Logi's Design Studies

[Logi]

Like the Swiss, I'm a speed manic ;) I could speeze a bit more speed out of the design, but I decided not to as it significantly lowers performance.

[Tanthalas]

The Cruiser is very.... Swiss.

its nice but dosnt have enough guns...

Btw: Can construction begin before the engine has been developed? Where one pauses construction of the ship to wait for the technology to be completed?

[Tanthalas]

Engines go in very early in construction, so you have to have the aproprita tech to start construction.  while your 4X14" ships are faster than my 6X16" ships were they to face my 6X14" ships I feal they would be at a great disadvantage in the armor catagory (they are tinclads while my 6X14" ships are BCs or Pocket fast BBs).  Personaly I just refuse to build tinclads, and I dont personaly feal that 4X14" is suficiant in the gun catagory, perhaps consider 6X11-12" as a raider type ship

[Korpen]

Guangdong, RRC Province Class laid down 1915 (Engine 1916)

They are both too slow and over-armoured. Reduce armour a bit, and you can increase speed by 2-3 knot and equip her with 38cm guns instead.

And the fact that their belts do not protect all of their magazines are a problem...

@Tan
Look at the first design on my previous post; Its a 9x11 version running at 30 kts. That's your raider-type ship answer. THe 4x14 ship was meant to counter your 6x12 ships but apparently it works against your 6x16 ships too. As for your 6x14 ships, my 4x14 ship runs a full 4kts faster. They aren't inteneded to face off with BCs or BBs but get away quickly.

[Tanthalas]

here would be the final evolution of the 6X14" program (should I choose to stay with it) also the 6X12" ships are limited by the 20k per shaft limit (they can be a full 5 knots faster in an unlimited form)

TBH while faster the 4X14" ships would have little chioice but to run away from the heavier armor and firepower that the 6X14" ships bring to the frey.

these ships are intended to be imune to their own fire at resonable ranges, and honestly pull it off rather well, while they should be capable of outruning most ships of similar tonage.

Warning!

Main belt does not fully cover magazines and engineering spaces

*runs away*

[Borys]

I sometimes get such a warning after fiddling with a design - it often is a case of a foot or two.
Borys

[Walter]

Yes. With adjusting the design, it is something that you can easily forget about. I've learned to check the belt after all changes I make to the hull and speed...

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     25,425 lbs / 11,533 Kg = 18.5 x 14.0 " / 356 mm shells or 2.2 torpedoes
   Stability (Unstable if below 1.00): 1.16
   Metacentric height 4.7 ft / 1.4 m
   Roll period: 15.4 seconds
   Steadiness   - As gun platform (Average = 50 %): 70 %
         - Recoil effect (Restricted arc if above 1.00): 0.80
   Seaboat quality  (Average = 1.00): 1.19

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.562
   Length to Beam Ratio: 9.00 : 1
   'Natural speed' for length: 26.85 kts
   Power going to wave formation at top speed: 51 %
   Trim (Max stability = 0, Max steadiness = 100): 59
   Bow angle (Positive = bow angles forward): 21.50 degrees
   Stern overhang: 0.00 ft / 0.00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      21.50 ft / 6.55 m
      - Forecastle (20 %):   21.50 ft / 6.55 m
      - Mid (50 %):      21.50 ft / 6.55 m
      - Quarterdeck (15 %):   21.50 ft / 6.55 m
      - Stern:      21.50 ft / 6.55 m
      - Average freeboard:   21.50 ft / 6.55 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 100.9 %
      - Above water (accommodation/working, high = better): 177.8 %
   Waterplane Area: 40,771 Square feet or 3,788 Square metres
   Displacement factor (Displacement / loading): 101 %
   Structure weight / hull surface area: 156 lbs/sq ft or 762 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.98
      - Longitudinal: 1.19
      - 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

Was fiddling around with the tonnage. I was missed 0.72 ft  :-[
