Anne said: “[I have] very good memories of that trip… The journey out and the sea nannies that we had to stop us from launching ourselves over the side were very good memories… We were kept very busy.
“There was lots to do, all sorts of places to go and things to keep clean, lots of scrubbing and polishing, that was part of our role.”
