I was at Stanley from Dec 82-May 83, and was living on the Rangatira in Stanley Harbour. We had to get to and from the airfield everyday, by landing craft to the Stanley Jetty, and then trucks to the airfield. I say Stanley jetty, but not sure of the names for them all, but it was the main one with the shop just of to the left, as you got off the jetty. I can't recall seeing anything bigger than a landing craft using that jetty. The Tristram was tied up to the left, East, of that jetty, didn't ever hear it called anything, for the time I was there. There was a sort of beachhead landing area a bit further to the East of the Tristram, and I seem to recall it was quite busy and was used to land stuff of the mexifloat craft. It was quite impressive watching the Eager Beavers unloading cargo from them, and negotiating the slope, to load lorries.
(I say that we used to use the landing craft everyday to/from work, but one day the sea was to rough, and we had to use the company helicopter.)
