Why dive here
With 50+ marine species recorded in the area - including dwarf minke whales and jellyfish lake - HARM offers some of Baltic Coast's richest wreck diving. Water ranges 1-17°C, warmest July, August, September.
The HARM, a motor vessel built in 1955, lies at a manageable 22 metres in Lindalssundet, just outside Stockholm. She sank after a collision with the MV Stavklint, and now rests upright, making for a straightforward exploration. We usually find decent visibility here, letting you appreciate the intact structure – the bridge section is particularly interesting, often hosting curious blennies and even small cod. Penetration is possible for experienced wreck divers, but even staying on the exterior offers plenty to see. It’s a solid Baltic wreck dive, good for those looking for a relatively accessible piece of history.
