AGENORIA - Cornwall & Devon

The *Agenoria* isn't one of those wrecks that instantly wows you with an intact bow or stern. She’s more of a scatter, really, broken up by over a century of Atlantic storms. But that’s precisely why we love her. You’ll find her spread across a rocky seabed near Platte Rock, the metal plates and ribs draped in dead man’s fingers and bright anemones, giving the whole site a riot of colour you might not expect from a Cornish wreck. What you get here is a chance for some proper forensic diving. Pick a section, drop down, and spend your bottom time tracing what’s left of her. We've seen conger eels poking out from beneath the larger plates, and the cracks in the surrounding rock are often home to crabs and lobsters. Visibility here can be a bit hit or miss, typical for the area, but when it’s good, the light plays beautifully through the kelp, illuminating the rusty ironwork. This is a dive for those who enjoy exploration, who like to piece together a story from fragments. Not a deep dive, making it perfect for divers who want to take their time and really soak in the history.

Wreck History - AGENORIA

Year Sunk
1913
Vessel Type
schooner
Cause
grounding

The schooner Agenoria is one of hundreds of vessels claimed by the notoriously dangerous waters of the Channel Islands. In May 1913, she met her end near Platte Rock, falling victim to the region's formidable combination of massive tidal ranges, ferocious currents, and hidden granite reefs that have been a mariner's nightmare for centuries. Her sinking is a classic tale from an era of sail, a testament to the power of the sea that surrounds these islands.

Lying at a recreational depth of 15 meters, the remains of the Agenoria offer a poignant dive into history. While over a century of immersion has taken its toll, divers can still trace the outline of the wooden schooner and discover artifacts from her time. The site serves as a somber reminder of the area's rich maritime heritage, where every rock and reef tells a story. Exploring the Agenoria is not just about seeing a wreck; it's about connecting with the long history of those who sailed, and sometimes perished, in the Alderney Race and its surrounding channels.
