A "straight" German battlecruiser design

My concept for a straight-forward battlecruiser design for circa 1915 was a vessel of 45,000 tons armed with 9-16.5in/45 (130 ton) and 10-6in (6 ton) guns. This were the specs:

• standard displacement: 45,000 tons
• dimensions: 850ft x 110ft x 30.3ft
• hull depth: 48 ft
• Cp: 0.57
• Cm: 0.97
• armament: 9-16.5in/45 and 10-6in/50
• power: 200,000 SHP
• speed: 33 knots
• machinery weight basis: 30 SHP/ton of plant
• hull weight: 15,250 tons
• hull weight factor c: 0.34 x 10^-2
• armament: 2,830 tons
• protection: 16,650 tons
• machinery: 6,670 tons
• miscellaneous: 3,600 tons
• fuel: 8,000 tons max.
• feed water: 900 tons

The ship had a long forecastle with a step aft, just forward of the after turret. The main armament was mounted in three triple turrets, while the secondary armament just had shields, and were mounted singly.
