First, let me say Welcome!
Second- solid ships which I'll look over in greater detail after work tonight (and which others sill take apart rivet by rivet while I am gone, no doubt), but they look rules-compliant overall.
Looking forward to seeing more... just remember, you have to start your fleet in 1895 and 1/3 of your total tonnage should come from before 1900. ;)

The last sentence is a little surprising, because I didn't notice anything like that in the rules. Conceptually, I was thinking of a nation like the US or Germany, that went from a coast-defence navy with a few long-range cruisers to a blue-water navy over the period in question. But tonnage-wise, it wouldn't have fallen out to 1/3 1895-1900, 1/3 1901-1905, and 1/3 1906-1910.
While it isn't explicitly stated in the rules, we do expect people to have something of an investment in their navies prior to 1900. The United States ballooned PRIOR to1900, not after... the same with Germany. In fact, it was 1.) the rapid growth of smaller fleets in the late 1800's and 2.) the proof of the success of long-range naval gunfire at Tsushima which lead to the British building dreadnoughts anyway.
The United States Navy's battleline quadrupled in size from two ships (Texas and Maine) in 1890 to 8 ships at sea in 1900 with two more Illinois to arrive in 1901. I can think of times that more ships were laid down and commissioned, but I can't think of any time of larger proportional growth.
Additionally, our navies are all established at this time. We are all in possession of British-sized fleets with British sized development. Our navies are not rapidly increasing, but steadily.
If this must be placed into official rules, it will be done... but I prefer to not have to rule EVERYTHING into being. If you want a large coast defense navy initially, that's fine... but no one is going to save the lion's share of their tonnage for ships that are brand new at the start of the sim.

If you have rules, they should be stated, otherwise people who don't know them will run afoul of them without meaning to.
The German navy really ballooned after 1900: in 1900, they only had 6 commissioned BBs (and calling the Kaiser Fredrich II class BBs, with their 24cm main battery, was a bit of a stretch at the time). By 1910, of course, they had 28 BBs (counting the Kaiser Fredrich's) and 1 BC.
Anyway, I was figuring to have the period 1895-1899 be one of the periodic "down" funding periods for the navy, with a turn-up starting in 1900. Doesn't mean there wouldn't be old ships, or that all the fleet dates from 1908 (far from it), but I wasn't planning an evenly-growing fleet.
There is no tonnage reserved for the torpedoes. :(
The tubes won't do a whole lot of good by themselves. ;)

So far, we have been dealing with a lot of people who have been here before.
You're the first truly new person who has applied to play. :-[
There are some things that are being discussed that haven't been codified as yet... and there will be more. Be on the lookout for that kind of thing, and point out if you notice something that is missing. Many of the people here know the intent of the rules already, some sometimes we forget to explain.
And may I extend another welcome from the egghead behind the econ rules. Please also take a look over those and see if there is anything that jumps out as wrong or confusing. I have been meaning to post an updated version, but have had a bit much on my plate from school.

Actually, there is: the tubes are listed as weighing 1.5 tons in the Armaments section, while in the Distribution of Weights section, the Weapons are listed as weighing 3 tons. 1.5 tons might seem a bit light for 3 torpedoes, but these are old, short torps, very comparable to the US "Long" Whitehead 18" (45 cm) Mark 1, which weighed 1,160 lbs. (526 kg). :)
SS3 doesn't actually allow for those weights, though... That part of the program is broken. You must manually account for the weight in the Misc Weights section yourself for the torpedoes to be included. That is stated in the rules thread... Which will be cleaned up a bit when I get some mod powerd.
Odd, since it shows them. Oh, well, no biggie.

Fast, fast, fast... not a bad vessel for this time period.
Good mine capacity. Will be a real pain for an enemy to catch.
Though... she's not really a 'coastal' minelayer; a coastal minelayer woudn't need high speed. I'd also possibly drop about 30% of the miscellaneous weight for a touch more bunker. This is especially true if you want a high-speed minelayer that would be used against enemy forces on their turf.
But turbines are a no-go on non TB/DD/CL vessels aren't they? And isn't 15cm a bit big for a mine-layer?

