REDLINE NO.1 - Cornwall & Devon

The Redline No.1 is a proper deep dive, sitting at 51 metres, making it one for experienced tech divers with the right kit. This tanker, built just a year before she sank in 1925, flipped over in a nasty storm off Trevose Head. We love a wreck with a story, and the Redline’s is a tragic one, taking nine lives with her. When you drop down, the visibility in this part of the Channel can be hit or miss, but on a good day, the wreck reveals herself slowly from the gloom. She’s not massive, 36.6 metres long, but what’s left is surprisingly intact in places, considering the weather that sank her. We’d suggest focusing your exploration on the midships, where the structure is most defined, and you often find the best invertebrate life – colourful jewel anemones clinging to the plates, and often a conger eel or two peeking from a dark hole. It’s a quiet, atmospheric dive, perfect for those who appreciate history and the slow reclamation of steel by the sea.
