Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
1.664 lbs / 755 Kg = 52,0 x 4,0 " / 102 mm shells or 0,5 torpedoes
Stability (Unstable if below 1.00): 1,67
Metacentric height 3,3 ft / 1,0 m
Roll period: 9,9 seconds
Steadiness - As gun platform (Average = 50 %): 54 %
- Recoil effect (Restricted arc if above 1.00): 0,05
Seaboat quality (Average = 1.00): 1,07
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0,489
Length to Beam Ratio: 8,62 : 1
'Natural speed' for length: 19,17 kts
Power going to wave formation at top speed: 60 %

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 164,9 %
- Above water (accommodation/working, high = better): 121,2 %
Waterplane Area: 10.339 Square feet or 961 Square metres
Displacement factor (Displacement / loading): 91 %
Structure weight / hull surface area: 61 lbs/sq ft or 296 Kg/sq metre
