KOL-166 - Bornholm

KOL-166 isn’t just a wreck, it’s a time capsule from the Baltic Sea’s often harsh fishing past. This 24.5-meter trawler went down in 1978, taking five crewmen with her. That solemn history adds a weight to the dive, a tangible sense of a moment frozen. She sits upright at 60 meters, remarkably intact for a wreck of her age and circumstances. We love exploring the wheelhouse, still standing proud, and peering into the fish hold, now home to clouds of cod and schools of inquisitive wrasse. The cold, clear waters of Bornholm have preserved her well, painting her in a palette of deep greens and browns from the encrusting life. Visibility here can surprise you, often stretching to 15-20 meters, which makes the descent through the gloom feel more like a grand reveal than a mere drop. Our favourite detail? The trawl doors, still attached and splayed out as if she just finished a final fishing run. This is a dive for technical wreck enthusiasts who appreciate history and the unique, rugged beauty of a Baltic wreck. If you're looking for vibrant corals, this isn’t it. If you crave an evocative piece of maritime history, she delivers.
