A third carrier hull as a royal yacht

How effective would a third Queen Elizabeth-class hull be as a royal yacht?

It could be an imposing royal yacht if finished with care, while a utilitarian conversion would waste much of its diplomatic value.

A third Queen Elizabeth-class hull converted into a royal yacht would be enormous, so its prestige would depend on how the conversion was finished. Graceful lines, a coherent superstructure, and appropriate fittings could turn the size into an effective diplomatic display. A lowest-bid finish would leave a conspicuous ship without the elegance expected of a national yacht. The hull could surpass other flagships in scale, but size alone would not make it an effective diplomatic symbol.
