Boat-access wreck off Roche's Point with slack-water timing, a deep profile and busy fish life around the hull.
About UC42 Cork
UC42 Cork is a deep WWI submarine wreck in Cork Harbour, best approached at slack water because the harbour mouth can run hard. The wreck sits upright enough to show the conning tower, propellers and torpedo tubes, while conger eels, lobsters and schools of fish make the surrounding water feel busy. It is an advanced wreck dive rather than a sightseeing cruise, and respect for the site as a war grave matters as much as trim and gas planning.
