HMS ARFON - Cornwall & Devon

The Arfon is one of those wrecks that just delivers. Not just because of her story – a minesweeper sunk by a German mine in 1917, taking ten men with her – but because she’s still so intact. She rests upright on a sandy seabed at 33 metres, her bow pointing northeast. We love how her shape is still so defined, from the stern, where you can still make out the prop shaft and rudder, all the way to the bow section, which rises a good four or five metres off the seabed. Even on a day with average visibility, the Arfon feels substantial. Swimming along the deck, you’ll find plenty of nooks and crannies to peer into, home to conger eels and squat lobsters. Our favourite part is the engine room, which is fairly open and usually swarming with tommy-ruffs and pollack. We’d suggest saving this for a day with good slack water, as currents can pick up around here, but it’s absolutely worth the effort. For divers who appreciate a wreck with a real sense of history and structure, the Arfon is a standout dive.
