Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
807 lbs / 366 Kg = 7.1 x 6.1 " / 155 mm shells or 0.2 torpedoes
Stability (Unstable if below 1.00): 1.11
Metacentric height 1.5 ft / 0.5 m
Roll period: 13.5 seconds
Steadiness
- As gun platform (Average = 50 %): 68 %
- Recoil effect (Restricted arc if above 1.00): 0.35
Seaboat quality (Average = 1.00): 0.77
Hull form characteristics:
Hull has rise forward of midbreak,
a normal bow and small transom stern
Block coefficient (normal/deep): 0.466 / 0.474
Length to Beam Ratio: 12.42 : 1
'Natural speed' for length: 23.56 kts
Power going to wave formation at top speed: 58 %

Ship tends to be wet forward
Ship space, strength and comments:
Space
- Hull below water (magazines/engines, low = better): 155.6%
- Above water (accommodation/working, high = better): 114.3%
Waterplane Area: 12,734 Square feet or 1,183 Square metres
Displacement factor (Displacement / loading): 80%
Structure weight / hull surface area: 41 lbs/sq ft or 201 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.63
- Longitudinal: 0.48
- Overall: 0.51
Cramped machinery, storage, compartmentation space
Adequate accommodation and workspace room
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
