I actually have a pretty well-protected, large, fast battlecruiser design

I have this design for a very fast German battlecruiser that I must have done about 1973. The ship hsa 6-16.5in guns, in two triple turrets, forward, and 20-5in guns in twin mounts. The armor basis is actually 11in and the speed is 37 knots. The size ballooned, of course, although I knew way back that this was a large ship (I guessed 47,550 tons, standard displacement). Springsharp's only gripe is that the spaces below the waterline are cramped, although I would say, not excessively so.
