It would appear that Alexander Hall & Co. Ltd planned to install two lavatories on the starboard side of the ship next to the officer’s pantry.
What they don’t appear to have taken account of is the rather relevant fact that the outlet from these shunkies is about three feet below the waterline. A fact which they must have realised before launch as the outlets have been welded up.
As shown in this rather blurry shot.
I imagine there must have been a few red faces in Aberdeen when this was discovered.
