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) - U 1021 (POSSIBLY) offers some of Cornwall & Devon's richest wreck diving. Water ranges 10-18°C, warmest July, August, September.
We love a good mystery, and the U-1021 delivers. This isn’t a shallow, sun-dappled wreck; it’s a deep, dark dive at 48 metres, strictly for those comfortable with technical profiles and often chilly UK waters. Dropping down, you’ll feel the chill really bite, but the reward is worth it: a remarkably intact Type VIIC U-boat. Our favourite approach is to start midships, letting your eyes adjust to the gloom, then slowly moving forward. The conning tower is still prominent, a really eerie silhouette against the low visibility. You can make out the torpedo tubes if you’ve got a good torch and a keen eye. What really gets us about the U-1021 isn't just the history, though it's certainly there, a stark reminder of wartime, but how the sea has reclaimed it. Anemones speckle the hull like confetti, and we’ve often found conger eels peering out from open hatches, their heads like grizzled old men. Ling often patrol the deeper parts of the deck. This is a dive about quiet contemplation, about the sheer scale of the wreck emerging from the deep, and the resilient life that’s made a home on it. Don't rush it; take your time to really absorb the atmosphere.
