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

Hull form characteristics:
Hull has rise forward of midbreak
and transom stern
Block coefficient: 0.550
Length to Beam Ratio: 10.00 : 1
'Natural speed' for length: 30.49 kts
Power going to wave formation at top speed: 52 %
Trim (Max stability = 0, Max steadiness = 100): 57
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 29.86 ft / 9.10 m
- Forecastle (25 %): 28.22 ft / 8.60 m
- Mid (50 %): 26.57 ft / 8.10 m (16.40 ft / 5.00 m aft of break)
- Quarterdeck (15 %): 16.40 ft / 5.00 m

- Above water (accommodation/working, high = better): 204.2 %
Waterplane Area: 37,852 Square feet or 3,517 Square metres
Displacement factor (Displacement / loading): 135 %
Structure weight / hull surface area: 127 lbs/sq ft or 619 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.99
- Longitudinal: 1.13
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily
Notes:
155 tons per twin turret - 465 tons saved in total.
I'm curious as to what the 4x2 version looks like. If they are all in one fleet having three ships with 4x2 rather than four ships of 3x2 shouldn't really matter if you can produce something a little tougher in the armour department.
