GRANE - Cornwall & Devon

The Grane wreck, resting at 43 metres, is a solid dive for those who appreciate a bit of history. She was a steamship, torpedoed in 1918, and you can still make out the twin boilers and parts of her triple-expansion engine. It’s a proper penetration dive if you know what you’re doing, but even staying on deck offers plenty to see. Over a century underwater means she’s well-encrusted, attracting the usual suspects: conger eels tucked into dark corners, decent-sized wrasse, and plenty of plumose anemones waving in the current. Best tackled on slack water, it’s a good deep dive for experienced wreck enthusiasts.
