Why dive here
With 50+ marine species recorded in the area - including dwarf minke whales and jellyfish lake - JM-PM offers some of Baltic Coast's richest wreck diving. Water ranges 1-17°C, warmest July, August, September.
The JM-PM wreck sits at 40 meters on the Baltic seabed, a fascinating, non-dangerous dive for those comfortable with deeper wrecks. We found the visibility here can be quite good, letting you appreciate the vessel's structure. It’s a quiet spot, often just us and the local fish, which have made the sunken metal their home. A solid choice for divers looking to explore a piece of history without the crowds.
