Historic Portivy wreck with strong structure and marine life.
Historic Portivy wreck with strong structure and marine life.
This is a local wreck dive run from Portivy, so day-of operator guidance matters.
The Nann Smith is a Norwegian cargo shipwreck that sank in 1917 after striking a mine while carrying iron ore. The wreck lies on the seabed with boilers standing proud and much of the structure still clearly visible. Marine growth and resident fauna make it a rich wreck dive, best approached as a boat outing from the Portivy side of Quiberon within the local wreck circuit.
