ST JACQUES (PROBABLY) - Cornwall & Devon

The ST JACQUES, probably, sits at 33 metres, a steamship sunk by a German sub in 1917. She’s definitely a dive for those comfortable with deeper wrecks and a bit of chill. We’ve found her to be quite broken up, but you can still pick out the triple-expansion engine and the stern section. Look carefully and you’ll spot plumose anemones waving from crevices and a decent population of crabs scuttling over the plates. Visibility can be a bit variable, but on a good day, the scale of her 88-metre length is impressive. This site is less about intact structures and more about exploring a piece of history colonised by the sea.
