Here's the data for the royal yacht, with some additional detail added in. Note that the torpedo tubes - installed at the instance of the Rana - have not been publically reported, and are known to just a handful of people outside the ship's crew.

in the heaviest weather.
Magazines and engineering spaces are roomy, with superior
watertight subdivision.
Ship is roomy, with superior accommodation and working space.
