Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
7 852 lbs / 3 562 Kg = 93.8 x 5.5 " / 140 mm shells or 1.7 torpedoes
Stability (Unstable if below 1.00): 1.22
Metacentric height 2.5 ft / 0.8 m
Roll period: 13.2 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.24
Seaboat quality (Average = 1.00): 1.19
Hull form characteristics:
Hull has a flush deck
and transom stern
Block coefficient: 0.444
Length to Beam Ratio: 8.95 : 1
'Natural speed' for length: 24.50 kts
Power going to wave formation at top speed: 50 %
Trim (Max stability = 0, Max steadiness = 100): 59
Bow angle (Positive = bow angles forward): 12.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 21.33 ft / 6.50 m

Slight improvements:
-- better partitioning from the bow to A turret.
-- Removal of the weakness of the structure at section 120
-- Replacing turrets on barbette by light turrets & hoists.
The weight saving can be achieved to uniform height belt on the hull and increase the thickness of the armoured deck.
-- Capacity increased rear for the stores (section 86 to 120)
-- Rail facilities for handling the MTB or mines & representation of the aft door.
-- Positioning of the catapult (option)
