Another attempt at the Ger/DL/1915 design

Since I was rather disappointed with yesterday's design for the Ger/DL/1915, I thought that I would see if I could do better. One thing that I corrected was that the ship was to be built in 1915, while the machinery was 1950, to get the lighter weight machinery that was required. I increased the beam to 33ft and the speed could be increased to 34 knots. I did raise the freeboard by a foot to make obtaining adequate seakeeping easier. This is the revised Springsharp report:

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   407 lbs / 185 Kg = 6.5 x 5.0 " / 127 mm shells or 0.3 torpedoes
 Stability (Unstable if below 1.00): 1.21
 Metacentric height 1.3 ft / 0.4 m
 Roll period: 12.0 seconds
 Steadiness - As gun platform (Average = 50 %): 51 %
   - Recoil effect (Restricted arc if above 1.00): 0.61
 Seaboat quality  (Average = 1.00): 1.01

Hull form characteristics:
 Hull has rise forward of midbreak,
   a normal bow and a round stern
 Block coefficient (normal/deep): 0.402 / 0.415
 Length to Beam Ratio: 10.06 : 1
 'Natural speed' for length: 18.22 kts
 Power going to wave formation at top speed: 69 %
 Trim (Max stability = 0, Max steadiness = 100): 51
 Bow angle (Positive = bow angles forward): 7.00 degrees

    - Quarter deck: 15.00 %,  13.00 ft / 3.96 m,  13.00 ft / 3.96 m
    - Average freeboard:  15.78 ft / 4.81 m

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 177.2 %
  - Above water (accommodation/working, high = better): 101.4 %
 Waterplane Area: 6,752 Square feet or 627 Square metres
 Displacement factor (Displacement / loading): 66 %
 Structure weight / hull surface area: 33 lbs/sq ft or 161 Kg/sq metre
