Superb vis! Could actually see the surface from the bottom. The plan was to return to the shot line when we got to 70 bar, but we could practically see the shot line throughout the dive. Most notable feature of the wreck was its boiler, full of holes about 2 cm in diameter which served to let steam out originally. Also saw a conga eel lurking under a beam, and I kept well clear of it. This was a thoroughly enjoyable dive - the first time I could actually identify the wreck I was diving on as a ship.
