The MV Odile (also known as the Margit) was an old steam-freighter that sank in course of a bombing attack on April 4, 1942 at Karkara reef, off Grand Harbour (La Valletta). The wreck was discovered in late Seventies.  The hull is in poor condition because it was devastated by the explosions, (the bow and the propellers are missing), and lies on its port side. The wreck covers a large area and is difficult to find in poor visibility without local knowledge.  It is recommended that only experienced divers actually penetrate the wreck as proper equipment including reels are needed.

Maximum depth - 24 metres
