Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     71,217 lbs / 32,303 Kg = 42.5 x 15.0 " / 380 mm shells or 13.4 torpedoes
   Stability (Unstable if below 1.00): 1.22
   Metacentric height 9.3 ft / 2.8 m
   Roll period: 16.3 seconds
   Steadiness   - As gun platform (Average = 50 %): 51 %

   Seaboat quality  (Average = 1.00): 1.02

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.572
   Length to Beam Ratio: 6.67 : 1
   'Natural speed' for length: 28.06 kts

   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 80.3 %
      - Above water (accommodation/working, high = better): 177.9 %
   Waterplane Area: 66,229 Square feet or 6,153 Square metres
   Displacement factor (Displacement / loading): 111 %
   Structure weight / hull surface area: 198 lbs/sq ft or 965 Kg/sq metre

  it's good to plan ahead  :D

  nicely balanced - but could consider:

    trading-off some stability for higher steadiness?

   heavier sec guns vs quite heavy armour protection on them

Laid down in 1930...

We shall not see this monster before 14 years ...

ahahaahhahaha...nope, looks like then end will be around Dec1920-Jan1921. Besides, I dont have any of the guns for this thing right now, or the slipway, or engine tech. You think all that would get done with the war going on?

I'm sure the RRC would love it if you built this thing during wartime. Every IC going into her is one that isn't going into winning a war.
