship.
During the summer, the water temperature ranges from the upper 70's to the low 80's. Visibility averages 70 feet but can get up over a 100 feet. Large schools of amberjack and spadefish can be seen swimming around the wreck. Sea bass and tropical fish, such as the Queen Angel can also be seen regularly.
The Cassimir transported molasses from Baltimore to Cuba to be used in the rum making process. In February of 1942, Captain J.A. Bodman and his crew of 36 left Santiago, Cuba for the return voyage. On the morning of February 26, 1942, the Cassimir was moving through a dense fog about 50 miles east of the tip of Frying Pan Shoals. Also moving through the fog was the freighter, Lara. The ships were unable to change course and the bow of the Lara cut a gash into the starboard side of the Cassimir at amidships. The Cassimir started to list to starboard and Captain Bodman gave the order to abandon ship. All but five of the crew was rescued by the Lara, which didn't have any damage from the collision. The survivors were taken to Charleston, SC.
The Cassimir floated toward the north for a few hours before she finally slipped beneath the surface of the water.
