Logi's Design Studies

[Logi]

I'm not that advanced in the way of thinking so.. I fail to understand. You need experience in naval battles to think of trying to prematurely set of the enemy shells? The distance between the belts is one thing but really? I know its 1917 but thinking abo9ut it: You have a shell that has a trigger that will explode on contact, or sometime after contact. If you want to protect your ship you want it to explode as far away as possible so having a thin outer belt to detonate the shell first would work in theory. I don't see any portion of this thinking that requires naval battles. If you can make the shell you can think of this.

He have had his spies snooping around in Hamburg , snoozing the designs of the Ocean class,which is designed after the experiences of the Dutch-Siamese war. ;D 8) 8),with a fuzing plate some 5-6 feet below the main armour deck,shown after the after battle assessment on the damages inflicted on the Lbc Gujarat,after the Phuket engagement.

Per I havnt complaind about yours because I assumed you were drawing off Dutch (who are allied to you after all) Experiance (even though im not sure there were enough battles to allow for the type of info that came out OTL after Jutland).  Curently with everything any of us know 3" is suficiant deck, now I am planing to jump to 4" for my next pair of BBs but my reasoning for that will involve storyline conclusions, not just "I want to do it so I am".  Its much like the DD/TB question Guiness is researching, just because we can dosnt meen we should.

[ledeper]

We had the discussion previously when I submitted the first drafts and due to lack of English i called a "decapping"plate ,but after a fruitful discussion were Sam was very helpful,I  made clear that is was some sort of "fuzing plate as described above.   :o So it is quite possible ESC intelligence have overlooked some measly ::) :o 8) chinese spying in Hamburg ;D:(It have been stated in the open on ESC battleshipspage)

Ironclade battery could be interresting to protect BBs Battle line vs TT attack.

For this job, increase the speed to 27kts (22/24kts for the BBs)
Reduce the caliber to 6" QF

Where did you place this Ironclade in the Richmond Treaty?

NEDS...I repeat NEDS!!!!

[Logi]

It's broadside mount, 30 on each side. Its also single 6"s, which leaves more than enough space for all the rounds etc. Older ships-of-line have packed far more on far less space. The only thing that worries me really is the torpedo mounts.

If we lined up the 6"s all directly, it would only take 30 ft in total for each side.

The ammo space, if packed to the ideal would take 202.5 cubical ft. There's enough space....

[Carthaginian]

It's broadside mount, 30 on each side. Its also single 6"s, which leaves more than enough space for all the rounds etc. Older ships-of-line have packed far more on far less space.

If they were on 2 gun decks, I could see that.
A flush deck ship would be too small.

[Logi]

I had intended it to be a two-decker but I'm not quite sure how to simulate that in SS.

[Tanthalas]

Easy to simulate 2 deckers in SS just raise or lower half the guns.

I think it would be better described as lowered, since I've read several accounts of battle's of that era, (Jack Aubrey, anyone?), that describe that ships of the line could not engage with their full braodside if the surf was rough, since the ports would flood.

[Logi]

I remember something like that too, had to increase the freeboard to counteract the seakeeping drop (1.21->0.83)

      - Belts: 866 tons, 9.9 %
      - Torpedo bulkhead: 0 tons, 0.0 %
      - Armament: 59 tons, 0.7 %
      - Armour Deck: 1,062 tons, 12.1 %
      - Conning Tower: 37 tons, 0.4 %
   Machinery: 101 tons, 1.2 %
   Hull, fittings & equipment: 4,999 tons, 56.9 %
   Fuel, ammunition & stores: 790 tons, 9.0 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     13,494 lbs / 6,121 Kg = 9.8 x 14.0 " / 356 mm shells or 3.5 torpedoes
   Stability (Unstable if below 1.00): 1.26
   Metacentric height 7.6 ft / 2.3 m
   Roll period: 15.3 seconds
   Steadiness   - As gun platform (Average = 50 %): 70 %
         - Recoil effect (Restricted arc if above 1.00): 0.17
   Seaboat quality  (Average = 1.00): 0.75

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.607
   Length to Beam Ratio: 3.90 : 1
   'Natural speed' for length: 19.75 kts
   Power going to wave formation at top speed: 27 %
   Trim (Max stability = 0, Max steadiness = 100): 94
   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:      12.00 ft / 3.66 m

      - Mid (50 %):      9.00 ft / 2.74 m
      - Quarterdeck (15 %):   8.00 ft / 2.44 m
      - Stern:      8.00 ft / 2.44 m
      - Average freeboard:   8.92 ft / 2.72 m
   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 65.9 %
      - Above water (accommodation/working, high = better): 105.4 %
   Waterplane Area: 28,706 Square feet or 2,667 Square metres
   Displacement factor (Displacement / loading): 107 %
   Structure weight / hull surface area: 165 lbs/sq ft or 805 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.97
      - Longitudinal: 1.30
      - Overall: 1.00
   Hull space for machinery, storage, compartmentation is excellent
   Room for accommodation and workspaces is adequate
   Ship has slow, easy roll, a good, steady gun platform
   Poor seaboat, wet and uncomfortable, reduced performance in heavy weather
