Another try for the Ger/CB/1906

I found my drawing of a more refined Ger/CB/1906 drawing, done more than 30 years after the original (this was dated August 31, 2002). I thought that I should try again to see what could be done with the design. The concept was for a very fast, well-armed, but lightly armored ship. What I could do was 30 knots, at the cost of a huge increase in displacement. My new drawing is of a ship with a much higher freeboard, which is very helpful in fast ship. Springsharp says: "Ship has slow, easy roll, a good, steady gun platform. Excellent seaboat, comfortable, can fire her guns in the heaviest weather." I doubt that 33 knots is achievable, without increasing dimensions. She has become quite full, since I refused to increase dimensions (800ft x 85ft x 26ft).
