The Leith Shipyards of Henry Robb built only the one ship for Trinity House, but what a vessel.
The PATRICIA was at the time built to fulfill two roles one being as a light house/bouy tender and the other as a temporary replacement ship for the Royal Yacht Britannia.
With her gold plated taps and 3" (75mm) thick pile carpet, she really was a bit above your normal commercial vessel.
The thinking at the time was with the Britannia being retired and while the Royal family waited on a replacement ship (never happened) the THV PATRICIA would "just have to do in the meantime".

As a strange twist of fate the Royal Yacht Britannia is now berthed at the quayside which used to be the quay where Henry Robb built ships were out fitted, she is now one of the top tourist attractions in Scotland.
