A fast version of the Ger/CB/1905

The Ger/CB/1905 design is the classic light battlecruiser type. The design in anachronistic and looks British, but it works well. I wanted to see how much speed I could achieve with it, and the answer is that I could get 35 knots without a lot of trouble. Of course, it relies on very light machinery:
