Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
16,395 lbs / 7,437 Kg = 100.3 x 6.9 " / 175 mm shells or 1.9 torpedoes
Stability (Unstable if below 1.00): 1.10
Metacentric height 2.9 ft / 0.9 m
Roll period: 15.3 seconds
Steadiness - As gun platform (Average = 50 %): 71 %
- Recoil effect (Restricted arc if above 1.00): 0.45
Seaboat quality (Average = 1.00): 1.21
Hull form characteristics:
Hull has raised forecastle,
a normal bow and large transom stern
Block coefficient (normal/deep): 0.489 / 0.502
Length to Beam Ratio: 10.53 : 1
'Natural speed' for length: 29.15 kts
Power going to wave formation at top speed: 51 %
Trim (Max stability = 0, Max steadiness = 100): 59
Bow angle (Positive = bow angles forward): 30.00 degrees

- Average freeboard: 18.60 ft / 5.67 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 117.6%
- Above water (accommodation/working, high = better): 106.7%
Waterplane Area: 28,053 Square feet or 2,606 Square metres
Displacement factor (Displacement / loading): 120%
Structure weight / hull surface area: 105 lbs/sq ft or 514 Kg/sq metre
Hull strength (Relative):

- Longitudinal: 1.03
- Overall: 1.00
Cramped machinery, storage, compartmentation space
Adequate accommodation and workspace room
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily
Warning: Calibre too large for QF, AA or DP gun - Main Battery |
