Cliff's GB/DT/1914 design

My friend Cliff invented a warship designation. It is essentially like a German torpedo boat, of the small destroyer type. It is an odd beast, as I have not seen such a low composite strength be acceptable to Springsharp:

GB/DT/1914, Great Britain Destroyer-Torpedo boat (DT) laid down 1914

Displacement:
	959 t light; 985 t standard; 1,068 t normal; 1,134 t full load

Dimensions: Length overall / water x beam x draught
	266.70 ft / 265.00 ft x 28.00 ft x 11.00 ft (normal load)
	81.29 m / 80.77 m x 8.53 m  x 3.35 m

Armament:
      1 - 4.00" / 102 mm guns in single mounts, 32.00lbs / 14.51kg shells, 1914 Model
	  Quick firing gun in deck mount 
	  on centreline forward, 1 raised gun
	Weight of broadside 32 lbs / 15 kg
	Shells per gun, main battery: 250
	9 - 21.0" / 533.4 mm above water torpedoes

Machinery:
	Oil fired boilers, steam turbines, 
	Geared drive, 2 shafts, 27,304 shp / 20,369 Kw = 31.00 kts
	Range 1,650nm at 15.00 kts
	Bunker at max displacement = 149 tons

Complement:
	93 - 121

Cost:
	£0.156 million / $0.623 million

Distribution of weights at normal displacement:
	Armament: 4 tons, 0.4 %
	Machinery: 610 tons, 57.1 %
	Hull, fittings & equipment: 346 tons, 32.4 %
	Fuel, ammunition & stores: 109 tons, 10.2 %
	Miscellaneous weights: 0 tons, 0.0 %

Overall survivability and seakeeping ability:
	Survivability (Non-critical penetrating hits needed to sink ship):
	  290 lbs / 132 Kg = 9.1 x 4.0 " / 102 mm shells or 0.2 torpedoes
	Stability (Unstable if below 1.00): 1.07
	Metacentric height 0.8 ft / 0.3 m
	Roll period: 12.8 seconds
	Steadiness	- As gun platform (Average = 50 %): 62 %
			- Recoil effect (Restricted arc if above 1.00): 0.09
	Seaboat quality  (Average = 1.00): 1.08

Hull form characteristics:
	Hull has a flush deck
	Block coefficient: 0.458
	Length to Beam Ratio: 9.46 : 1
	'Natural speed' for length: 16.28 kts
	Power going to wave formation at top speed: 72 %
	Trim (Max stability = 0, Max steadiness = 100): 57
	Bow angle (Positive = bow angles forward): 2.00 degrees
	Stern overhang: 1.00 ft / 0.30 m
	Freeboard (% = measuring location as a percentage of overall length):
	   - Stem:		20.00 ft / 6.10 m
	   - Forecastle (20 %):	18.00 ft / 5.49 m
	   - Mid (0 %):		16.00 ft / 4.88 m
	   - Quarterdeck (15 %):	14.00 ft / 4.27 m
	   - Stern:		14.00 ft / 4.27 m
	   - Average freeboard:	15.21 ft / 4.64 m

Ship space, strength and comments:
	Space	- Hull below water (magazines/engines, low = better): 187.4 %
		- Above water (accommodation/working, high = better): 23.0 %
	Waterplane Area: 4,764 Square feet or 443 Square metres
	Displacement factor (Displacement / loading): 50 %
	Structure weight / hull surface area: 29 lbs/sq ft or 144 Kg/sq metre
	Hull strength (Relative):
		- Cross-sectional: 0.52
		- Longitudinal: 4.98
		- Overall: 0.65
	Hull space for machinery, storage, compartmentation is cramped
	Room for accommodation and workspaces is extremely poor
