The original Ger/CS/1905 concept
The original Ger/CS/1905 scout cruiser was conceived as a 1905 German version of the "Super Swift" design study. Of course, the "Super Swift" was a British 1912 design study for an alternative design for the 1912 light cruisers. By using the lightest possible machinery, a successful 36-knot Ger/CS/1905 is possible. The draft is 13ft and the freeboard aft is a rather high 14 feet. This is my concept of what a Ger/CS/1905 scout would like like:
