-I hope that my springsharp figures have improved... If not, please let me know. I am trying to find excuses for using it here. A lot of ships come out of springsharp as being really wet and unstable, not sure if the program is like that or what. Also, I have no idea how to use the freeboard mechanics so I just kind of let the program auto-design the figures based on the dimensions I put in...

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
11,419 lbs / 5,179 Kg = 13.2 x 12.0 " / 305 mm shells or 1.8 torpedoes
Stability (Unstable if below 1.00): 0.96
Metacentric height 2.9 ft / 0.9 m
Roll period: 18.1 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.63
Seaboat quality (Average = 1.00): 1.40
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.588
Length to Beam Ratio: 5.16 : 1
'Natural speed' for length: 19.44 kts
Power going to wave formation at top speed: 46 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 21.39 ft / 6.52 m

- Stern: 13.61 ft / 4.15 m
- Average freeboard: 14.23 ft / 4.34 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 78.9 %
- Above water (accommodation/working, high = better): 83.9 %
Waterplane Area: 20,043 Square feet or 1,862 Square metres
Displacement factor (Displacement / loading): 109 %
