Springsharp gives a glowing report to the Ger/BB/1910 design
The Ger/BB/1910 design was intended to be about a 32,000 ton vessel with 14in armor and 9-12in/50 BLR with 8-6in/50 QF guns. The designed speed was 23 knots. The Springsharp report is quite glowing, and was easy to finalize. I only had to raise the displacement to 33,350 tons normal displacement to achieve suffiicent structural strength.
