A new iteration based from discussion with Blackbuck in the IRC based on a reduced scale Dante Alighieri adopting three triple turrets instead of four twins in crude photoshoped SB scale;

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
24,796 lbs / 11,247 Kg = 36.3 x 11.1 " / 282 mm shells or 3.3 torpedoes
Stability (Unstable if below 1.00): 1.10
Metacentric height 4.1 ft / 1.2 m
Roll period: 16.0 seconds
Steadiness - As gun platform (Average = 50 %): 90 %
- Recoil effect (Restricted arc if above 1.00): 0.97
Seaboat quality (Average = 1.00): 1.79
Hull form characteristics:
Hull has raised forecastle,
a ram bow and a cruiser stern
Block coefficient (normal/deep): 0.563 / 0.572
Length to Beam Ratio: 6.17 : 1
'Natural speed' for length: 21.79 kts
Power going to wave formation at top speed: 47 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 2.00 ft / 0.61 m
Freeboard (% = length of deck as a percentage of waterline length):
Fore end, Aft end
- Forecastle: 21.60 %, 28.00 ft / 8.53 m, 28.00 ft / 8.53 m
- Forward deck: 30.00 %, 20.00 ft / 6.10 m, 20.00 ft / 6.10 m

- Quarter deck: 15.00 %, 20.00 ft / 6.10 m, 20.00 ft / 6.10 m
- Average freeboard: 21.73 ft / 6.62 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 62.9 %
- Above water (accommodation/working, high = better): 145.4 %
Waterplane Area: 25,836 Square feet or 2,400 Square metres
Displacement factor (Displacement / loading): 116 %
Structure weight / hull surface area: 150 lbs/sq ft or 732 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.90
- Longitudinal: 2.53
- Overall: 1.00
Excellent machinery, storage, compartmentation space
Excellent accommodation and workspace room
Ship has slow, easy roll, a good, steady gun platform
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
I'm actually rather fond of this design. With some tweaks it could potentially work as a reasonable CDS and baby dreadnought.
