PLM 4 (POSSIBLY) - Cornwall & Devon

The PLM 4 is a proper historical dive, one we really enjoy. She’s a steamship, sunk by a German U-boat in 1917, and sits at 49 metres. Getting down there, you’ll often find the vis isn't what you’d call tropical, but that just adds to the atmosphere. We've spent many a dive finning over her decks, imagining the chaos of her final moments. The wreck itself is surprisingly intact for its age and location, offering some great penetration opportunities if you’re properly trained and equipped. Look out for conger eels peering from every dark recess; they’re practically residents. We’ve also seen some impressive pollack schooling above the main structure, and the occasional lobster tucked away in a crevice. It’s a dive for those who appreciate history and don't mind a bit of a challenge, a proper deep wreck experience for experienced divers.
