Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
62,892 lbs / 28,527 Kg = 45.8 x 14.0 " / 356 mm shells or 11.0 torpedoes
Stability (Unstable if below 1.00): 1.14
Metacentric height 6.9 ft / 2.1 m
Roll period: 16.9 seconds
Steadiness - As gun platform (Average = 50 %): 51 %
- Recoil effect (Restricted arc if above 1.00): 0.67
Seaboat quality (Average = 1.00): 1.02
Hull form characteristics:
Hull has rise forward of midbreak
and transom stern
Block coefficient: 0.600
Length to Beam Ratio: 7.08 : 1
'Natural speed' for length: 31.79 kts
Power going to wave formation at top speed: 51 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 35.00 degrees
Stern overhang: 15.00 ft / 4.57 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 26.00 ft / 7.92 m
- Forecastle (20 %): 22.00 ft / 6.71 m
- Mid (70 %): 21.30 ft / 6.49 m (11.30 ft / 3.44 m aft of break)
- Quarterdeck (15 %): 12.00 ft / 3.66 m
- Stern: 13.00 ft / 3.96 m
- Average freeboard: 19.17 ft / 5.84 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 80.8 %
- Above water (accommodation/working, high = better): 147.4 %
Waterplane Area: 60,600 Square feet or 5,630 Square metres
Displacement factor (Displacement / loading): 102 %
Structure weight / hull surface area: 212 lbs/sq ft or 1,036 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.98
- Longitudinal: 1.23
- Overall: 1.00
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
