Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
476 lbs / 216 Kg = 35.2 x 3.0 " / 76 mm shells or 0.3 torpedoes

- Recoil effect (Restricted arc if above 1.00): 0.11
Seaboat quality (Average = 1.00): 0.97
Hull form characteristics:
Hull has raised forecastle, rise forward of midbreak
and transom stern
Block coefficient: 0.425
Length to Beam Ratio: 10.32 : 1
'Natural speed' for length: 22.70 kts

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 201.0 %
- Above water (accommodation/working, high = better): 118.0 %
Waterplane Area: 9,576 Square feet or 890 Square metres
Displacement factor (Displacement / loading): 60 %
Structure weight / hull surface area: 35 lbs/sq ft or 170 Kg/sq metre
Hull strength (Relative):

Hull space for machinery, storage, compartmentation is extremely poor
Room for accommodation and workspaces is adequate
Ship has slow, easy roll, a good, steady gun platform
Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
