GLENARM HEAD (POSSIBLY) - Cornwall & Devon

The *Glenarm Head*, or what we believe to be her, is a proper wreck dive, sitting deep off Brighton. You’re looking at 46 metres, so this is one for the technical crowd, or at least those comfortable with extended bottom times. She was torpedoed in 1918, a casualty of the U-boat war, and that history really seeps into the dive. What we love about this wreck is her sheer scale. At over 100 metres long, you could spend a dozen dives here and still find new nooks. We usually drop onto the bow, which is impressively intact, and then work our way aft. Keep an eye on the ambient light-it fades quickly down here, but the silhouettes of the structure against the green water are something else. The wreck itself is heavily encrusted, with plumose anemones waving like miniature feather dusters in the slight current. Conger eels are always lurking in the deeper holds, and we've had some memorable encounters with large ling slipping through the broken deck plating. It's a sombre, beautiful dive, a real piece of maritime history that demands respect and proper planning.
