Why dive here
With 95+ marine species recorded in the area - including seals & sea lions, sea turtles and jellyfish lake - HANNA offers some of North Sea Coast's richest wreck diving. Water ranges 3-19°C, warmest July, August, September.
The Hanna sits upright at 23 meters on the seabed, a steamship that’s seen better days. We’d classify it as a dangerous wreck, so this isn't a penetration dive for the inexperienced. What you will find, though, is a structure that’s become home to a lot of local North Sea life. Expect cod and pollock hovering around the superstructure, and if you look closely, crabs tucked into every crevice. Visibility can be a bit challenging, typical for the area, so pick a calm day and focus on the details. It’s a good wreck for those who appreciate history and don't mind a chillier dive.
