Cliff's GB/BB/1912 design

My friend Cliff's design for a 1912 battleship that he intended to build in numbers ended up larger in Springsharp than he had hoped back in 1971. The design had 9-15in/42 BLR and 14-6in QF guns, with a 14in belt and 7in deck. The tanti-torpedo bulkhead was 2in. The best information that I have is a cross section that shows the armor arrangement. He only wanted 22 knots, although the design could easily have been a 26 knot ship, since the length was 700ft. I had the most problems with stability, and I don't totally understand the issues, except that perhaps I was overly generous with turret and barbette armor. I'm not absolutely sure about the ram or plow boq, but that is what I think that Cliff intended. This is the Springsharp report:
