Schiffswrack Prahm (Wreck) is a compact Baltic prahm off Fehmarn that rewards a guided wreck dive with simple orientation and good structure. The wreck sits upright on the seabed and is small enough to read in one pass, so the dive feels more like a controlled survey than a long swim. Cold water and boat timing are the main planning variables, along with exposure protection and comfort around wreck structure. Flounder, crabs, sea stars, sea trout, and other Baltic fish gather around the wreck.
