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) - POTLESS offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
Potless, a fishing vessel sunk in 1976 after a collision with the ferry 'Southsea', isn't deep. In fact, it's barely a metre, making it an ideal spot for a leisurely snorkel or even a very shallow dive if you fancy getting properly horizontal. What we love about it, though, is its accessibility and the sheer amount of life that has moved in. You'll find the wreck spread across the seabed, a jumble of metal now completely encrusted. We've seen shore crabs scuttling amongst the plates, their claws waving as you pass. Small wrasse dart in and out of the crevices, and sometimes you'll spot a flatfish, almost perfectly camouflaged, pressed against the sand nearby. It’s a gentle introduction to wreck exploration, perfect for building confidence or simply enjoying a different perspective on the underwater world. Our top tip? Go at high tide for the best visibility and a little more water to play in; it can get quite silty if there’s been a lot of boat traffic.
