Speaking of too many guns in small ships. My frigates are simply overgunned. 3x4.7" and 4x3" in 900 tons. Thats the result of stuffing a post WWII Fletcher rebuilt into 900 tons. If its not a problem Ill change them to smething more realistic.

Fuel, ammunition & stores: 389 tons, 31.2 %
Miscellaneous weights: 20 tons, 1.6 %
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
2,005 lbs / 910 Kg = 38.6 x 4.7 " / 119 mm shells or 0.7 torpedoes
Stability (Unstable if below 1.00): 1.40
Metacentric height 1.6 ft / 0.5 m
Roll period: 10.6 seconds
Steadiness - As gun platform (Average = 50 %): 70 %
- Recoil effect (Restricted arc if above 1.00): 0.22
Seaboat quality (Average = 1.00): 1.35
Hull form characteristics:
Hull has a flush deck
Block coefficient: 0.470
Length to Beam Ratio: 9.06 : 1
'Natural speed' for length: 17.03 kts
Power going to wave formation at top speed: 58 %
Trim (Max stability = 0, Max steadiness = 100): 52
Bow angle (Positive = bow angles forward): 0.00 degrees
Stern overhang: 0.00 ft / 0.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 15.00 ft / 4.57 m
- Forecastle (20 %): 12.00 ft / 3.66 m
- Mid (50 %): 12.00 ft / 3.66 m
- Quarterdeck (15 %): 12.00 ft / 3.66 m
- Stern: 12.00 ft / 3.66 m
- Average freeboard: 12.24 ft / 3.73 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 97.5 %
- Above water (accommodation/working, high = better): 132.3 %
Waterplane Area: 6,020 Square feet or 559 Square metres
Displacement factor (Displacement / loading): 147 %
Structure weight / hull surface area: 48 lbs/sq ft or 233 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 0.91
- Longitudinal: 2.33
- Overall: 1.00
Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily
