Often referred to as SS Thistlegorm’s sister ship, the Rosalie Moller is a very popular wreck of the northern Red Sea despite being suitable only for advanced tech divers due to its depth and visibility conditions. It was built at the beginning of the 20th century - in 1910 precisely - in Glasgow, Scotland. In 1938, it was repurposed by the Royal Navy to serve in the British war effort as an armoured cargo ship transporting coal to the troops in Egypt. At the time, the Suez Canal was heavily guarded by the Third Reich: British cargo ships had to circumnavigate Africa and enter the Red Sea from the Gulf of Aden.
Similar to the Thistlegorm, she was spotted by German bombers while moored at the Safe Anchorage H - not far from what today became Ras Mohammed National Park - and sent to rest 50 metres below the water’s surface with two well-aimed bombs. She now stands in sailing position, beautifully preserved thanks to its depth and location that protected it from mass dives.
The Rosalie Moller is 108 metres long and almost 20 metres tall. She rests on a sandy bottom with the deeper parts in 50–55 metres of water and the main weather decks at 35 metres. The mast reaches a depth of 18 metres and due to its depth, divers can either spend no more than a couple minutes at the maximum depth or dive using twin-tanks and decompression gases, which is the recommended option.
At approximately 55 metres, divers can admire the huge rudder and propeller. Handrails, ladders, and walkways can be observed while swimming along the main deck. It is also possible to explore the wreck’s holds and bridge. However, unlike the Thistlegorm, this ship was mainly transporting coal and she has been stripped of most of the equipment.
Diving on the Rosalie Moller can prove to be quite challenging. Due to its depth, diving here requires technical training and equipment or else the available time before the non-decompression limit would be too short for any significant exploration. Furthermore, the visibility can be as low as 10 metres - something atypical for the Red Sea, but very common on the Rosalie Moller. Dive here only if you feel confident about diving at significant depths with low visibility.
Nevertheless, if you have the necessary training and experience, diving on the Rosalie Moller can be extremely exciting. The ship spent almost a century underwater, becoming an integral part of the underwater ecosystem. Today, it provides shelter for many benthic and pelagic species, including large specimens of groupers and lionfish, as well as the occasional gray reef shark hunting in the area. It is also extensively colonized by several species of anemones and deep-water corals, and it has tremendous historical and naturalistic value.
