633 lbs / 287 Kg = 10.1 x 5.0 " / 127 mm shells or 0.4 torpedoes

Stability (Unstable if below 1.00): 1.07

Metacentric height 1.2 ft / 0.4 m

Roll period: 13.5 seconds

Steadiness - As gun platform (Average = 50 %): 51 %

- Recoil effect (Restricted arc if above 1.00): 0.60

Seaboat quality (Average = 1.00): 1.03

Hull form characteristics:

Hull has a flush deck

and transom stern

Block coefficient: 0.400

Length to Beam Ratio: 10.29 : 1

'Natural speed' for length: 21.90 kts

Power going to wave formation at top speed: 64 %

Trim (Max stability = 0, Max steadiness = 100): 50

Bow angle (Positive = bow angles forward): 25.00 degrees

Stern overhang: 3.00 ft / 0.91 m

Freeboard (% = measuring location as a percentage of overall length):

- Stem: 23.00 ft / 7.01 m

- Mid (50 %): 14.00 ft / 4.27 m

- Quarterdeck (15 %): 14.00 ft / 4.27 m

- Stern: 14.00 ft / 4.27 m

- Average freeboard: 14.72 ft / 4.49 m

Ship space, strength and comments:

Space - Hull below water (magazines/engines, low = better): 155.2 %

- Above water (accommodation/working, high = better): 61.6 %

Waterplane Area: 8,049 Square feet or 748 Square metres

Displacement factor (Displacement / loading): 85 %

Structure weight / hull surface area: 37 lbs/sq ft or 179 Kg/sq metre

Hull strength (Relative):

- Cross-sectional: 0.50

- Longitudinal: 1.69

- Overall: 0.56

Hull space for machinery, storage, compartmentation is cramped

Room for accommodation and workspaces is cramped
