YVONNE - Cornwall & Devon

We love a good wreck with a story, and the *Yvonne* has over a century of them. Sunk in 1920, this steel sailing vessel lies at a comfortable 6m, making it one of Cornwall’s most accessible wrecks. You don't need to be an advanced diver to appreciate its scale; at 68m long, the outline is still clear, spread across the seabed. Dropping onto the *Yvonne*, you're immediately struck by how much of the original structure remains – the bow and stern sections are particularly distinct. We’ve found the stern often holds the most interest, with crabs scuttling into crevices and lobsters peeking from beneath plates of steel. Look closely at the ribs of the hull, now draped in soft corals and anemones, creating miniature ecosystems. The ambient light at this depth means colours truly pop, even on a grey Cornish day. For photographers, a wide-angle lens is perfect to capture the sheer size and the way light filters through the kelp forest that dances above the wreck. It’s a gentle dive, perfect for extending bottom time and really soaking in the history.
