When I was a kid in Demport, I used to walk around Mount Wise most evenings. There was a pier where a couple of Admiral's barges were kept. One was green and the other was dark blue. I used to know the answer to this, but age (and a lot of drink) have dimmed the memory cells somewhat. Was one for the local C-in-C, and the other for the Admiral Superintendent, or what ? Been bugging me for a couple of days now. And if anyone remembers his barges being taken for a ride in the 50s/60s, I know who it was - revealed by an old salt in our hotel in Cardiff 1972 !!
