Oh I haven't forgotten. I still need some big ships to project power.
Should your Flagship not be the one that does the projection of power for you? :)

Who fears a Channel Fleet with 12 2k warships and 1 6k warship? My flagships will probably be major station vessels, they have quarters for an admiral (or ambassador/envoy/etc) and a 50-strong marine detachment. They can be supported by whatever else is available but they pose a potent force on their own. Additionally they may be withdrawn to serve in the Channel, since they are powerful ships of the line in their own rights.

Contradiction here, I think you mean 2 twin mounts.
Don't worry, Darman. You're not the only one to make that mistake. I noticed that with a few of my unposted sims I forgot to change that as well, so I will need to check them all before I post them.

Oh boy! I'm glad I'm not the only one. I was in the middle of a fantasy football draft when I posted that ship so I was a little distracted.
I wanted to cover the entire 10ft freeboard with armor, so should I make my main belt say 8ft tall (1/2 below waterline and half above) and then my upper belt would be 6ft tall?

That's how I've been doing it.
I made her a little more seaworthy than her predecessor by about 5ft worth of freeboard. I'm considering building two of these monstrosities;
HMS Devastation and
HMS Thunderer.

No deck armor?
I was considering deck armor. How useful would you believe deck armor to be during this era?
Historically, designers considered it necessary. Why? Not because of plunging fire (that would only ever happen if a ship was close to a fort on a bluff or cliff which could actually aim downwards), but because of shell detonations driving chunks of the shell downwards into the ship (and worse, out the sides or bottom). Your belt armor is strong enough to keep out most projectiles until ranges get close (or the iron shatters), but a shell hitting your superstructure, bow, or stern could detonate and send pieces of the shell through the side or bottom of the ship.
Historically, the Devastation class had 2-3" of deck armor.
Added deck armor, and brought her up by 249 tons to 8000t light on the dot. I want people's opinions on using Coles-Ericcson turrets rather than closed barbette mounts in 1870. Which do you think is more appropriate?

Coles-Ericcsons are totally appropriate for this design and this time period, and will remain so through the 1880s. An open barbette design would also be appropriate now, they're coming into vogue historically. It's probably too early for a closed barbette design.
No ram?
It didn't appear the historical designs had ram bows. I would use these massive ships as stand-off weapons, designed to stand off and use their massive heavy guns to pound an opposing fleet as swifter vessels with rams and faster-firing guns move in.
I would think that that is a ram bow at the front there on the historical design...
(http://upload.wikimedia.org/wikipedia/commons/thumb/6/60/Devastation_class_diagrams_Brasseys_1888.jpg/693px-Devastation_class_diagrams_Brasseys_1888.jpg)
Hrm. Totally missed that. I've never understood the fascination of ramming by battleships anyways. Besides which, in my humble opinion, the best tactic would be to lay the Devastation alongside the enemy and pound her, then move off. Or just stand off and pound her. A headlong charge into an enemy fleet would allow her to be raked by the lighter, faster-firing weapons of the enemy vessels. Lets say each turret manages to kill one medium or light enemy combatant and she kills another with her ram. Then Devastation dies.
The reason for the fascination with ramming lies in 2 actions: CSS Virginia vs USS Cumberland, and the battle of Lissa. During the 1860s, the fear was that the defence (in the form of armor) was dominant over the offence, the guns simply could not penetrate the armor of heavy-weight ships. Ramming had been shown to be effective at actually SINKING the enemy. Given Devastations belt armor, lighter, faster firing weapons will be hard pressed to seriously hurt her (chew up the superstructure, yes, riddle the ends, yes, penetrate 18" iron, no). The decks are a little light, so there's a bit of vulnerability there, but other than that.....
In naval history, there were plenty of times when navies of the world was lead astray by novel ideas.
In the late 1800s, ramming was seen as the only tactic possible to sink enemy ships. Weapons of the time up to the Russo-Japanese war were only able to disable enemy ships (soft kill) and unable to sink (hard kill). Of course, like many popular trends, it was blinded to the fact that often the rammer was harmed more than the ramie. The Battle of Lissa played an important role in shaping this trend because it showed that it was possible to sink ships by deliberate ramming. For the most part, ramming was accidental in nature before that.
Some other misguided trends: Torpedo battleships and the torpedo craze, the Japanese obsession with diving shells, Fisher's obsession with higher and higher speed on ships, etc.
Now has a ram bow, slightly thicker deck armor, and has more end belt armor to help support ramming as a viable tactic. Is 7" enough or do I need more?

And for fighting river pirates.... the
Beacon-class was essentially a colonial patrol and customs vessel. I may have made it a little smaller than it originally was, she and her sisters were iron-framed and wood-hulls, so I might have had extra strength to play around with.

Now has a ram bow, slightly thicker deck armor, and has more end belt armor to help support ramming as a viable tactic. Is 7" enough or do I need more?
Ramming will be viable with 7" armor. In general, though, expect the rammer to be damaged by ramming, just not nearly as badly as the rammee (see HMS Camperdown).

