HMS Sahib (Submarine Wreck)
Site Overview
The HMS Sahib is a British submarine that sank off Gaeta during the Second World War and now rests at about 45 m, a haunting and historic technical dive. Its intact conning tower and hull are colonised by groupers, conger eels and gorgonians, and the deep, clear water adds to the atmosphere. It is a serious advanced and technical dive demanding proper planning, decompression awareness and respect for the fragile wreck. For those qualified, it is one of the most evocative WWII sites in the Tyrrhenian Sea. The site rewards careful planning, good buoyancy and a respect for Italy’s marine-protection rules, and remains a favourite among Mediterranean divers.
