From a sketch for a GB/CB/1915 design

This is from a pencil sketch with weights for a GB/CB/1915 design. The advantage of using it is that there are armour lengths explicitly specified. One thing that is immediately obvious is that the hull weight I had originally hoped for was too low, by a great deal. This was intended to have about a 26ft draft and be 35,000 tons, standard. The actual Springsharp report turned out differently:

GB/CB/1915 variant, Great Britain Battlecruiser laid down 1915 (Engine 1921)

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   55,959 lbs / 25,382 Kg = 33.2 x 15.0 " / 381 mm shells or 6.8 torpedoes

  - Above water (accommodation/working, high = better): 252.7 %
 Waterplane Area: 66,591 Square feet or 6,187 Square metres
