After calibrating my program for the Queen Elizabeth class, I am now wrestling with the ship specification for my GB/CB/1905 design to try and lower the metacentric height (GM). I have had only moderate success at this, but I do have the GM at the legend displacement below 10ft (!). I must admit that the ship has a low silhouette, given that it doesn't have superfiring turrets. There are just the forward and aft 12in/45 twin turrets with 9 single 6in/50 guns in armored shields. As things stand right now, this is what I have:
Designed draft=26.0604 ft Hull Weight=10995.6 tons Secondary Battery Weight=165.6 tons (includes protection) Armament Weight= 1576.08 tons (includes protection) Total Armor Weight=4097.17 tons Machinery Weight=8428.57 tons General Equipment Weight=750.0 tons Normal Fuel Weight=750.0 tons Maximum Fuel added Weight=1875.0 tons Reserve Feedwater Weight=1075.28 tons Legend Displacement=27392.4 tons Legend Draft=28.5543 ft Submergence of 1195.69 of actual displacement per foot At Displacement=27392.4 Length=770.0 ft Beam=85.0 ft Draft=28.5543 ft Cp=0.54 Cm=0.95 Cb=0.513 At Displacement=27392.4 tons DLR=60.001 Wetted Surface=73481.9 B/H=2.97679 At speed of 30knots power is 104406.0 SHP At speed of 31knots power is 125104.0 SHP At speed of 32knots power is 147027.0 SHP At speed of 33knots power is 170186.0 SHP actual speed for 147500.0 SHP is 32.0204 Metacentric height at legend displacement (GM)=9.36508 Waterline Coeff=0.661362 Block Coefficient=0.513 Stability Coeff (nu)=0.445718 Freeboard=24.9905 Draft=31.0095 Beam=85.0 Metacentric height at deep load displacement (GM)=10.4897
