My 1909 German scout design
My Ger/CS/1909 design was really a large destroyer, along the lines of what the Italians were doing. The ship had a good freeboard, three stacks, and 4-5in guns with 2-21in TT. I was able to make it work in Springsharp by reducing the speed to 31 knots and bloating the displacement considerably above 2400 tons. The ship was unarmored. It is only an good seaboat, when I reduced the speed (and machinery weight), which is somewhat disappointing.
