Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
3,902 lbs / 1,770 Kg = 13.8 x 8.3 " / 210 mm shells or 0.7 torpedoes
Stability (Unstable if below 1.00): 1.18
Metacentric height 2.3 ft / 0.7 m
Roll period: 13.5 seconds
Steadiness - As gun platform (Average = 50 %): 100 %
- Recoil effect (Restricted arc if above 1.00): 0.76
Seaboat quality (Average = 1.00): 2.00
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.568
Length to Beam Ratio: 9.37 : 1
'Natural speed' for length: 21.43 kts
Power going to wave formation at top speed: 44 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): -12.00 degrees
Stern overhang: -5.20 ft / -1.58 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 21.57 ft / 6.57 m
- Forecastle (20 %): 20.00 ft / 6.10 m
- Mid (50 %): 20.00 ft / 6.10 m
- Quarterdeck (15 %): 20.00 ft / 6.10 m
- Stern: 20.00 ft / 6.10 m
- Average freeboard: 20.13 ft / 6.13 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 145.2 %
- Above water (accommodation/working, high = better): 178.5 %
Waterplane Area: 15,975 Square feet or 1,484 Square metres
Displacement factor (Displacement / loading): 98 %
Structure weight / hull surface area: 82 lbs/sq ft or 400 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.91
- Longitudinal: 2.33
- Overall: 1.00
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
Excellent seaboat, comfortable, can fire her guns in the heaviest weather
Design works well but couldn't fit a torpedo bulkhead and the belt is shorter than I'd like. A bit more speed would also be nice.
