The "so-called" 29,000 ton battlecruiser has the usual issue

The 29,000 ton battlecruiser has this issue, in that the silhouette is so low, that I have been having great difficulty in raising the center of gravity. Part of the issue is that I wanted at least 36 knots speed, if not 37 knots. To do that, the displacement shot up to 34,222 tons. The original intent was to achieve 38 knots, which would take 6 engines and shafts, due to the "70,000 SHP limit". I may yet try an "alternative design" that would test what it would take to reach 38 knots. I have done all the obvious things to raise the CG, and it is still too high. I'm not prepared to modify the "basic look" of the ship. The ship was intended to carry 4-13.5in/45 guns at 38 knots on 29,000 tons. That seems way beyond reach, just as Colonel Cuniberti's "Ideal Battleship" couldn't be achieved on the 17,000 ton displacement. To stay at that size, I chose to reduce the armor, until it became a "battleship-cruiser". In this case, the basic looks of the "29,000 ton battlecruiser" was similar to a light cruiser. Given the dimensions, that creates a great difficulty with metacentric height. It also demands light cruiser-style machinery, to achieve an reasonable weight and volume on the boiler rooms and engine rooms.
