I had an alternate design for the GB/BB/1915 battleship

In 2002, I had an alternate design and look for the GB/BB/1915 battleship. The look was like the Hood, except for a flush deck and triple turrets. The displacement was planned to be 70,000 tons, but Springsharp doesn't think that much displacement is necessary, so it comes out considerably lighter:

GB/BB/1915 alternate 1, GB/BB/1915 Battleship laid down 1915 (Engine 1927)

 Armour: 23,503 tons, 37.1 %
    - Belts: 6,185 tons, 9.8 %
    - Torpedo bulkhead: 1,709 tons, 2.7 %
    - Armament: 5,112 tons, 8.1 %
    - Armour Deck: 9,880 tons, 15.6 %
    - Conning Tower: 617 tons, 1.0 %
 Machinery: 2,873 tons, 4.5 %

 Miscellaneous weights: 0 tons, 0.0 %

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   88,362 lbs / 40,080 Kg = 22.1 x 20.0 " / 508 mm shells or 15.4 torpedoes

 Metacentric height 10.7 ft / 3.2 m
 Roll period: 17.4 seconds
 Steadiness - As gun platform (Average = 50 %): 73 %
   - Recoil effect (Restricted arc if above 1.00): 0.56
 Seaboat quality  (Average = 1.00): 1.46

Hull form characteristics:
 Hull has a flush deck
 Block coefficient: 0.563
 Length to Beam Ratio: 5.93 : 1
 'Natural speed' for length: 28.28 kts
 Power going to wave formation at top speed: 44 %
 Trim (Max stability = 0, Max steadiness = 100): 50
 Bow angle (Positive = bow angles forward): 2.00 degrees
 Stern overhang: -1.00 ft / -0.30 m
 Freeboard (% = measuring location as a percentage of overall length):
    - Stem:  30.00 ft / 9.14 m

    - Stern:  23.00 ft / 7.01 m
    - Average freeboard: 23.83 ft / 7.26 m
 Ship tends to be wet forward

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 82.3 %
  - Above water (accommodation/working, high = better): 169.1 %
 Waterplane Area: 76,297 Square feet or 7,088 Square metres
