The Noulla Express was a Danish freighter built in 1939. After being seized by the federal government in a drug case, the vessel was purchased by a joint committee from the Palm Beach and Broward County reef programs and eventually sank in 1998. A small submarine that was used by drug smugglers was added to the wreckage and lies underneath the flattened cargo area. There are several tropical fish, filefish, and barracuda on this wreck. The Noulla is a part of the wreck triangle including the United Caribbean and the Sea Emperor.
