This design comes from a discussion with myself and Brockpaine some time ago. He pointed out that an 8x12'' ship is has enough Quality for it to be effective at Quantity.
This ship is a war build construct utilizing older 12'' guns and having more speed that older Battleships.
Build for WWI it will become mainstay BB for WWII.

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
37 340 lbs / 16 937 Kg = 43,2 x 12,0 " / 305 mm shells or 6,9 torpedoes
Stability (Unstable if below 1.00): 1,10
Metacentric height 5,9 ft / 1,8 m
Roll period: 17,0 seconds
Steadiness - As gun platform (Average = 50 %): 57 %
- Recoil effect (Restricted arc if above 1.00): 0,52
Seaboat quality (Average = 1.00): 1,30
Hull form characteristics:
Hull has rise forward of midbreak
Block coefficient: 0,550
Length to Beam Ratio: 5,90 : 1
'Natural speed' for length: 24,10 kts
Power going to wave formation at top speed: 49 %
Trim (Max stability = 0, Max steadiness = 100): 44
Bow angle (Positive = bow angles forward): 50,00 degrees
Stern overhang: 0,00 ft / 0,00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 24,61 ft / 7,50 m
- Forecastle (22%): 19,69 ft / 6,00 m

Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 84,7%
- Above water (accommodation/working, high = better): 138,6%
Waterplane Area: 39 889 Square feet or 3 706 Square metres
Displacement factor (Displacement / loading): 103%
Structure weight / hull surface area: 184 lbs/sq ft or 900 Kg/sq metre
Hull strength (Relative):

- Longitudinal: 1,68
- Overall: 1,00
Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is excellent
Good seaboat, rides out heavy weather easily
apologies for the type'O I'm drunk again
