Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     2.222 lbs / 1.008 Kg = 26,5 x 5,5 " / 140 mm shells or 0,8 torpedoes
   Stability (Unstable if below 1.00): 1,17
   Metacentric height 1,2 ft / 0,4 m
   Roll period: 12,3 seconds
   Steadiness   - As gun platform (Average = 50 %): 100 %
         - Recoil effect (Restricted arc if above 1.00): 0,32
   Seaboat quality  (Average = 1.00): 2,00

Hull form characteristics:
   Hull has rise forward of midbreak
   Block coefficient: 0,380
   Length to Beam Ratio: 10,00 : 1
   'Natural speed' for length: 18,02 kts
   Power going to wave formation at top speed: 41 %
   Trim (Max stability = 0, Max steadiness = 100): 54
   Bow angle (Positive = bow angles forward): -5,00 degrees
   Stern overhang: 1,00 ft / 0,30 m
   Freeboard (% = measuring location as a percentage of overall length):

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 92,8%
      - Above water (accommodation/working, high = better): 155,3%
   Waterplane Area: 6.432 Square feet or 598 Square metres
   Displacement factor (Displacement / loading): 154%
   Structure weight / hull surface area: 47 lbs/sq ft or 227 Kg/sq metre

   Ship has slow, easy roll, a good, steady gun platform
   Excellent seaboat, comfortable, can fire her guns in the heaviest weather

Refit 1916

All oil firing, for ease of replenishment on sea and a 2 kts higher cruise speed. The 6000nm range keept the same.

The 4 18" fixed tubes are removed and replaced by or mineracks; minesweeper gear or depth change racks.


10 tons small marconi
50 tons AS or mine warfare tools.
