I broke my record by missing the largest item yesterday, a 130m+ navy vessel. I dove in first time all OK. the second dive, after taking photo of 2 f**king crabs (pls excuse my language but they really were BTW), we lost this huge ship which should be just 10 metres away. After some hard swimming we almost got to deco limit and had to surface, bloody hell! I bring my compass every time but yesterday I jsut think, how can you miss this huge wreck? well yes I can..and my buddy is a well experienced cave diver!
at the bottom 5m+ is considered high vis in SA, often around 3m and can be <1 sometimes. I think we have 5m+ yesterday, even 10m+ at shallower water.
I think after taking the crabs photos, we were heading to the wrong direction, and when we went back, we were drifted by the currents and gone elsewhere. I think we are about 50m away the boat when surfaced, sounds close but that's hard swimming!
