Located near Cirkewwa, this site explores the Tug Boat Rozi. The experience is great for all levels of scuba divers. MV Rozi was a Bristol built tugboat launched in 1958 as the Rossmore by Charles Hill & Sons Ltd. In 1969 she was sold to Rea Towing Company and renamed Rossgarth. In 1981 she was sold to Tug Malta, and renamed Rozi, operated in Grand Harbour Valletta.
Rozi was scuttled in 1992 off Ċirkewwa as an artificial reef and attraction for Captain Morgan's Underwater Safari Tours. The submarine no longer operates, but the wreck is a popular diving attraction sitting upright, intact except for its engines and propeller, on a sandy bed at a depth of 35 metres (115 ft).
