Miscellaneous weights: 375 tons, 3.8 %
Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):

Stability (Unstable if below 1.00): 1.12
Metacentric height 2.5 ft / 0.8 m
Roll period: 14.6 seconds
Steadiness - As gun platform (Average = 50 %): 61 %
- Recoil effect (Restricted arc if above 1.00): 0.47
Seaboat quality (Average = 1.00): 1.20
Hull form characteristics:
Hull has low quarterdeck
and transom stern
Block coefficient: 0.496
Length to Beam Ratio: 11.00 : 1
'Natural speed' for length: 27.78 kts
Power going to wave formation at top speed: 56 %
Trim (Max stability = 0, Max steadiness = 100): 51
Bow angle (Positive = bow angles forward): 26.00 degrees
Stern overhang: 3.28 ft / 1.00 m
Freeboard (% = measuring location as a percentage of overall length):
- Stem: 26.25 ft / 8.00 m
- Forecastle (30 %): 21.98 ft / 6.70 m
- Mid (50 %): 21.98 ft / 6.70 m
- Quarterdeck (30 %): 13.45 ft / 4.10 m (21.98 ft / 6.70 m before break)
- Stern: 14.76 ft / 4.50 m
- Average freeboard: 20.13 ft / 6.14 m
Ship tends to be wet forward
Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 86.0 %
- Above water (accommodation/working, high = better): 167.2 %
Waterplane Area: 22,660 Square feet or 2,105 Square metres
Displacement factor (Displacement / loading): 140 %
Structure weight / hull surface area: 102 lbs/sq ft or 497 Kg/sq metre
Hull strength (Relative):
- Cross-sectional: 1.00
- Longitudinal: 1.65
- Overall: 1.05
Hull space for machinery, storage, compartmentation is adequate
Room for accommodation and workspaces is excellent
Good seaboat, rides out heavy weather easily
Notes:
148 tons for four automatic 15cm gun turrets (+37 tons each turret)
227 tons for all other miscellaneous weight including radar
No aircraft - extensive electronics and command spaces
Ships in Class:
- Araucanía (CLAA-24)
- Los Lagos (CLAA-25)
- Valparaíso (CLAA-26)
- Bío Bío (CLAA-27)
Personally I would use the midbreak for the break and set it to 70% (71 to be a bit more exact). In a sense, the way they are now in the sim, the aft turrets would be at the same height as the two forward turrets. Other than that, nice ship and nice pic.
