Why dive here
With 95+ marine species recorded in the area - including seals & sea lions, sea turtles and jellyfish lake - HENA offers some of North Sea Coast's richest wreck diving. Water ranges 3-19°C, warmest July, August, September.
HENA, a small cutter sunk off the North Sea Coast in 1984, sits upright in just 8 metres of water. It's an easy dive, often with decent visibility for Denmark, making it ideal for those new to wreck diving or looking for a relaxed bimble. We usually find crabs scuttling over the deck and small schools of fish darting in and out of the wheelhouse. The wreck itself isn't huge, but it's largely intact, offering a good sense of its original form. It’s a solid option for an afternoon out, especially if you’re keen to tick off a Danish wreck without the deeper technical demands.
