PIC UPDATED BELOW

The John Lowe (Dispatch Vessel, Torpedo), in finished form.
The rope ladder didn't fit the more 'modern' vessel- I might amend the South Carolina to feature one, though. I plunked down about a dozen small ventilators, added an anchor capstan and some mooring cleats. I also attempted to 'dress up' the funnel a bit though I'm still not completely happy with the result. Any other last-minute things that I might have missed, or which could be improved upon?

Flags are (stem to stern) Naval Jack, National Flag, Commission Pennant, Ensign.

How do you get up to the conning platform?
There's usually a small pipe on the front of the funnel though the name escapes me.

Crap... forgot the ladder to the bridge.
Pipe in front of the stack for the steam whistle?

Will get right on those two. Tennessee will be the next to get the detailed treatment.

Aiming for a more 'manageable' and 'economical' design for an initial battleship for the Confederate Navy, I have taken "Ye Olde Choppin' Axe" to the Tennessee and this is the result- the Georgia. Overall displacement is reduced by about 3,300 tons across all load states, making the vessel more on par with the OTL U.S.S. Maine and U.S.S. Texas of the same period.

Protection is roughly equivalent to both these vessels along the waterline (10" belt, 188' L x 8' H); however the Georgia lacks the large amount of unprotected hull that plagues both these designs, adding a 5" upper belt and a 5" end belt to complete the waterline coverage. The 12.75"/L35 gun barbettes are 10" thick and the 6.4"/L35 casemates are protected by 5" armored boxes locally.

The vessel is armed with two 12.75" guns, eight 6.4" guns and eight 2.25" guns. The 12.75" guns fire a 1000 pound shell, and 60 rounds are carried for both main guns. Sited in open barbettes (which function well enough in the mild, sub-tropical weather), these guns have all-around loading, but fixed loading elevations. The 6.4" guns fire 125 pound shells at a rate of 3 per minute (sustained), but have limited coverage of the fore and aft quarters.

Speed is slightly lower than Union navy counterparts- just under 16 knots. Their 4300 n. mi. range (@ 10 knots) is judged sufficient for defending the Confederate coast. Unlike most Confederate vessels, they lack torpedo carriages; the deck was simply too crowded to add them. They are (in comparison to figures on some of the ships of the time) very seaworthy and should be rather easy ships to fight.

I highly doubt the South would ever have agreed to that - the only way they would have given up slavery was by force of arms. Unless you interpret "at Her Majesty's insistence" to include a British invasion of the CSA.

Without UK intervention the CSA won't survive the war, so there's no need for a British invasion.
Besides, slavery was beginning to become uneconomical and would probably have been largely gone by that time anyway.

That is quite badly incorrect, sir. The balance of the South's economy was not held in terms of bankable capital, but in physical property such as land and slaves, both of which were necessary to produce cotton and tobacco. If the South had a skills-based manufacturing oriented economy to protect, then your argument would indeed be accurate; but the effect of possessing such cheap labor resulted in the South adopting an economic model centered around labor-intensive agriculture. In point of fact, so long as the South counted part of its wealth in slaves, it ALWAYS had a vested interest in maintaining the value of their cheap labour. You cannot argue that slavery would magically 'become uneconomical" when I can cite the exact same "economic arguments" for slavery repeated in the modern day - albeit in regard to illegal Mexican labourers.

The system created in the South and perpetuated in the CSA made nice sounds about freedom and rights - some of which I agree with in the abstract - but the bottom line is that the South was a deeply corrupted system upheld and defended by fanatics, and needed to be violently purged of its errors. It's a good thing that the North was both willing and capable to pay the price to do so.

I agree with Brock on this. Writing a study of one of South's greatest generals, Joseph E. Johnston, I've come across the slavery dilemma enough times to realize that it was the mainstay of the South's tottering economy. Albeit Jefferson Davis could hardly be labelled a fanatic, he, too, staunchly defended that institution. That real fanatics, such as John C. Beckinridge, Alexander Stephens, Robert Toombs etc did so, is less surprising. Even the grat, iconized "Marse" Robert Lee did, in fact, defend it, not manumitting his slaves (though only a handful) till 1863, i e after the Emancipation Proclamation. Johnston, on the other hand represented the future side of the South, the entrepreneurial class, that came to lift states such as Virginia and Georgia to industrial strengh.Typically, he and his family did not own slaves nd his own views on slavery was negative, if not neutral. He championed black soldiers and regiments, and strove to better the conditions for the slave labor employed by the Army of Tennessee during the 1863-64 campaign, which culminated in his removal and the appointment of the rabid John Bell Hood, and the loss of Atlanta. So, South did have people who could see the writing on the wall; alas they were often ignored or badly misused.
One note on this: while the legendary story about Lee's post-war encounter with freedmen is a fable, told to hide or sooth over Lee's racism, Johnston had no problems working together with the first black congressmen, elected under the Reconstruction, when he sat in the U.S. House.

