Why dive here
With 176+ marine species recorded in the area - including blue sharks, dolphins, dwarf minke whales, humpback whales and ocean sunfish (mola mola) - Louis Shield offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
The Louis Shield, a trawler lost to a mine in 1943, sits upright and largely intact, making it one of our favourite wreck dives in the region. Dropping down, the hull looms out of the gloom, often cloaked in plumose anemones that sway gently with the surge. We love tracing the deck, seeing the large prop still in place, and imagining the scene of its final moments. Penetration is possible for trained wreck divers, with the engine room a particular highlight, though even a circumnavigation offers plenty to explore. Conger eels peer from every gap, their thick bodies disappearing into the darkness of the holds, and often a grumpy anglerfish can be spotted hunkering down amongst the debris on the seabed. Best dived on slack water to avoid strong currents, this site offers a real connection to wartime history and a fantastic home for Cornwall’s resident marine life. It’s a rewarding dive for those comfortable in deeper water and with some wreck experience.
