Dive-site story
Resting in the outer Stockholm archipelago, the steam tugboat Tyr offers a classic cold-water Baltic wreck dive. The vessel sits upright on a silty seabed with its hull, deck equipment, and towing gear largely intact due to the low salinity and absence of shipworms. Low ambient light and cold depths require disciplined buoyancy control to prevent stirring up the fine bottom sediment.
Well-preserved wooden deck details and towing gear protected by brackish Baltic waters
Upright wreck silhouette emerging dramatically out of the green ambient gloom
Atmospheric penetration opportunities for trained overhead divers around the wheelhouse and machinery spaces
Location

Seasonality
Late autumn generally offers the clearest visibility after the summer plankton bloom subsides.
