Hi all,
correct Graham, and the second dredger is Long Chau 2 (see uploaded photo) and also the 3 cargo vessel I have uploaded.

The vessel on the left looked familiar to me, and she is the Vietnamese LONG CHAU, formerly TRANSMUNDUM IV of 1971, and a sister vessel of TRANSMUNDUM VI which was based in South Wales from 1985 to 1997 as WELSH BAY.

Great place, we were there in the nineties, and used the anchor buoy for the LASH ships as base to do some swimming. I suspect these buoys may by now have been removed, and the number of hotels overlooking the bay may have multiplied as well.
