OP Ślązak (Malutka) submarine (Jastarnia)
Ślązak is a former Soviet M-class (Malutka) submarine, operated by the Polish Navy from 1954 and struck from the fleet in 1965 to be sunk as a target ship. It is almost 50 m long and lies at about 31 m. The official list gives 25.2 to 31 m. A diver died here in November 2024, so it needs deep-diver training and strict buddy discipline.
Tiefe: 25–31 m
