I found the armor diagram for the Ger/CBL/1915 Mod.A design

Since I had the cross section for the Ger/CBL/1915 design, I thought that it would be worth recalculating. One thing I learned immediately is that there is no armor protection on the anti-torpedo protection system. To save weight, there is only compartmentation. This is the new Springsharp report:

Overall survivability and seakeeping ability:
 Survivability (Non-critical penetrating hits needed to sink ship):
   23,104 lbs / 10,480 Kg = 26.7 x 12.0 " / 305 mm shells or 1.9 torpedoes
 Stability (Unstable if below 1.00): 1.27
 Metacentric height 5.5 ft / 1.7 m
 Roll period: 14.3 seconds
 Steadiness - As gun platform (Average = 50 %): 51 %
   - Recoil effect (Restricted arc if above 1.00): 0.29
 Seaboat quality  (Average = 1.00): 1.02

Hull form characteristics:
 Hull has rise forward of midbreak
 Block coefficient: 0.494
 Length to Beam Ratio: 10.00 : 1
 'Natural speed' for length: 28.28 kts
 Power going to wave formation at top speed: 60 %
 Trim (Max stability = 0, Max steadiness = 100): 50
 Bow angle (Positive = bow angles forward): 3.00 degrees
 Stern overhang: 2.00 ft / 0.61 m
 Freeboard (% = measuring location as a percentage of overall length):
    - Stem:  35.00 ft / 10.67 m
    - Forecastle (20 %): 30.00 ft / 9.14 m
    - Mid (67 %):  30.00 ft / 9.14 m (22.00 ft / 6.71 m aft of break)
    - Quarterdeck (15 %): 22.00 ft / 6.71 m
    - Stern:  22.00 ft / 6.71 m
    - Average freeboard: 27.76 ft / 8.46 m

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 117.1 %
  - Above water (accommodation/working, high = better): 243.8 %
 Waterplane Area: 42,425 Square feet or 3,941 Square metres
 Displacement factor (Displacement / loading): 106 %

 Hull space for machinery, storage, compartmentation is cramped
 Room for accommodation and workspaces is excellent
