Fuel, ammunition & stores: 1,563 tons, 19.3 %
Miscellaneous weights: 70 tons, 0.9 %

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
11,470 lbs / 5,203 Kg = 111.7 x 5.9 " / 150 mm shells or 1.5 torpedoes
Stability (Unstable if below 1.00): 1.31
Metacentric height 3.3 ft / 1.0 m
Roll period: 12.7 seconds
Steadiness - As gun platform (Average = 50 %): 53 %
- Recoil effect (Restricted arc if above 1.00): 0.28
Seaboat quality (Average = 1.00): 1.06

Hull form characteristics:
Hull has a flush deck
and transom stern
Block coefficient: 0.550
Length to Beam Ratio: 10.00 : 1
'Natural speed' for length: 26.62 kts
Power going to wave formation at top speed: 59 %
Trim (Max stability = 0, Max steadiness = 100): 50
Bow angle (Positive = bow angles forward): 25.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 32.00 ft / 9.75 m
- Forecastle (20 %): 22.00 ft / 6.71 m
- Mid (50 %): 16.50 ft / 5.03 m
- Quarterdeck (20 %): 16.50 ft / 5.03 m
- Stern: 16.50 ft / 5.03 m
- Average freeboard: 19.23 ft / 5.86 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 96.5 %
- Above water (accommodation/working, high = better): 127.6 %
Waterplane Area: 21,979 Square feet or 2,042 Square metres
Displacement factor (Displacement / loading): 126 %
Structure weight / hull surface area: 88 lbs/sq ft or 432 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.97
- Longitudinal: 1.34
- Overall: 1.00
Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is excellent

What is the 1" end belt meant to achieve?

To be honest, I'm not sure how effective it would be either

Bullet proof to protect the crew against boarders?
