My (lame) attempt at a 1912 British Light Cruiser

This is my British Light Cruiser design for 1912. It seems rather lame, but I insisted on 4in side armour with a 2in deck. The armament is the archaic layout with a gun at each end with 3 on each side for a total of 8-6in QF guns. The speed is a semi-acceptable 27 knots. That seemed to be the minimum that would be a reasonable scout for the battlefleet. Of course, if the battlefleet consists of 27 knot ships, perhaps 27 knots is insufficient! In any case, this class is really intended for use in distant waters with cruiser squadrons. This is the Springsharp report:
