Sorry this took so long, took some fiddling to get seakeeping above 1.00. Design works quite well, in fact you have standard displacement listed @ 17,000 tons while this SS is 20 tons less than that full load. But I had to increase draft from 18-22' to 24.5' to get that seakeeping. Main belt had to be 550' to fully protect magazines and machinery (a must for me). Also no end belts but I did add a TDS (I feel a ship this size should have one). CT and main battery armor a bit thin but something has to give. Had to guess at laydown date plus range/cruising speed but again your design works quite well...

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
19,694 lbs / 8,933 Kg = 39.4 x 10.0 " / 254 mm shells or 2.9 torpedoes

- Recoil effect (Restricted arc if above 1.00): 0.47
Seaboat quality (Average = 1.00): 1.01
Hull form characteristics:
Hull has rise forward of midbreak
Block coefficient: 0.487
Length to Beam Ratio: 9.17 : 1
'Natural speed' for length: 25.69 kts
