Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):

Roll period: 13.7 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.60
Seaboat quality (Average = 1.00): 1.21

Hull form characteristics:
Hull has rise forward of midbreak
and transom stern
Block coefficient: 0.482
Length to Beam Ratio: 11.13 : 1
'Natural speed' for length: 26.55 kts
Power going to wave formation at top speed: 56 %

- Longitudinal: 1.23
- Overall: 0.81
Caution: Hull subject to strain in open-sea
Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily

Aside from the usual gripe about the quantity of AA...
;-)

What about 4x2 152mm guns instead? And less deck armour.

I'd personally stick with the current main armament layout. More deckspace and 1 more gun to boot.

18 - 2.24" (6x3 guns) seems a tad bit too much though for a 6000 ton CL, those 23.6" torpedoes will take up lots of space.

The Iberian (aka Bernhard's) idea of the 57mm guns as a dual purpose weapon, good against MTB's as well as Aircraft,
so i don't think 18 single shot weapons is too much.

Maybe, but the triple seems to be an Iberian thing like the 57mm, and I need to keep a few "points of difference" between my Danish and Iberian designs

I have an Idea as to how to get around that!
