    The Clan Macvey. Now here’s a wreck that really gets our attention off the Lizard. She's a WWI casualty, torpedoed by a German U-boat in 1918, a brand new ship on her maiden voyage too. Tragic really, but it makes for a cracking dive. At 18 metres, she’s accessible to most, though we’d suggest some solid experience with UK currents; they can be frisky out here. What we love about the Macvey is how much of her remains. She’s broken, of course, but the sheer scale of the hull is impressive. You’ll fin over huge plates, past ribs that reach up like skeletal fingers, and into cargo holds now colonised by dead man’s fingers and anemones. Look for the engine room, often bustling with conger eels – some of them absolute monsters. Visibility can vary, as it always does in these waters, but on a good day, when the sun penetrates the surface, the whole wreck glows with a ghostly light. It’s a proper historical dive, a poignant reminder of the war, and a fantastic habitat for local marine life. Our pick for a classic Cornish wreck dive.
