Ah, I see the problem. This should fix it:

     Quick firing gun in deck and hoist mount, 1915 Model
     1 x Single mount on centreline, forward deck centre
      4 - 2.95" / 75.0 mm 45.0 cal guns - 12.99lbs / 5.89kg shells, 150 per gun
     Breech loading guns in deck mounts, 1915 Model
     2 x Single mounts on centreline, aft evenly spread
      1 raised mount
     2 x Single mounts on sides forward
      Weight of broadside 172 lbs / 78 kg

Armour:
   - Gun armour:   Face (max)   Other gunhouse (avg)   Barbette/hoist (max)
   Main:   0.60" / 15 mm         -         0.60" / 15 mm

Machinery:
   Oil fired boilers, steam turbines,
   Direct drive, 2 shafts, 21,689 shp / 16,180 Kw = 30.00 kts
   Range 6,000nm at 10.00 kts
   Bunker at max displacement = 201 tons

Complement:
   95 - 124

Cost:
   £0.183 million / $0.733 million

Distribution of weights at normal displacement:
   Armament: 44 tons, 4.0 %
      - Guns: 44 tons, 4.0 %
   Armour: 2 tons, 0.2 %
      - Armament: 2 tons, 0.2 %
   Machinery: 552 tons, 50.2 %
   Hull, fittings & equipment: 316 tons, 28.7 %
   Fuel, ammunition & stores: 145 tons, 13.1 %
   Miscellaneous weights: 42 tons, 3.8 %
      - On freeboard deck: 37 tons
      - Above deck: 5 tons

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     330 lbs / 150 Kg = 2.9 x 6.1 " / 155 mm shells or 0.3 torpedoes
   Stability (Unstable if below 1.00): 1.16
   Metacentric height 1.2 ft / 0.4 m
   Roll period: 12.3 seconds
   Steadiness   - As gun platform (Average = 50 %): 71 %
         - Recoil effect (Restricted arc if above 1.00): 0.39
   Seaboat quality  (Average = 1.00): 1.00

Hull form characteristics:
   Hull has rise forward of midbreak,
     a normal bow and a cruiser stern
   Block coefficient (normal/deep): 0.448 / 0.458
   Length to Beam Ratio: 9.84 : 1
   'Natural speed' for length: 17.61 kts
   Power going to wave formation at top speed: 66 %
   Trim (Max stability = 0, Max steadiness = 100): 71
   Bow angle (Positive = bow angles forward): 0.00 degrees
   Stern overhang: 0.00 ft / 0.00 m
   Freeboard (% = length of deck as a percentage of waterline length):
            Fore end,    Aft end
      - Forecastle:   15.00 %,  20.00 ft / 6.10 m,  17.00 ft / 5.18 m
      - Forward deck:   18.00 %,  17.00 ft / 5.18 m,  17.00 ft / 5.18 m
      - Aft deck:   52.00 %,  11.00 ft / 3.35 m,  11.00 ft / 3.35 m
      - Quarter deck:   15.00 %,  11.00 ft / 3.35 m,  11.00 ft / 3.35 m
      - Average freeboard:      13.16 ft / 4.01 m

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 174.5 %
      - Above water (accommodation/working, high = better): 156.4 %
   Waterplane Area: 6,219 Square feet or 578 Square metres
   Displacement factor (Displacement / loading): 60 %
   Structure weight / hull surface area: 30 lbs/sq ft or 147 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.50
      - Longitudinal: 1.68
      - Overall: 0.56
   Cramped machinery, storage, compartmentation space
   Excellent accommodation and workspace room
   Ship has slow, easy roll, a good, steady gun platform
