Firstly, every single trade or rate badge used by the RN was also made in a white-on-blue version for Royal Yacht personnel. All the crew were volunteers and could be from any branch and any rate, so the variety of badges available is virtually limitless!

Good Conduct badges were also made in white-on-blue.

And I have example of each of the King's Crown 'Royal Yacht' titles issued - red-on-blue and gold-on blue. These were in use between 1927 and 1951. I will post some images of mine if you are interested.
