Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     61,534 lbs / 27,911 Kg = 74.7 x 11.8 " / 300 mm shells or 8.9 torpedoes
   Stability (Unstable if below 1.00): 1.22
   Metacentric height 7.1 ft / 2.2 m
   Roll period: 15.6 seconds
   Steadiness   - As gun platform (Average = 50 %): 77 %

   Seaboat quality  (Average = 1.00): 1.54

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.727

   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 82.4 %
      - Above water (accommodation/working, high = better): 217.9 %
   Waterplane Area: 56,993 Square feet or 5,295 Square metres
   Displacement factor (Displacement / loading): 111 %

Sorry, but i kind of fail to see the point?
Is it a design you feel you should have built instead of the ones you got?

Yeah, pretty much. Three guns more per broadside, superior armor, a torpedo belt (I kick myself every time I think about that), nearly as tough, and yet equal or greater in their other qualities... a better design all around, I feel.

Shift it's year laid down, and start making new battleships it an improved version of this design then.
