A fast Italian cruiser: It/CL/1942

I wanted my 1942 Italian light cruiser to be pretty fast, but to have some protection. I wanted more than the Capitani Romani class. I have 9-5.3in DP guns, 8-57mm AA guns, 12-37mm AA guns, and 8-21in TT. The speed is 37 knots. The ship can theoretically survive one torpedo hit. This is the Springsharp report:

Ship space, strength and comments:
 Space - Hull below water (magazines/engines, low = better): 181.7 %
  - Above water (accommodation/working, high = better): 196.6 %
 Waterplane Area: 21,544 Square feet or 2,001 Square metres
