Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
7.556 lbs / 3.428 Kg = 73,4 x 5,9 " / 150 mm shells or 1,2 torpedoes
Stability (Unstable if below 1.00): 1,20
Metacentric height 2,4 ft / 0,7 m
Roll period: 13,3 seconds
Steadiness - As gun platform (Average = 50 %): 57 %
- Recoil effect (Restricted arc if above 1.00): 0,41
Seaboat quality (Average = 1.00): 1,14
Hull form characteristics:
Hull has low quarterdeck
Block coefficient: 0,487
Length to Beam Ratio: 10,33 : 1
'Natural speed' for length: 22,55 kts
Power going to wave formation at top speed: 54 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 10,00 degrees
Stern overhang: 0,00 ft / 0,00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 19,69 ft / 6,00 m
- Forecastle (20 %): 16,40 ft / 5,00 m
- Mid (50 %): 16,40 ft / 5,00 m
- Quarterdeck (15 %): 13,12 ft / 4,00 m (16,40 ft / 5,00 m before break)
- Stern: 13,12 ft / 4,00 m
- Average freeboard: 16,17 ft / 4,93 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 103,5 %
- Above water (accommodation/working, high = better): 122,3 %
Waterplane Area: 16.480 Square feet or 1.531 Square metres
Displacement factor (Displacement / loading): 108 %
Structure weight / hull surface area: 85 lbs/sq ft or 413 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,96
- Longitudinal: 1,40
- Overall: 1,00
Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is excellent
Armor is on the thick side and belt is not deep enough imho. 6" can withstand 8-9" shells from the distance, but the ship won't damage ships with such armament. I don't think you need upper belt, either.
