Miscellaneous weights: 100 tons, 18.2 %

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
103 lbs / 47 Kg = 215.4 x 1.0 " / 25 mm shells or 0.1 torpedoes

Roll period: 13.8 seconds
Steadiness - As gun platform (Average = 50 %): 7 %
- Recoil effect (Restricted arc if above 1.00): 0.00
Seaboat quality (Average = 1.00): 0.02

Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.503
Length to Beam Ratio: 7.50 : 1
'Natural speed' for length: 12.15 kts
Power going to wave formation at top speed: 59 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 30.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):

Waterplane Area: 1,618 Square feet or 150 Square metres
Displacement factor (Displacement / loading): 287 %
Structure weight / hull surface area: 113 lbs/sq ft or 551 Kg/sq metre

Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is extremely poor
Ship has quick, lively roll, not a steady gun platform
Caution: Lacks seaworthiness - very limited seakeeping ability

Diving depth = 400'
Emergency dive = 640
Crush depth = 1000'

A deck gun would probably be useful.

Indeed!