I think is deliberately built as a 'Light Cruiser' by tonnage and gun caliber... in order to make her able to have the turbines available only to those three vessel types.
KWorld- the loophole was left open fir a reason... to allow specifically this kind of ship to be built, because fast minelayers were built in real life. HOWEVER, remember that this ship will soak up light cruiser tonnage should they ever be limited by treaty.
She can be looked at as a cross between SMS Albatross and SMS Brummer. Brummer leaned more towards the light cruiser end of the world, being twice as large and carrying 4 15cm guns, along with 400 mines, while Albatross was earlier, slower, and only carried 88mm guns.
Under the current rules, however, she's not legal, because she's too small to be a light cruiser (minimum of 3,000 tons, which disqualifies a fair number of historical cruisers of the day), too large to be a destroyer (max of 2,000 tons), and too fast to be a gun boat (maximum of 20 knots). Actually, the rules would also disqualify the historical Albatross, on similar grounds (she was capable of up to 20.2 knots, just over the limit for a gunboat).
A rule-legal version, can be seen as an early, smaller Brummer:

Hmmm... looking at your liner, the rules MIGHT need to be adjusted a bit- might.
Let me follow that IMMEDIATELY by saying I like her; she is as realistic as the rules can make her and she isn't overdone in any way... she seems very much in line with a mid-size trans-Atlantic liner of the early 1900's.
Your ship jives nicely with the size and passenger capacity of the earlier (comparatively) Deutschland, and also in speed. The problem is that said ship had the nickname 'The Cocktail Shaker' because her massively over-sized engines caused the entire ship to vibrate at cruise speed!
A more adequate comparison might be the R.M.S. Lusitania, which- on 1/3 again the displacement- was able to carry the same bunker and relative engine power, but 411 more passengers. After all, Deutschland had her steerage passengers in dormitories while R.M.S. Lusitania gave them (crowded) 'staterooms.'
We might have to tweak the liner rules a touch- my primary concern lies in allowing too much 'passenger weight' to be placed deep in the hull. While I realize that such weight represents food, water, and other sundry necessities that don't require portholes... well, we aren't really taking those into great account in the liner figures. Well, that or we're possibly not taking the furniture, carpet, wood paneling, etc into enough account.
Might actually start a poll on this one, guys... give me a few nights (our census is still low and I might wind up with yet another unpaid day off) to run some numbers on real liners. I'll try to come up with something- either by limiting 'low weight,' increasing per-passenger weight, or adding another class of passenger.
High speed reciprocating engines ARE a problem for a smooth cruise, but the 1905 design seemed too early to switch over to turbines, given that historically the switch took place somewhat later (RMS Titanic, for instance, had both triple-expansion engines and a turbine).
A quick check says that, AT LEAST ON THIS DESIGN, changing the rules to put passengers above the waterline has no real effect:

We're talking abstract, and there isn't a ruling on things (yet)... but my argument is logical, so follow me:
Your initial design says the weights are divided as follows:
Miscellaneous weights: 11,400 tons, 47.4 %
- Hull below water: 3,400 tons
- Hull above water: 3,000 tons
- On freeboard deck: 3,000 tons
- Above deck: 2,000 tons
Your revised design has the weights divided as follows:
Miscellaneous weights: 11,400 tons, 47.4 %
- Hull below water: 300 tons
- Hull above water: 5,000 tons
- On freeboard deck: 4,100 tons
- Above deck: 2,000 tons
Not to offend, but how will you manage to cram 2000 more tons of passengers into the same space in the hull, and 1000 more tons worth of passengers into the same space on the freeboard deck level?
The answer is you cannot. You would have to allot that weight above the deck.
Now, changing the distribution of your weights has lowered the stability of the ship from 83% to 81%... yet the majority of the weight is still relatively close to the water!
If you would be so kind, please do this for me to assist in the overall study- resim the ship with the passenger weight redistributed according to these layouts:
LAYOUT #1
50% above Freeboard - representing a Liner's extensive superstructure
10% on Freeboard deck - representing the limited area of the freeboard deck
40% Hull Above Waterline - representing the large hull capacity
LAYOUT #2
30% above Freeboard - representing a Liner's extensive superstructure
10% on Freeboard deck - representing the limited area of the freeboard deck
60% Hull Above Waterline - representing the large hull capacity
Since we are trying for simple, I don't want things to get out of hand- but we can't have 80,000 ton liners trying to cram 40,000 tons of passengers into hammocks on the freeboard deck.
Thanks for your help in this and in the troop weight situation!
The how depends totally on details of design that SS doesn't force you to care about. The original design had lots of cabins below the waterline, causing coal and other supplies that might normally be there to be moved higher up in the ship. Moving the below-waterline passenger space upwards lets you put the majority of the coal bunkers down where the passenger space had been.
If you look closely at ocean liners, vs modern cruise ships, they don't have a high superstructure. RMS Titanic, for instance, looks to have 1 deck above the freeboard deck (bridge atop that), Aquitania about the same, the much later Queen Mary appears to have 2, perhaps 3 passenger decks above the freeboard deck, same with Vaterland. Take a look at this Cunard poster for Aquatania: http://en.wikipedia.org/wiki/File:Aquitaniaposter.PNG, the vast majority of the living spaces are below deck (though above the waterline).
Anyway: design to parameters #1 (NOTE: UNSTABLE!!!)

