Miscellaneous weights: 450 tons, 12.7 %

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
7,261 lbs / 3,294 Kg = 90.6 x 5.4 " / 138 mm shells or 1.6 torpedoes
Stability (Unstable if below 1.00): 1.16
Metacentric height 2.3 ft / 0.7 m
Roll period: 13.8 seconds
Steadiness - As gun platform (Average = 50 %): 71 %
- Recoil effect (Restricted arc if above 1.00): 0.24
Seaboat quality (Average = 1.00): 1.36

Hull form characteristics:
Hull has a flush deck
and transom stern
Block coefficient: 0.450
Length to Beam Ratio: 8.88 : 1
'Natural speed' for length: 24.41 kts
Power going to wave formation at top speed: 52 %
Trim (Max stability = 0, Max steadiness = 100): 52
Bow angle (Positive = bow angles forward): 20.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 23.29 ft / 7.10 m