Oh I know. Which is why I expect it to never use the ram. These will be the last warships with rams (I personally find them stupid.).
Rams make some sense, given the limitations of the 1860s. By the mid 1870s, they're starting to be less useful, because LARGE (like the 450mm RML) guns can overwhelm the armor of the day, and torpedoes start to become an issue.
How do my other vessels look? The Monarch especially. But the Beacon as well.
I'd somehow missed Monarch. Looks OK from here, the 7" turrets are a-historical but but should work OK. The forward rigging would also prevent a 7" turret on the foredeck from firing forward (that's why the historical ship had its forward guns in the hull).
Beacon looks OK for it's role, especially for riverine operations.

Good point. Would that be a forward facing casemate then? Or deck mount but in the hull?

The historical guns would be side-mounted casemates installed as far forward as you could get. Rather like bow chasers on a sailing ship.
okay. I'll alter the plan to reflect that

You could probably move 2 of the guns to centerline pivot mounts, to increase your broadside by 1 gun. Other than that, looks solid.

These two are intended as commerce protectors?
Rules-wise, they seem fine.
Commerce protectors and as well as potential cruisers.
Should be fine in those roles, they should avoid tangling with anything ironclad, but that's a good rule for any unarmored ship at this time (and sometimes, like SMS Kaiser at Lissa, you can come out well even if you're unarmored and up against armored foes).

I'm looking at building 5 lightly armored corvettes as well. Not as fast though, but they will provide convoy protection when needed.
So, this is intended to be a civilian vessel that during wartime may or may not be outfitted to act as a Letter of Marque vessel. This vessel is distinct from a privateer in that it is a fast merchant ship during peacetime and during wartime it continues to be a fast merchant ship with a caveat: its owners may decide to apply for a letter of marque allowing this vessel to carry guns to defend itself from enemy raiders so it may fight its way free of a blockade or through a blockade, and also snap up any unarmed enemy vessels it may run across. As such it is lightly armed, and it is primarily a merchant vessel (and paid for in cash, not BP, except the armament, which may be added after a 2 month refit at the coast to add armament).

You know I didn't even think to check that... so now I need to add engines and put in her top speed :p
Heh, that's one reason when I did my cargo barque that I fitted her with a short-legged engine. ;) Of course, now that we've updated the sailing rules, I'll have to update her speed to keep it working. Oh, well, price of progress.

The only real question I'd have is on the hull form: any reason for the short, wide shape?

I'm still kind of experimenting with how short the boat can be and how wide/deep it has to be so it won't tip over under sail.
I've also been looking at it from an economy perspective: an effective and cheap commerce raider I can build swiftly and flood the seas with during any war.

It's certainly cheap, and 6 guns (4 on a broadside) will probably be enough to overawe many merchants and give you a reasonable chance against the difficult ones. It's fast enough to catch most merchants, but (and this is a consequence of the low cost) not really fast enough to get away from most warships.
Made her a little more expensive (could build two of this version against three of the older version) but she's got a top speed of 13kts. Ought to be able to keep her distance, at least til nightfall.

How long can she run at full speed? 13 knots is probably a good enough speed, as long as she doesn't encounter a threat up close (in fog or bad weather), in the early morning, or a particularly fast threat.

265nm at 13 knots, thats about 20 hours steaming.

Stability's WAY too low for my blood. Also, I'd recommend fitting a few guns just in case a small raider catches her: I'd hate to surrender a regiment to a 400-ton privateer. Some Armstrong 40-pounders, for instance (http://en.wikipedia.org/wiki/RBL_40_pounder_Armstrong_gun), would be a good option, or older 68-pounders that no longer have homes.
Good point. 3 40pdrs on each broadside should be sufficient.

Block coefficient is very high, and l:b pretty low.
Broadside guns are on the main deck? I'd be a bit concerned about the 12" guns firing over them myself.

I was considering that myself right after I posted it. I did place them mid-ship, whereas the turrets are further fore and aft, I don't know if that would make all that much of a difference or not though.

It would certainly help during broadside actions, it's when the turrets are firing towards the bow or stern that it will be an issue.

did you mean the reverse?

What I meant was: having the secondary battery centered while the turrets are on the ends will help as long as the turrets are firing to the broadside (there would be some blast, but probably not so much as to be a problem). It's when the aft turret is trying to fire at a target that's forward of dead abeam or when the fore turret is trying to fire at targets aft of dead abeam where the real problems will occur.

okay I understand now. Forgive me, my mind is slightly more addled than usual due to a cold and all the tea I've been drinking (peppermint tea helps but if I drink a lot it makes me a little loopy)
Now... question for you Kworld, but do you think it would be period-appropriate for me to make the freeboard amidships higher than the foredeck and quarterdeck? That would allow me to place the broadside guns below the freeboard deck in a covered position where they theoretically won't be blown overboard by the main guns firing.

Period-wise. it would be a bit unusual, but I don't know of any reason it wouldn't be possible. SS3, however, might resist, since it puts the turrets atop the main deck. Unless you turrets below-decks.....
