Volnay (21 metres)
Homeward from Canada with luxury goods and ammunition, this wreck detonated a contact mine on 14th December 1917 off the Manacles, and was bought into Porthallow bay and anchored a quarter of a mile off Porthkerris beach, where she sank in 21 metres onto a sandy bottom. It is a non-tidal, nice and easy wreck to dive. Although the wreck is well broken up, there are still some very large pieces, but the whole site is covered in a fine layer of silty sand so you must be careful not to stir things up. You may find some shell cases, lead balls or cordite if you're lucky.
