Uwe, I like your thinking--it adds a bit of "time and technology march on" and some differences that are reasons to choose one ship over another. If memory serves, Ocean was enough bigger than her unstretched sisters to cross the 2100t barrier, and then there's the matter of post-plug HMS Prince.

I think you have Stats Committee potential, and if you're interested I'll ask for a vote on inviting you to join so that you can see all our prior work for ideas--though the only one we successfully pushed down the ways was Tonnant, and even that was only meant as an "interim" until Ares launched theirs.
