Distribution of weights at normal displacement:
Armament: 21 tons, 1.6 %
Armour: 9 tons, 0.7 %
- Belts: 0 tons, 0.0 %
- Torpedo bulkhead: 0 tons, 0.0 %
- Armament: 9 tons, 0.7 %
- Armour Deck: 0 tons, 0.0 %
- Conning Tower: 0 tons, 0.0 %
Machinery: 635 tons, 49.2 %
Hull, fittings & equipment: 361 tons, 28.0 %
Fuel, ammunition & stores: 243 tons, 18.9 %
Miscellaneous weights: 20 tons, 1.6 %

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
395 lbs / 179 Kg = 7.5 x 4.7 " / 120 mm shells or 0.3 torpedoes
Stability (Unstable if below 1.00): 1.28
Metacentric height 1.3 ft / 0.4 m
Roll period: 11.1 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.21
Seaboat quality (Average = 1.00): 1.02

Hull form characteristics:
Hull has rise forward of midbreak
and transom stern
Block coefficient: 0.470
Length to Beam Ratio: 10.67 : 1
'Natural speed' for length: 20.39 kts
Power going to wave formation at top speed: 69 %
Trim (Max stability = 0, Max steadiness = 100): 69
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 24.00 ft / 7.32 m
- Forecastle (20 %): 15.00 ft / 4.57 m
- Mid (50 %): 15.00 ft / 4.57 m (12.00 ft / 3.66 m aft of break)
- Quarterdeck (15 %): 12.00 ft / 3.66 m
- Stern: 12.00 ft / 3.66 m
- Average freeboard: 14.22 ft / 4.33 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 173.7 %
- Above water (accommodation/working, high = better): 66.3 %
Waterplane Area: 6,472 Square feet or 601 Square metres
Displacement factor (Displacement / loading): 69 %
Structure weight / hull surface area: 28 lbs/sq ft or 134 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.49
- Longitudinal: 2.04
- Overall: 0.56
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is cramped
Ship has slow, easy roll, a good, steady gun platform

Can't really say anything negative about it, except:

Quoted

- Cross-sectional: 0.49

Cutting range by 300 miles fixes the problem.
