Why dive here
With 95+ marine species recorded in the area - including seals & sea lions, sea turtles and jellyfish lake - ALLIANCE offers some of North Sea Coast's richest wreck diving. Water ranges 3-19°C, warmest July, August, September.
The ALLIANCE, just off the North Sea Coast, is a genuinely engaging dive for anyone who enjoys a bit of history with their immersion. It’s a shallow wreck, sitting at just 10 metres, making it accessible for a longer bottom time, which we always appreciate. We find the character of this wreck really comes alive when you consider its history as a dangerous obstacle to navigation. Now, it’s a skeleton, broken but still substantial, and what was once a threat is now a vibrant home. You’ll spend your time here exploring the ribs of the hull, the twisted metal, and the scattered debris. We love how the light filters through the North Sea water, giving the entire scene a slightly muted, atmospheric feel. What truly brings the ALLIANCE to life, though, is the sheer amount of local marine life that has colonised it. You’ll find schools of cod sheltering in the crevices, flatfish camouflaged on the seabed nearby, and plenty of crabs scuttling over the rusting plates. It’s a site that really rewards a slow, deliberate exploration, perfect for photographers or anyone who likes to soak in the atmosphere of a historical wreck. Our favourite time to visit is on a calm day; the visibility can be excellent then, really opening up the wreck.

The history of the wreck known as the "Alliance" is shrouded in mystery. Lying in just 10 meters of water off the North Sea coast of Denmark, her origins, type, and the story of her sinking have been lost to time. This lack of information only adds to the allure of this shallow dive site. For divers, the Alliance offers an accessible yet intriguing exploration. Its designation as a "Dangerous Wreck" suggests the presence of sharp metal, collapsed sections, or entanglement hazards like old fishing nets, demanding careful buoyancy and awareness. Its shallow depth makes it an excellent site for novice wreck divers looking to gain experience, or a perfect second dive of the day, allowing for ample bottom time to search for clues about its forgotten past.
