Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
717 lbs / 325 Kg = 17.6 x 4.3 " / 110 mm shells or 0.4 torpedoes
Stability (Unstable if below 1.00): 1.20
Metacentric height 1.7 ft / 0.5 m
Roll period: 12.6 seconds
Steadiness - As gun platform (Average = 50 %): 71 %
- Recoil effect (Restricted arc if above 1.00): 0.39
Seaboat quality (Average = 1.00): 1.02

Hull form characteristics:
Hull has raised forecastle
and transom stern
Block coefficient: 0.400
Length to Beam Ratio: 10.42 : 1
'Natural speed' for length: 23.34 kts
Power going to wave formation at top speed: 65 %
Trim (Max stability = 0, Max steadiness = 100): 70
Bow angle (Positive = bow angles forward): 35.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 24.61 ft / 7.50 m

- Mid (50 %): 13.78 ft / 4.20 m
- Quarterdeck (15 %): 13.78 ft / 4.20 m
- Stern: 13.78 ft / 4.20 m
- Average freeboard: 16.14 ft / 4.92 m

Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 171.6 %
- Above water (accommodation/working, high = better): 103.7 %
Waterplane Area: 10,314 Square feet or 958 Square metres
Displacement factor (Displacement / loading): 79 %
Structure weight / hull surface area: 40 lbs/sq ft or 196 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.54
- Longitudinal: 1.54
- Overall: 0.60
Hull space for machinery, storage, compartmentation is cramped
Room for accommodation and workspaces is adequate
Ship has slow, easy roll, a good, steady gun platform

Given the raised forecastle, you'd probably want to sim both forward mounts as raised (so A turret can fire over the bow). Other than that, looks pretty good (other than the fact that it can't be built in a Type 1 slip, which is a common problem with ships in this size/speed range).

I don't think a 5 foot difference in the stem and fore deck at A turret really warrents the "raised guns" label for A turret, certainly for B turret though as its on a deckhouse. Raised guns to me would emply guns placed up at another deck level above the main deck.

If you consider the guns are roughly 3-4 feet above the base of the gun mount the turret only has to be raised just over 2 feet to fire dirrectly over the bow.
