Wreck S103 - North Sea Coast

The S103 is one of those wrecks that really gets under your skin. Lying in the North Sea, it’s not for the faint of heart, but if you’re comfortable with cooler water and potentially low visibility, it delivers a proper wreck dive. We’ve found it’s best when the tides are slack, offering a bit more time to explore the superstructure. What we love about the S103 is its intact nature; she's still very much a ship, not just a pile of scattered debris. You can poke around her holds, peer into the bridge area, and really get a sense of her past life. The metalwork is completely encrusted with an amazing tapestry of plumose anemones and dead man’s fingers, swaying gently in the current. Ling and cod are often lurking in the darker corners, and we’ve spotted plenty of inquisitive crabs scuttling across the deck. It’s a dive for those who appreciate history and the way the sea reclaims its own, turning steel into a vibrant, living reef.
