Why dive here
With 118+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and orcas - MARY COLES (POSSIBLY) offers some of Northumberland & Northeast's richest wreck diving.
The Mary Coles, possibly, is one of those North Sea wrecks that just delivers. We’ve plunged down to her at 34 metres more times than we can count, and she rarely disappoints. She’s a sailing vessel, sunk way back in 1882, a victim of a rough passage and a misplaced rock. What you’re diving now isn't some intact ghost ship. Instead, it’s a beautifully scattered debris field, with ribs and planks spread across the seabed, almost like an archaeological dig. This isn’t a rummage-through-the-holds kind of dive. It's more about tracing the outline of what was once a proud ship, now entirely given over to the sea. Shoals of coalfish dart through the skeletal remains, and we’ve often spotted massive ling curled up in the deeper recesses, almost camouflaged against the dark metal. We love the way the light filters down, even on a cloudy day, creating an eerie glow around the scattered timbers. For divers who appreciate history and the slow reclamation by nature, this is a truly special dive. It’s perfect for experienced cold water wreck enthusiasts comfortable with deeper profiles and the often-moody conditions of the North Sea. Just be prepared for strong currents; they’re a regular feature out here.
