Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
4 192 lbs / 1 902 Kg = 4,2 x 14,0 " / 356 mm shells or 0,9 torpedoes
Stability (Unstable if below 1.00): 0,95
Metacentric height 2,0 ft / 0,6 m
Roll period: 17,4 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0,85
Seaboat quality (Average = 1.00): 1,40
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,603
Length to Beam Ratio: 4,90 : 1
'Natural speed' for length: 16,97 kts
Power going to wave formation at top speed: 37 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): -15,00 degrees
Stern overhang: 0,98 ft / 0,30 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 10,89 ft / 3,32 m
- Forecastle (20%): 10,89 ft / 3,32 m
- Mid (50%): 10,89 ft / 3,32 m
- Quarterdeck (15%): 10,89 ft / 3,32 m
- Stern: 10,89 ft / 3,32 m
- Average freeboard: 10,89 ft / 3,32 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 77,4%
- Above water (accommodation/working, high = better): 65,7%
Waterplane Area: 12 423 Square feet or 1 154 Square metres
Displacement factor (Displacement / loading): 97%
Structure weight / hull surface area: 178 lbs/sq ft or 870 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0,88
- Longitudinal: 3,21
- Overall: 1,00
Caution: Poor stability - excessive risk of capsizing
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is cramped
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily
