Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
2 252 lbs / 1 022 Kg = 13,3 x 7,1 " / 180 mm shells or 0,7 torpedoes
Stability (Unstable if below 1.00): 1,25
Metacentric height 2,1 ft / 0,6 m
Roll period: 12,4 seconds
Steadiness - As gun platform (Average = 50 %): 87 %
- Recoil effect (Restricted arc if above 1.00): 0,40
Seaboat quality (Average = 1.00): 1,75
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,531
Length to Beam Ratio: 6,63 : 1
'Natural speed' for length: 16,74 kts
Power going to wave formation at top speed: 49 %

Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 116,2%
- Above water (accommodation/working, high = better): 74,2%
Waterplane Area: 8 109 Square feet or 753 Square metres
Displacement factor (Displacement / loading): 92%
Structure weight / hull surface area: 77 lbs/sq ft or 377 Kg/sq metre
Hull strength (Relative):
