My latest attempt at the Ger/CB/1912 design

My building program for 1912 in the Anglo-German building program game was for fast battlecruisers armored along the "all or nothing" scheme and with a very thick deck. The 6-15in guns were to be all forward in two triple, turrets with one superfiring. The secondary armament was too light: 8-6in QF guns. The side armor was only 6in while the turrets and barbettes had a maximum thickness of 10in. The freeboard forward was high, with the forecastle extending 62% of the length. That makes for a good seaboat. This is the Springsharp report:
