Diving the U-11 Submarine

Site Overview

U-11 Submarine is a wreck dive site in Baltic Sea – Schleswig-Holstein (Ostsee), Germany, reached from the base town of Fehmarn. The U-11 is a WWII submarine wreck lying in shallow, accessible water off Fehmarn, its conning tower and hull clearly recognisable. It is one of the most popular wreck dives in the region for Open Water divers, with cod and pollack weaving through the structure. The site reaches a maximum depth of 15 m with an average profile around 12 m and a shallow start near 10 m, which places it firmly in the intermediate category and means divers should hold at least an Open Water certification. Conditions are typical of the Baltic Sea environment: visibility generally runs from 5 to 15 metres, the current is moderate, and the water temperature ranges between 6 and 19 degrees Celsius with low surge exposure. The marine community is centred on Atlantic Cod, Pollock, Conger Eel, Common Cuttlefish, Nudibranchs (Flabellina spp.), Small-spotted Catshark, and the full species list is detailed below for divers planning a trip. The combination of wreck topography and sand and steel substrate gives U-11 Submarine its distinctive character within the Baltic Sea – Schleswig-Holstein (Ostsee) region. U-11 Submarine is a strong representative of why German diving is so highly regarded, blending the geology, history and biodiversity that define the country's underwater exploration. It pairs naturally with the other sites of the Baltic Sea – Schleswig-Holstein (Ostsee) region for a varied holiday, and with the right thermal protection and, where relevant, the correct specialist training, it offers a memorable dive for photographers, naturalists and wreck, reef or freshwater enthusiasts alike. As with every German dive, a drysuit and a careful respect for cold-water limits turn a good day into a great one.
