DEMETRIOS - Cornwall & Devon

Okay, the Demetrios. You’re not going deep here, which is half the fun. This motor vessel, grounded back in '92 after her tow parted, is a fantastic shore dive. We love that you can genuinely explore this wreck, even at just 3m. Imagine swimming over those massive hull plates, almost 160m of ship broken into two major sections. The ship's ribs are exposed in places, creating these perfect little alleys for wrasse and pollack to dart through. Our favourite is finning through the larger breaks in the superstructure, feeling the gentle surge push you through what used to be a cargo hold, now home to forests of kelp and anemones. You’ll spot velvet swimming crabs clinging to the rusted metal, and in summer, shoals of juvenile fish just hang in the calmer patches. It’s an incredible site for photographers or anyone who just wants to spend a good hour poking around a proper wreck without the need for advanced certs. Just pick a calm day, and time your dive for slack water around high tide for the best visibility.
