Well, since HMS Princess Royal was NOT "known as the Gin Palace", then I suppose it was nothing.
HMS Agincourt (ex-Rio de Janeiro) is the ship that carried that moniker... A gin court of course!
To be frank, can you verify with 100% certainty that the Princess Royal was not nicknamed the Gin Palace? Just because you can't find it on the internet doesn't mean it wasn't...
(your posts and use of bold always suggests you're angry that someone dare get it wrong, Green knight)
This will probably never be able to be verified, certainly not by me as I'm over 1,000 miles away from where I read it and it was a very long time ago, so I'm digging it out of the recesses of my memory, I read that was the case (maybe another ship that Beatty frequently was found aboard if not the Princess Royal, then?) in a personal account in an archive in a museum in Scotland, - it was definitely NOT the Agincourt (that's everywhere on the interweb, so is easy to find) that was being discussed but was associated with Beatty at Rosyth.
That same year at the museum I was fortunate to meet a woman in her 90s who was a child during the latter half of the Great War and used to play at this air station, where her family was based and the RNAS had airships, and the Furious' aircraft squadron was based. She remembered seeing these magnificent craft in their natural habitat, which was something. I remember showing her albums filled with fantastic shots of these things...
