GREAVESASH - Cornwall & Devon

The Greavesash is a proper dive, a deep shot that rewards the effort. Lying in 46 metres, this isn't one for the casually certified, but for those with the training, she’s a beauty. We love dropping onto the bow, often silhouetted against the ambient light filtering down, with the stern rising slightly as you work your way along the deck. The hull is still largely intact, a testament to her robust build, and we've spent many an hour exploring the holds, peering into what would have been the engine room, feeling that tangible connection to maritime history. The marine life here can be surprisingly good, given the depth. Conger eels are often tucked into any available crevice, their eyes following you as you pass. Look for colourful jewel anemones coating the plates, and we’ve seen some hefty lobsters marching across the sand nearby. Our pick for timing is often a slack tide around midday for the best light penetration and calmer conditions; it makes the descent and ascent much more enjoyable when you’re not battling the current. It’s a serious dive, but the sense of accomplishment, and the sheer scale of the wreck, makes it a standout for us.
