The Katja was a 185nt, 45 metre, diesel-engined cargo ship built in Germany in 1949. She hit a reef in November 1964. The stern broke off and sank shortly afterwards, followed by the bows a few days later.
The wreck lies SE/NW at 20m in a sandy gully between two rocky ridges. The stern section is upright and reasonably intact. A variety of sinks and toilets can be seen inside the hull. An anchor lies against the port side of the forward part of the stern section. There is a jumble of plates and girders in the rocks on the starboard side, alongside and forward of the stern section. This is presumably the remains of the bows.
Somewhere in the vicinity of the wreck there should also be a video camera and housing (flooded) complete with a perfectly good set of lights. It was hurled overboard by its owner, one of our group in 2003, in a moment of madness.
