Deep Baltic wreck dive for experienced divers.
Deep Baltic wreck dive for experienced divers.
A local wreck operator is the practical way to manage depth, access, and conditions.
S/S Nicomedia is a Baltic wreck dive off Sweden, part of the German cargo ships sunk by E19 in 1915. It is a deep boat dive for experienced divers, with the wreck sitting in the mid-20s to upper-30s meters and the structure now starting to break apart. The dive is about history, hull shape, and careful planning rather than bright water or easy access. Treat it as a serious wreck outing that rewards disciplined buoyancy and gas management.

Safety Notes
Do not penetrate deteriorating sections without the right wreck training; watch for loose steel and snag points.
Access Restrictions
Best handled through a local wreck operator because the site is deep and the Baltic conditions are not forgiving.
Legal Notes
