BEN BLANCHE - Cornwall & Devon

We’ve always had a soft spot for the Ben Blanche, a little iron steamship that went down in 1931. It’s a shallow dive, maxing out at three metres, which makes it perfect for a relaxed second dive or when the weather's a bit choppy further out. What we love here is how the wreck, despite its age, still holds its shape surprisingly well. You can trace the lines of the hull, parts of the superstructure, and even the single boiler. Our favourite time to visit is on a slack tide, with a bit of sunshine filtering down; the light plays beautifully on the rust-coloured metal. Schools of juvenile pollack often use the wreck for shelter, darting in and out of the crevices. We’ve also spotted plenty of dogfish nestled amongst the plates, and the anemones here are particularly vibrant, speckling the ironwork with colour. It’s a gentle exploration, a real step back in time, and just a genuinely peaceful place to spend an hour underwater. This spot is definitely one for those who appreciate history and don't need roaring currents or deep drops to enjoy a dive.

Cause
grounding

The SS Ben Blanche began her life in 1891 as the Sarah Blanche, an iron-hulled steamship built by J. Fullerton & Co. For over 40 years, this modest vessel, powered by a 55-horsepower compound steam engine, reliably transported goods around the British Isles. Her story is one of routine maritime commerce, a stark contrast to the dramatic end she would meet off the rugged Cornish coast.

In December 1933, the Ben Blanche was caught in a severe gale. Battered by fierce winds and massive waves, she was driven ashore and wrecked. Today, her remains lie scattered in just 3 meters of water, making her one of the most accessible wrecks in the region. This shallow depth means the site can be explored by novice divers, freedivers, and even snorkelers on a calm day. Over the decades, the sea has flattened much of her structure, but divers can still identify her boiler, engine components, and sections of iron hull plating, all now colonized by kelp and home to a variety of coastal marine life.
