The August 31, 2001 version of the GB/CB/1910 design

I have a rather clunky looking drawing of the GB/CB/1910 design as I had recast it on August 31, 2001. Amazingly, the design works well in Springsharp. The armor basis is 9in and the secondary armament has been recast as 8-6in QF guns in casemates mounted in the superstructure. Six are mounted forward and two aft, between the gun turrets. The armament is 4-13.5in/45 BLR with 8-6in QF guns. The machinery is 1910, so it is not particularly light. I used the citadel length from my drawing. This is the Springsharp report:
