Stability (Unstable if below 1.00): 1.08
Metacentric height 3.0 ft / 0.9 m
Roll period: 15.7 seconds
Steadiness - As gun platform (Average = 50 %): 50 %
- Recoil effect (Restricted arc if above 1.00): 0.01
Seaboat quality (Average = 1.00): 1.73
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.556
Length to Beam Ratio: 7.38 : 1

- Stern: 16.00 ft / 4.88 m
- Average freeboard: 16.96 ft / 5.17 m
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 58.7 %
- Above water (accommodation/working, high = better): 86.1 %
Waterplane Area: 21,897 Square feet or 2,034 Square metres
Displacement factor (Displacement / loading): 205 %
Structure weight / hull surface area: 86 lbs/sq ft or 420 Kg/sq metre
