Site details

The Rosalie Moller is a 108 m British WWII collier and a sister ship of the famous SS Thistlegorm, sunk by German aircraft in October 1941 off Gubal Island near Hurghada. She sits upright on a sandy bottom with the main deck around 35 m, masts rising to about 17-18 m and the propeller and rudder visible on the deeper stern. Hard and soft corals now cloak the hull, and the holds and bridge can be penetrated although most artefacts have been removed.
