Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
10,677 lbs / 4,843 Kg = 41.7 x 8.0 " / 203 mm shells or 1.2 torpedoes
Stability (Unstable if below 1.00): 1.62
Metacentric height 4.8 ft / 1.5 m
Roll period: 10.9 seconds
Steadiness - As gun platform (Average = 50 %): 53 %
- Recoil effect (Restricted arc if above 1.00): 0.24
Seaboat quality (Average = 1.00): 1.06
Hull form characteristics:
Hull has low quarterdeck
and transom stern
Block coefficient: 0.550
Length to Beam Ratio: 10.07 : 1
'Natural speed' for length: 27.18 kts
Power going to wave formation at top speed: 58 %
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: 20.00 ft / 6.10 m
- Forecastle (20 %): 20.00 ft / 6.10 m
- Mid (50 %): 20.00 ft / 6.10 m
- Quarterdeck (20 %): 12.00 ft / 3.66 m (20.00 ft / 6.10 m before break)
- Stern: 12.00 ft / 3.66 m
- Average freeboard: 18.40 ft / 5.61 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 116.7 %
- Above water (accommodation/working, high = better): 192.3 %
Waterplane Area: 23,772 Square feet or 2,208 Square metres
Displacement factor (Displacement / loading): 117 %
Structure weight / hull surface area: 95 lbs/sq ft or 464 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 1.01
- Longitudinal: 1.24
- Overall: 1.03
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is excellent
