Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - GEORGIOS MARKETTOS (PROBABLY) offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Georgios Markettos, or at least what we strongly suspect is her, sits deep off the Cornish coast. Dropping down to 53 metres, this is one for the technical divers, no question. We love the challenge of this dive, descending into that cool, green water, knowing you're heading for something seriously old. The wreck herself, an 88-metre steamship, is largely broken but still holds enough structure to feel like a proper wreck dive. You’ll find the two massive boilers standing proud, often shrouded in schooling bib and pollack, a real visual treat when the light catches them. Inside the engine room, if you can navigate the silt, there's a triple-expansion engine waiting to be explored. We'd suggest checking the tides meticulously here; even a slight current at the surface can mean a serious drift at depth. This site suits experienced divers who appreciate history and don't mind a bit of a depth challenge for the reward of a classic British wreck. It's a deep dive that feels like a journey back in time, the metal framework now completely part of the seabed.
