The Rozi is a steel tug boat built in 1958 and scuttled off Valletta, Malta, in 1992 as a tourist submarine attraction. It is 35 metres long and lies as a reef and wreck site in the Mediterranean Sea, between 20 and 34 metres, reached from shore. It is rated an advanced dive and includes overhead environments. It is considered one of the most popular dive sites in the Maltese islands. Big reef fish, cephalopods, frogfish and scorpionfish, moray eels and schooling fish are resident. Crustaceans and nudibranchs are occasionally seen.
