BETTANN (STERN SECTION) - Cornwall & Devon

The Bettann’s stern section, resting at a gentle 13 metres, is one of our go-to wreck dives when we’re in Cornwall. It’s a proper piece of history, scuttled back in ‘67 after being chopped in half during salvage. We love how the bow lies elsewhere, making this a distinct, explorable chunk. You can really get a feel for the ship’s guts here. Drop down and you're met with substantial plates and beams, now home to clouds of jewel anemones, all oranges and purples that glow in your torch beam. Conger eels, some surprisingly large, peer from nooks in the collapsed superstructure, their heads thick as your arm. If you take your time and really look, you'll spot scorpion fish camouflaged against the rust, perfectly still. This site is brilliant for wreck fanatics who appreciate a bit of backstory, and for photographers keen on colourful macro life against a dramatic, decaying backdrop. It’s not a deep dive, making bottom time plentiful for a good, thorough explore.

Wreck History - BETTANN (STERN SECTION)

Year Sunk
1967
Vessel Type
cargo ship
Cause
foundered

The motor vessel Bettann met her end on January 19th, 1967, after taking on water and sinking while at anchor in St Helen's Roads. The wreck was deemed a navigational hazard, and a salvage operation was launched to remove it. To facilitate this, the ship was cut into two distinct sections, creating two separate wreck sites that divers can explore today.

While the bow section sank into deeper water, the stern of the Bettann now rests in a much more accessible depth of just 13 metres. This makes it an ideal dive for novice wreck divers or those looking for a longer, more relaxed exploration. Divers can explore the aft superstructure and imagine the final moments of this vessel before she was split in two. The shallow depth allows for excellent light penetration on a clear day, illuminating the marine life that now calls the Bettann's stern home.
