I have made some extensive changes to the design, but have managed to get the weight close to what the pictures tell. Note: the 6 in. guns should be in casemate mounts and then we could get ten guns, five mounts on each side. I did not make that change, but have tested it, and it works.

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):

Stability (Unstable if below 1.00): 1.40
Metacentric height 3.4 ft / 1.0 m
Roll period: 11.9 seconds
Steadiness - As gun platform (Average = 50 %): 99 %

Hull form characteristics:
Hull has a flush deck,
a normal bow and a cruiser stern
Block coefficient (normal/deep): 0.421 / 0.433
Length to Beam Ratio: 6.73 : 1
'Natural speed' for length: 18.71 kts
Power going to wave formation at top speed: 50 %
Trim (Max stability = 0, Max steadiness = 100): 59
Bow angle (Positive = bow angles forward): 20.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = length of deck as a percentage of waterline length):
Fore end, Aft end

- Above water (accommodation/working, high = better): 95.3 %
Waterplane Area: 11,355 Square feet or 1,055 Square metres
