The Saint Prosper was once a cargo steamship built in 1920. The ship was transporting crude oil when, on March 8, 1939, it collided with a floating mine left after the Spanish Civil War (1936-1939). An explosion opened a large hole in the middle of the hull. The ship immediately sank and all 27 members of the crew died. The fire of burning oil was seen from the shore for hours. The wreck now lies in deep waters in the middle of the Bay of Rosses, and due to the depth of 60m/197ft, the dive is only suitable for very experienced or technical divers. Not only the extreme depths, but also fishing nets in this area can make this dive potentially dangerous.

When to go

It is possible to dive at this site all year round. However, during the winter the water temperature can drop down to as low as 13-14C/55-57F. The most comfortable diving conditions are during the summer, when the water temperature rises to 25-26C/77-79F.

What to see
