Another shot at the Jap/CL/1933 design

I thought I would try the new trick (moving the date forward for machinery) for the 1933 Japanese light cruiser. It is very "edgy" with 9-16cm guns (6.3in) and 37 knots with a 12,000nm range. I still had to give it an unnaturally deep draft, to get sufficient hull strength and seakeeping ability.
