SAINT RONAIG - Cornwall & Devon

The Saint Ronaig is exactly what we love in a shallow wreck dive: accessible, atmospheric, and full of life. This 50-metre motor vessel, torpedoed in 1940, lies broken but still recognisable at just 10 metres, making it perfect for extended bottom times and even new wreck divers. We always find ourselves drawn to the stern, where the prop shaft is still visible, and the hull plates are draped in plumose anemones, their white tentacles waving gently in the surge. Look closely in the nooks and crannies for squat lobsters, and we’ve spotted dogfish tucked into the sand nearby on more than one occasion. It’s a site that really comes alive when there’s a bit of sun, filtering through the green water and illuminating the coalfish darting amongst the twisted metal. It’s not a deep, dramatic wreck, but its historical context and the sheer amount of life that has claimed it make it a firm favourite of ours.
