Habsburg GTB 1913

[Borys]

I finally made a 1000 design which I'm happy with. Copying the dimenions of the historical GTB 1913 helped :)

Grosse Torpedo Boot, for you heathens out there :)

Interesting artificat - decreasing range to 2000 @14knots brings up light displacement to 995 tonnes ...

   Main:   0,50" / 13 mm         -               -

   Range 1 000nm at 20,00 kts
   Bunker at max displacement = 208 tons

Complement:
   96 - 125

Cost:
   £0,143 million / $0,571 million

Distribution of weights at normal displacement:
   Armament: 12 tons, 1,1%
   Armour: 3 tons, 0,3%
      - Belts: 0 tons, 0,0%
      - Torpedo bulkhead: 0 tons, 0,0%

   Machinery: 621 tons, 55,4%
   Hull, fittings & equipment: 308 tons, 27,5%
   Fuel, ammunition & stores: 151 tons, 13,5%
   Miscellaneous weights: 25 tons, 2,2%
Torpedos and w/t - FC? you're kidding, right? For hand worked, hand loaded guns on a lively platform, using MkI Eyeball?

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     287 lbs / 130 Kg = 9,0 x 4,0 " / 102 mm shells or 0,2 torpedoes
   Stability (Unstable if below 1.00): 1,45
   Metacentric height 1,4 ft / 0,4 m
   Roll period: 9,9 seconds
   Steadiness   - As gun platform (Average = 50 %): 51 %
         - Recoil effect (Restricted arc if above 1.00): 0,14
   Seaboat quality  (Average = 1.00): 1,02

Hull form characteristics:
   Hull has rise forward of midbreak
   Block coefficient: 0,459
   Length to Beam Ratio: 9,96 : 1
   'Natural speed' for length: 16,50 kts
   Power going to wave formation at top speed: 71 %
   Trim (Max stability = 0, Max steadiness = 100): 50
   Bow angle (Positive = bow angles forward): 2,00 degrees
   Stern overhang: 0,00 ft / 0,00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      20,00 ft / 6,10 m
      - Forecastle (20%):   18,55 ft / 5,65 m
      - Mid (31%):      18,55 ft / 5,65 m (11,55 ft / 3,52 m aft of break)
      - Quarterdeck (15%):   11,55 ft / 3,52 m
      - Stern:      11,55 ft / 3,52 m
      - Average freeboard:   13,84 ft / 4,22 m

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 189,8%
      - Above water (accommodation/working, high = better): 120,2%
   Waterplane Area: 4 783 Square feet or 444 Square metres
   Displacement factor (Displacement / loading): 49%
   Structure weight / hull surface area: 28 lbs/sq ft or 135 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0,50
      - Longitudinal: 3,24
      - Overall: 0,60
   Hull space for machinery, storage, compartmentation is cramped
   Room for accommodation and workspaces is excellent - yeah, I REALLY belive this ...

I think 2x3 is no problems whatsoever...
One could have a few men behind the mounts holding a bunch of torpedo each for rapid reloading, god know one needs lots of hit to sink anything with 5cm torpedoes!

Yes I know is it a typo, but a classic one! ;)

[Borys]

Ahoj!
Good catch!
Of course I missed the zero ... well, fixing torpedo size from the Rapid Fire Torpedos of Ultimate Unavoidable Wet Doom brought the "Room for accommodation and workspaces" report to something beleivable ...

As we sometimes say in our gaming group "The Four Inch Rifles of Doom!"  Mainly because for whatever reason, when we roll for critical hits, the 4" guns seem to cause the most (randomly), and do far more damage on the crits than that guns will do.  Our battleships will miss with the mains and secondary batteries, but hit with the 4" quickfires....it is quite funny after six turns. (they all have equal chances to hit and score a critical...damage is the variable based on gun size and number of guns.  They must do damage to cause a critical hit however.)

GTB is German nomenclature, not Austrian. Zerstörer.

[The Rock Doctor]

Good design, Borys.  I think I'll be taking the same approach to fire control and destroyers.

[Borys]

Ahoj!
Groan - Zerstoerer is one of those words I simply can never spell correctly - like scraping and weight or strenght ...

Ug, Ug.  Me heathen! :D
