ARCTIC PIONEER - Cornwall & Devon

The Arctic Pioneer, a trawler sunk by a mine in 1942, sits upright at a modest 10 metres. We love that you can see almost the entire wreck in one dive, with plenty of time to poke around. Her superstructure is broken, but the bow and stern are still distinct, creating lots of nooks for conger eels and squat lobsters. We'd suggest aiming for a slack tide; the currents here can whip up and turn the visibility milky, but on a good day, you're rewarded with light shafts filtering through the collapsed deck plates onto colourful jewel anemones. It's an ideal spot for newer wreck divers or those wanting a relaxed potter, and our favourite feature has to be the huge propeller, often covered in dead man's fingers.

The Arctic Pioneer was a large, powerful steam trawler built in 1936, designed to withstand the harsh conditions of fishing in the North Atlantic. With the outbreak of World War II, her robust build made her a prime candidate for military service. She was requisitioned by the British Admiralty, armed, and designated His Majesty's Trawler (HMT) Arctic Pioneer. Her new mission was to patrol the English Channel, hunting for enemy submarines and protecting vital Allied shipping lanes.

On May 27th, 1942, her wartime service came to a violent end. While on patrol off the Cornish coast, HMT Arctic Pioneer struck a German-laid mine. The resulting explosion was devastating, and the ship sank almost immediately with the loss of most of her crew. Her sinking was a tragic but common story during the Battle of the Atlantic, where the waters around the UK were a constant, invisible battlefield.

Today, the wreck of the Arctic Pioneer lies in 10 meters of water, serving as a poignant memorial to her crew. The mine explosion and subsequent salvage work have left the wreck heavily broken and scattered, with the ship's massive boilers being the most prominent and recognizable feature. Classified as a 'Dangerous Wreck' due to its shallow depth, it presents a hazard to shipping but an interesting site for divers. Exploring the debris field offers a direct connection to the naval history of the Second World War, a shallow dive that is rich in historical significance.
