A heavy cruiser, where I've shamelessly plundered Swedish CDS and American cruisers and Aircraft carriers for inspiration(infact the conning tower was mostly a copy-paste-crop work of an older drawing of mine, but I really felt it fit well).

Waterplane Area: 27 316 Square feet or 2 538 Square metres
Displacement factor (Displacement / loading): 115 %
Structure weight / hull surface area: 121 lbs/sq ft or 589 Kg/sq metre
Hull strength (Relative):

Excellent machinery, storage, compartmentation space
Excellent accommodation and workspace room
I'm surprised I managed to squeeze in so much at such a modest displacement. Ah well, I'm not complaining.
Also, since I forgot to reply to the last comments:
Thanks, Hood, for the compliments. In fact I went for a German/French look, though I can see what you mean...
Deno: While the ideas are intriguing, I really don't feel any of the trade-offs are worth it.
