The Mohegan (Wreck)

Just a ten-minute journey from Porthkerris, you'll find The Mohegan. This magnificent luxury liner, measuring 482ft and weighing 6,889 gross tons, met a mysterious fate when it collided with the Manacles in 1898. Diving the Mohegan requires careful timing, as it is best explored during slack tide or weak neap tides.

Underneath the water's surface, a vibrant ecosystem awaits. Gorgonian fans, Dead Man's Fingers, jewel anemones, conger eels, flatfish, and angler fish populate the area. Every year, divers still discover a few precious artifacts belonging to the passengers.

With a minimum depth of 16m and a maximum depth of 24m, the wreckage of the Mohegan beckons to advanced divers. The steam liner, weighing an astonishing 6,889 tons, crashed into the Manacles on October 14th, 1898, embedding its rudder into the rock and tearing open its hull. Within just 12 minutes, the ship sank, claiming the lives of 106 individuals. However, some lucky passengers were rescued by a Porthoustock lifeboat. To pay homage to the victims, you can visit their mass grave at St Keverne churchyard. The Atlantic Transport Line even dedicated a beautiful stained glass window in their memory.

As you descend into the water, visibility reaches up to 7m, offering a clear view of the stunning underwater landscape. Located near Minstrel Rock, Porthoustock, Cornwall, England, TR12 6QW, United Kingdom, this dive site provides a thrilling and historical adventure for divers with the necessary expertise.
