Yet another fast German batlecruiser design study

This is the Ger/CB/1916 design study for a fast battlecruiser with 6-18in (triple turrets)and 16-5in guns. I wanted a ridiculous 45 knots, but only 35 knots is achievable, by inflating displacement and adjusting freeboard, beam, and draft. The ship is flush-decked, with a tripod foremast with a top, and a tripod mainmast with a derrick. There are two tall funnels. The ship has a flared bow, a high freeboard, and a conventional stern.
