Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
792 lbs / 359 Kg = 11,8 x 5,1 " / 130 mm shells or 0,3 torpedoes
Stability (Unstable if below 1.00): 1,10
Metacentric height 1,1 ft / 0,3 m
Roll period: 13,0 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0,91
Seaboat quality (Average = 1.00): 1,12
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,455
Length to Beam Ratio: 12,00 : 1
'Natural speed' for length: 19,84 kts
Power going to wave formation at top speed: 63 %
Trim (Max stability = 0, Max steadiness = 100): 63
Bow angle (Positive = bow angles forward): 6,00 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 %): 14,76 ft / 4,50 m
- Mid (50 %): 14,76 ft / 4,50 m
- Quarterdeck (15 %): 14,76 ft / 4,50 m
- Stern: 14,76 ft / 4,50 m
- Average freeboard: 15,16 ft / 4,62 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 167,1 %
- Above water (accommodation/working, high = better): 132,9 %
Waterplane Area: 8 273 Square feet or 769 Square metres
Displacement factor (Displacement / loading): 77 %
Structure weight / hull surface area: 46 lbs/sq ft or 225 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,63
- Longitudinal: 2,11
- Overall: 0,71
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
