Mind you those could be Ladies and Gents privies aft

The thought had occured to me as well......

The Privies is most probably correct, on some of the older TCC Craft the Privies looked like that although I suspect on the vessel featured one will be for Officers and the other for the also ran.
The John H Amos the Privie was part of the Paddlebox, when underway it was like sitting in a Waterfall with the noise on the Bulkhead from the Blades swishing around. No internal flushing of course it was a bucket over the side to collect the water for flushing purposes. Ron@?

Looks like the name is on the bow in white and is only 4/5 letters
Clue: Paul it's not TARDIS
