I have seen this image a few places but I think relevant
And a couple of comments from the post I linked to earlier
when I was at 17 P&M years later there was a great story about a mexe cox’n during this period moving civilian plant equipment ashore in slightly lumpy seas; the digger or whatever it was shifted on deck and simply slipped over the edge into the oggin whilst the mexe continued serenely on. For whatever reason the cox’n simply tried to bluff it out when questioned later about the missing kit, claiming he couldn’t remember whether it had been loaded or not
and a follow up to that one
Have read the vessel logbook you are on about the vehicles were called haulmatics but were soon renamed aquamatics!!! according to the logbook they were recovered and eventually returned to service
