I had to accept less speed for my fast German light cruiser Ger/CL/1921
I just tried the Ger/CL/1921 very fast light cruiser. I had to accept a speed of 35 knots, but for that I got a good ship. The design has always been almost unprotected. There are just a few patched os 1/2in or 1in armor. The ship is trying to be like an Italian light cruiser from the 1920's or early 1930's, and is like a large destroyer, but better armed and with more seakeeping ability. I am started to insist on good seakeeping ability in what I do, despite the cost.
