New Confederate Ships 1910/1911

It doesn't list the individual weight, but says the whole ship is 10,000 tons.

[The Rock Doctor]

I'd contemplated "Kearsarging" one of my older PDs or ACs as it was retired, but couldn't find any info on the weight of the crane itself.  The 4:1 weight to capacity ratio's probably a safer bet.

A Wikipedia item on "crane (machine)"...

http://en.wikipedia.org/wiki/Crane_%28machine%29

...links stability with crane performance - so the Ingals ought to be pretty good there.

Nice design - I'm sure it will come in handy.

[Carthaginian]

Thanks, Rock.
I've been working on her for about 3 weeks now, but the idea has been around a LOT longer. I was going to use Nevada and Mississippi for this task, but they served better being sold to the DKB. Ingals herself started out as a semi-joke... "can I build a ship that was capable of building a ship?" I decided that a 250 ton TB would be a reasonable goal, and I ran with it. She basically carries enough materials to build 4 of them, if you'll notice. ;)

Anyway, she's likely to deploy anywhere my fleets do to serve as a destroyer flotilla tender and major repair ship, being able to re-gun or re-armor a battleship if need be and materials available.

[The Rock Doctor]

Just don't design a ship that can build a ship that can build a ship.  Therein lies madness.

[The Rock Doctor]

Oh, forgot - nice work on the pic.  She is gloriously homely.

[Carthaginian]

After long debate as to what course the next class of patrol vessels for the Gulf of Texas should take, the Confederate Navy split the difference between a well-armed destroyer and a small cruiser. Carrying six 20" torpedoes- new models with extended range- and mounting four 50-pounder QF guns, the F-01 class is affordable, fast, and one of the most powerful 'destroyer' type vessels in the world today. With a top speed of over 29 knots and a cruiser range of over 1200 n. mi @ 20 knots, they are also some of fastest and most long-ranged destroyers afloat. They are also the first class of vessel that the CSA will launch with advanced fire direction equipment built into the design.

5 will be laid down in 1/1911, with a further 5 planned for laydown each half for 2 years. The initial run is expected to enter service by Christmas 1911.

NOTE: Tall sailors find this ship rather unattractive, as the deck height of more than half the upper deck is only 7'... causing a lot of bruised heads in rough seas. Generally, shorter, stouter men are looked for to be posted on these ships, but the occasional tall man winds up aboard.

[Sachmle]

BC's a little on the low side at 0.419, but a nice ship nonetheless.

[Carthaginian]

BC's a little on the low side at 0.419, but a nice ship nonetheless.

Well, she's meant to be thin, thin, thin and fast, fast, fast!
Think a Cigarette boat on steroids, with enough firepower to make anyone who is ABLE catch it think twice about WANTING to do so. These aren't so much a destroyer design as they are a replacement for the myriads of old 2000 ton cruisers I have floating around.

[Ithekro]

Thin, yes.  I little too thin, maybe.  Rule of thumb is .043 is as low as one should go with a destroyer.

[The Rock Doctor]

It is?  Every can I've built has a BC of 0.40.  I thought the CSA DD was thinner than I'd want (though legal), but I thought his BC was fine.

[Tanthalas]

I view .40 as the limit on DDs to its what I shoot for

[Carthaginian]

Thin, yes.  I little too thin, maybe.  Rule of thumb is .043 is as low as one should go with a destroyer.

0.40 is the limit I was informed of.
Nothing below 0.40.

Nothing hard and fast about anything eles in the rules, so the design is legal.

1 - Destroyers have a minimal overall and cross-sectional strength of 0.50 - this is to represent lightweight destroyer machinery, as realistic speeds cannot be met with keeping composite strength to 1.00.  For ships of composite strength below 1.00, we as mods reserve the right to deal out damage or even loss in heavy weather.

2 Hoists
Light/protected cruisers should have hoists with the gun mounts if the appropriate technology was researched. Destroyers of WWI had no hoists for individual guns.
A cruiser without hoists have lower sustained RoF, and is more vulnerable due to the ammo exposed on the deck.

3 - Upgrades
During rebuild, the type of the machinery and the number of shafts cannot be changed. If it was reciprocating engine, you can exchange it for another one, but not diesel or steam turbine. Coal-firing boilers can be upgraded to oil-firing ones, though.
It is. howeverm possible during reconstruction, although there is a good chance that the resulting ship will have very bad vibrations and problems associated with the drastic structural changes.

4 - Submarines
Submarine designs should be based on historical ones, due to unavailability of any reasonable sub building simulators. Cost is the surface displacement in BP, and twice the BP price in $.
E.g. a Submarine with 300t surface displacement (e.g. U-1) cost 0.3BP and $6 to build, taking 6 months.
A larger cruiser submarine of 2000t displacement cost 2BP, $4 and takes 11 months to finish.

5 - Superfiring turrets on Battleships

Advanced BB Architecture allows 'superfiring' turrets like in early RN or German dreadnoughts. This superfiring is, however, only for the purpose of reducing the length of the armroed citadel. X turrets cannot have end-on-fire superfiring Y, as the sighting hoods of Y are not fully closed. They can fire to the sides, though.
All-centreline turrets still require the next BB tech.

6 - Mines
A ship must have 1 ton misc. weight for each carried mine;

7 - Torpedos
Torpedos must must have misc. weight assigned to them as per Torpedo Tech table, both for Torpedoes ready to launch and those for reloads. Capital ships generally carried around 20 (16-24) torpedoes. Adjust misc. weight accordingly and note the number of torpedoes on the SpringSharp report and how much of that is are the torpedoes.

8 - Number of Shafts
It is considered impractical to install more than four shafts per ship, so no more than four shafts per ship.

9 - Marconi
A radio with 250-400 (2000 at night) mile range weights needs 25 tons misc weight assigned to it.  A 100 mile range set requeries 10 tons.

10 - Transom Stern;
Not allowed.

11 - Drydocks
Overal ship lenght is considered.

12 - Fire Control system
FC requeries Miscelenous Weight
Battleships (+15K) - 250 tonnes
Cruisers - 100 tonnes
Destroyers - (-2K) 25 tonnes

[Ithekro]

I must be thinking about something else than.

[Carthaginian]

Finally convinced of the need for a battleship that is fir for more than simple coastal defense work, the CSA has finished plans for a more powerful battleship to be built between 1910 and 1913. It will be the CSA's first true Arcadia-type battleship. Carrying 4 twin 13.5" turrets and armed with new 1500-pound shells, the Oklahoma and her sisters are designed to be powerful and economical. Displacing only 1500 tons more than then Nuevo Leon class light, the Oklahoma has 1/3 more firepower. Three units are planned for laydown in 1910 and 1911.

Oklahoma, Confederate States of America Battleship laid down 1910 (Engine 1909)
   - Torpedo Bulkhead:
      1.00" / 25 mm   350.00 ft / 106.68 m   28.00 ft / 8.53 m

I think that the bulkhead need to be thicker, such a thin bulkhead is likely to fail most of the time the ship is hit. Just one more cm should be enough.  As the ship is otherwise very well protected this weakness really stands out.