:rolls eyes:
As to the political end of the discussion, this is my only comment- if you don't like it, you don't have to visit this thread anymore... but please don't clutter my pictures with politics. PM me if you want to talk my ear off over a debate that has been ongoing for 150 years now.
Quote:
Toranaga: “The Netherlands were vassals of the Spanish king until just a few years ago. Is that true?”

Blackthorne: “Yes.”

Toranaga: “Therefore, the Netherlands – your allies – are in a state of rebellion against their lawful king?”

Blackthorne: “They’re fighting against the Spaniard, yes, but – “

Toranaga: “Isn’t that rebellion? Yes or no?”

Blackthorne: “Yes. But there are mitigating circumstances. Serious miti- “

Toranaga: “There are no ‘mitigating circumstances’ when it comes to rebellion against a sovereign lord!”

Blackthorne: “Unless you win.”

Toranaga: “Yes, Mister Foreigner…you have named the one mitigating factor.”
The South failed to meet the 'mitigating circumstance'- they did not win.
As they did not win, they did not have the opportunity to expand their industrial sector (which was forced to grow exponentially by the necessities of war). They did not have the reason to develop newer methods of farming- mechanically assisted farming was in it's infancy in the mid-1800's, but would sprout wings and fly later in the century and mature into a full-blown science by the beginning of the 1900's

As for the economics:
Slavery was indeed going to become economically unsustainable, gentlemen- whether it was 'central' or not.
A man with a single steam-powered tractor could out plow a dozen slaves with mules... so why pay for the slaves? They are hideously expensive: purchase cost, housing, food, treatment of various ills, etc. If any of you come back with madness about slaves simply being worked to death, expect to be ignored, as that simply wasn't true by this time. Also, floods of immigrant workers were beginning to make slaves ore expensive than hired men- why buy a slave for a hard/dangerous job when you can rent an Irishman for a dime a day and an extra dime if he dies (going rate at the cotton slide in Perdue Hill, AL, where the one William Travis once practiced law)?
A healthy, adult slave could cost $1000 or more by the 1860's (I've seen BOS for several in the $900 range in our old county archives). This is what- $50k+ in our money? Now, the Irishman costs $36.50 a year- $912.00 for a 25 year working life. That is ALL the Irishman costs- the slave is not including 'maintenance' costs like food, housing, clothing, medical treatment, and so forth. No doubt, like all 'employers,' some skimped here... but going by a normal bell curve (or even a natural desire for greatest efficiency in an enterprise) most did not- poorly maintained employees are poor workers, and do not return on their investment. As an average slave only gave about an 8-10% return.... well, not a lot of margin for error there to make money. Most plantations would, by the 1880's, be looking into steam-powered machines for the hardest work and be able to rent the remaining manpower needed at planting/harvest time.

A slave in 1861 = $900
A steam tractor in 1907 = $1150 (9 hp)

http://www.smokstak.com/forum/showthrea ... light=cost

The slave can plow one row- but you have to buy the mule, plow, traces & harnesses, etc... not to mention food for all involved.
The tractors could work a lot cheaper... combustible materials are very cheap in the south- and some tractors burned HAY, which is an almost free waste product of crop rotation (which would have developed one way or the other).

Slavery might have lived on for some period time for skilled laborers- master blacksmiths, coopers, chefs, ect- but the advent of mechanical aids for farming would soon render large-scale slavery a questionable economic return. Those that dismiss these facts might be looking at 1961-1865 and I cannot fault their logic IF APPLIED TO THAT TIME PERIOD... but they are not truly looking into the future of the nation. Unskilled labor was becoming cheaper than slaves, and less risky to one's life and limb as well as a hired man has a lot more to loose during a revolt than a slave.

Now, I shudder to think how unions like the Teamsters might have effected the economy of the South by the 1920's... but that is another story entirely.
