Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
691 lbs / 313 Kg = 13.1 x 4.7 " / 120 mm shells or 0.4 torpedoes
Stability (Unstable if below 1.00): 1.17
Metacentric height 1.6 ft / 0.5 m
Roll period: 12.9 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.59
Seaboat quality (Average = 1.00): 1.02
Hull form characteristics:
Hull has a flush deck
and transom stern
Block coefficient: 0.386
Length to Beam Ratio: 10.00 : 1
'Natural speed' for length: 22.89 kts
Power going to wave formation at top speed: 65 %
Trim (Max stability = 0, Max steadiness = 100): 69
Bow angle (Positive = bow angles forward): 30.00 degrees
Stern overhang: 5.00 ft / 1.52 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 19.00 ft / 5.79 m
- Forecastle (20 %): 17.00 ft / 5.18 m
- Mid (50 %): 15.50 ft / 4.72 m
- Quarterdeck (15 %): 14.50 ft / 4.42 m
- Stern: 14.00 ft / 4.27 m
- Average freeboard: 15.82 ft / 4.82 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 170.5 %
- Above water (accommodation/working, high = better): 108.7 %
Waterplane Area: 9,646 Square feet or 896 Square metres
Displacement factor (Displacement / loading): 78 %
Structure weight / hull surface area: 40 lbs/sq ft or 195 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.50
- Longitudinal: 1.64
- Overall: 0.56
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is adequate
Ship has slow, easy roll, a good, steady gun platform
