Why dive here
With 95+ marine species recorded in the area - including seals & sea lions, sea turtles and jellyfish lake - SIMA 3 offers some of North Sea Coast's richest wreck diving. Water ranges 3-19°C, warmest July, August, September.
The SIMA 3, a substantial lighter vessel at 82.3 metres long, rests upright on the seabed off Denmark’s North Sea coast. At a comfortable 20-metre depth, it’s a dive that offers a real sense of exploration without pushing deep limits. We found the wreck itself quite open, which makes for easy penetration into some of the larger holds, perfect for those wanting to explore inside. Expect to see plenty of cod and pollack hanging around the superstructure, with crabs and lobsters tucked into every crevice. It’s a rewarding dive for those who appreciate solid wreck exploration over coral colours.
