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) - TANNATUS offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Tannatus, a steamship that ran aground on Praa Sands back in 1921, now sits as a scattered wreck, a stark reminder of Mount's Bay's unforgiving nature. What's left of her is spread across the seabed, broken but still intriguing. We've found the stern section offers the most interest, often home to decent-sized conger eels tucked into the crevices. Look out for the resident crabs scuttling over the plates, and in the summer months, a surprising number of wrasse darting through the remains. It's a shallow dive, generally less than 10 meters, making it a good option for less experienced divers looking to explore a piece of history without deep water challenges. Be mindful of surge on choppier days, though, as she’s quite exposed.
