MYSTERYTU - Cornwall & Devon

The MYSTERYTU isn’t your typical big, deep wreck, and that’s precisely why we love it. This isn't about penetration or grand history; it’s a delightful, accessible little sailing vessel, roughly 8.8 metres long, that ran aground between Teignmouth and Dawlish back in 1976. What makes it special is its character. It’s sitting right there, shallow enough that you can often spot parts of it poking out at low tide, making it a fantastic shore dive when the conditions are calm. We’d suggest planning your dive for slack water, preferably on a high tide, to maximise your time with it. The MYSTERYTU is a perfect site for newer divers or those who just want a relaxed potter, exploring at a leisurely pace. You’ll find the hull offers plenty of nooks and crannies for crabs and lobsters, and often small schools of pollack will hang around the remnants of the mast. While it might not have the drama of a deep-sea freighter, we’ve spent many happy hours here just observing the subtle life that has made this humble yacht its home, feeling the gentle push of the tide and enjoying the simplicity of it all.
