The GB/DD/1906 depends on lighter machinery

I was able to make the less detailed design for the GB/DD/1906 destroyer work by having lighter machinery. This was the ship that my friend Cliff planned to produce in numbers for his fleet in our game. The ship would have 2-88mm (20pdr) guns and 2-21in TT (in anachronistic fashion). The only length specified in what has survived was 265ft and the displacement was the low 800 tons. This is the Springsharp report:

 Bunker at max displacement = 164 tons

Complement:
 74 - 97

Cost:
 £0.091 million / $0.363 million

Distribution of weights at normal displacement:
 Armament: 5 tons, 0.6 %
 Machinery: 445 tons, 55.6 %
 Hull, fittings & equipment: 240 tons, 30.0 %
 Fuel, ammunition & stores: 110 tons, 13.8 %
 Miscellaneous weights: 0 tons, 0.0 %

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   216 lbs / 98 Kg = 10.4 x 3.5 " / 88 mm shells or 0.2 torpedoes
 Stability (Unstable if below 1.00): 1.42
 Metacentric height 1.3 ft / 0.4 m
 Roll period: 10.0 seconds
 Steadiness - As gun platform (Average = 50 %): 54 %
   - Recoil effect (Restricted arc if above 1.00): 0.13
 Seaboat quality  (Average = 1.00): 1.08

Hull form characteristics:
 Hull has rise forward of midbreak
 Block coefficient: 0.435
 Length to Beam Ratio: 9.81 : 1
 'Natural speed' for length: 16.28 kts
 Power going to wave formation at top speed: 72 %
 Trim (Max stability = 0, Max steadiness = 100): 50
 Bow angle (Positive = bow angles forward): 2.00 degrees
 Stern overhang: 0.00 ft / 0.00 m
 Freeboard (% = measuring location as a percentage of overall length):
    - Stem:  22.00 ft / 6.71 m
    - Forecastle (20 %): 20.00 ft / 6.10 m
    - Mid (27 %):  20.00 ft / 6.10 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: 14.32 ft / 4.36 m

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 184.4 %
  - Above water (accommodation/working, high = better): 120.5 %
 Waterplane Area: 4,509 Square feet or 419 Square metres
 Displacement factor (Displacement / loading): 45 %
 Structure weight / hull surface area: 23 lbs/sq ft or 110 Kg/sq metre
 Hull strength (Relative):
  - Cross-sectional: 0.40
  - Longitudinal: 3.58
  - Overall: 0.50
 Hull space for machinery, storage, compartmentation is cramped
 Room for accommodation and workspaces is excellent
