Porthkerris is the normal launch point for the wreck.
The Mohegan is a broken 1898 ocean-liner wreck on the Manacles, reached by a short boat ride from Porthkerris. The wreck sits mostly in the low-to-mid 20s and rewards a slack-water plan, with girders, boilers, and reef features above the hull making the route easy to read. Gorgonian fans, Dead Man's Fingers, and jewel anemones add life, while conger eels and anglerfish show up around the wreck and sand.
