The fast light cruiser Ger/CL/1914

I have the updated drawing I did in September 2001 for the Ger/CL/1914 design. The look is very German. There is a superfiring gun aft at the forecastle deck height. The armament is 9-5in QF guns. I used dimensions of 430ft x 40ft x 16ft, with a 3,500 ton displacement. The protection consists of a 2in deck and a 4in CT. This combination helped Springsharp do well, as it treated the design as a fast,light combatant:

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 174.0 %
  - Above water (accommodation/working, high = better): 143.7 %
