Mexican Battleship?

[Desertfox]

Woops, those should be twin turrets.

Fixed a few problems. She only has enough fuel for four days of sailing, so accommodations should not be an issue.

   Miscellaneous weights: 40 tons, 1.1 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     2,977 lbs / 1,350 Kg = 8.5 x 10.0 " / 254 mm shells or 1.0 torpedoes
   Stability (Unstable if below 1.00): 1.16
   Metacentric height 2.4 ft / 0.7 m
   Roll period: 13.8 seconds
   Steadiness   - As gun platform (Average = 50 %): 51 %
         - Recoil effect (Restricted arc if above 1.00): 0.19
   Seaboat quality  (Average = 1.00): 0.80

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.600
   Length to Beam Ratio: 5.29 : 1
   'Natural speed' for length: 16.43 kts
   Power going to wave formation at top speed: 32 %
   Trim (Max stability = 0, Max steadiness = 100): 63
   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:      5.00 ft / 1.52 m
      - Forecastle (20 %):   5.00 ft / 1.52 m
      - Mid (40 %):      5.00 ft / 1.52 m
      - Quarterdeck (15 %):   5.00 ft / 1.52 m
      - Stern:      5.00 ft / 1.52 m
      - Average freeboard:   5.00 ft / 1.52 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 65.1 %
      - Above water (accommodation/working, high = better): 40.6 %
   Waterplane Area: 10,071 Square feet or 936 Square metres
   Displacement factor (Displacement / loading): 111 %
   Structure weight / hull surface area: 120 lbs/sq ft or 587 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.98
      - Longitudinal: 1.26
      - Overall: 1.00
   Hull space for machinery, storage, compartmentation is excellent
   Room for accommodation and workspaces is extremely poor
   Poor seaboat, wet and uncomfortable, reduced performance in heavy weather

She only has enough fuel for four days of sailing, so accommodations should not be an issue.

If the sailors don't like it, then they should not have joined the Navy. ;D

[Desertfox]

Plus these are Mexican sailors, they require less space than others.  ;) :P

[TexanCowboy]

Does this mean they bring their families, kids, and everyone they know along too, so that when a ship sinks, over 5,000,000 die? :P

[Walter]

No doubt some will be sleeping inside the barrels of the bigger caliber guns, too. Might be a bit problematic when they try to load those guns. :D

[Desertfox]

Tex, wrong country, you are thinking Cuban...

Definitely a problem, its going to create an artificial cap on gun sizes, as it detrimentally impacts the aerodynamic characteristics of the shells in flight...

It is if nothing else as argument for using breech-loaders, as it can get problematic if you ram home the shell and shot on top of a lot of people in a muzzle loader... ;)

[TexanCowboy]

Will the Mexicans in the gunbarrels be eating pickles? :P

[Walter]

They'll be drinking Tequilla. Then the Mexican ships will be firing incendiary shells Mexicans. ;D
