I can make the Ger/CB/1905 design study C2 work

By increasing the displacement, my flush-decked battlecruiser could make 27 knots. I increased the freeboard, and then the displacement. It really is large for the length and beam: 28,205 tons normal displacement. A nasty feature of Springsharp is that some parameters can disappear, if you change some other parameter, and sometimes, I'm afraid, I neglect to specify the number of rounds per gun in the main armament. I hope I have all that this time.
