Heres one of the designs I came up with for Alioth. Visually picture an Arrogant class carrier with an enclosed bow and more compact island structure. The main armament is devided up into 2 twin and 6 single mounts. Any improvements to be made? With SS rules how many planes would she carry?

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
18,874 lbs / 8,561 Kg = 226.9 x 5.5 " / 140 mm shells or 2.4 torpedoes

- Recoil effect (Restricted arc if above 1.00): 0.07
Seaboat quality (Average = 1.00): 1.38
Hull form characteristics:
Hull has low quarterdeck
Block coefficient: 0.552
Length to Beam Ratio: 9.55 : 1
'Natural speed' for length: 27.29 kts

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 116.6 %
- Above water (accommodation/working, high = better): 193.8 %