Your Sims represent the problems inherent in liner construction!
These ships have MASSIVE topweight!
They do rapidly become unstable.
R.M.S. Titanic had three decks above the main deck, and then a boat deck with additional superstructure atop these. Queen Mary has no less than 4 and possibly 5, and then the additional boat deck superstructure.
These are roughly consistent with the smaller cruiser ships- Carnival's 70,000t Fantasy class has 5 decks and possibly 6 on similar tonnage to the Queen Mary, and the Destiy has 6 decks without additional structures on the boat deck on 100,000 tons.
You must also remember that though there were a smaller number of rooms on the upper decks, they were more heavily furnished and possessed heavier fittings (Heavy = Expensive). This means that the rooms had more weight in them than might be apparent.
So, the smaller cruise ships and large liners are adequate in comparison... though even monsters like the Dream class Carnival Magic only have 6 decks above their main deck.
Might I also note that the trim on these designs has been left at 50, so adjusting that could yield some improvement to the ships handling.
I disagree: look here for Titanic's plans - http://www.titanic-plan.de/start_e.html - she has 2 decks above the main deck (the bridge doesn't count, and doesn't extend aft of her second funnel). The same is true of the SS United States (see here: http://united-states-lines.org/Big%20U%20deck%20plans.htm) - again, 2 cabin decks above the main deck (there are a few cabins on the Sports deck but not many). Don't look at modern cruise ships, they're designed totally differently from ocean liners (other than QM2, but she's so big she can get away with that pile of superstructure).

Trimming could help a bit, but stability and steadiness move in opposite directions: if you trim for stability, you lose steadiness (which if I remember correctly would be something your passengers would not thank you for).
First off, I will have to be at home to look at the pics, and I will. Second, modern cruise ships are becoming quite 'hollow,' with only a ring of cabins surrounding large open spaces two and even three decks high. The old liners were rather solidly built compared to this. I am starting to think that a 65%/10%/25% split might be about where we need things.
If anything, you're going the wrong way (if you;re thinking 65% above the waterline). Look at the picture for Aquatania I posted: most of the cabins and passenger spaces are above the waterline but below the main deck.
The designs I posted are flawed in a different way: they don't have ENOUGH freeboard. I'm thinking liners should be designed to a seaworthiness of 2.0 minimum, to get the high-sided hulls these ships had, and to give room for all the accommodations and common spaces that were below the main deck. Once that's done, if we require all 1st-3rd class accommodations be above the waterline, limit the weight on the main deck to 20-25% and weight above that to no more than double the weight on the main deck, IMO we should be good.
NO!!!!! No, no, no, no! :) I meant 65/10/25 (hull above water/main deck/above deck)! That will put it more in line with your suggestion, but still require a portion of the weight to be high up. We might also require that lifeboat weight be above the main deck as well, since they generally were.
OK, better. Requiring the boat weight to be high is fine, but it's not going to be enough to matter at 2 tons per 50 people. Also, keep in mind that while the fittings in the highest rooms are probably heavier than those in the cabins on the main deck, most period designs have a lot of promenade space on the upper decks, while the main deck accommodations stop closer (or at) the ships beam. Ie, I still think you're over-estimating the amount of weight carried in the upper superstructure, and not allowing the carriage of weight lower down where it looks to have been.
I'll try re-simming with these ideas later today.
Here's the design with 65% in the hull (above water), 15% on the freeboard deck, and 20% (plus the lifeboats) above the freeboard deck. I'm leaving the trim at 50, for better comparisons with the previous designs.

This tells me that we are getting close. Liners are not particularly 'steady' ships as they do tend to be more likely to roll over if flooded than warships. I think we're about where we need to be on these... if you run up on anything which might change the setup drastically, please let me know, but this might be it.
The following is called a BC because it's faster than normal for a battleship, it otherwise follows the sim rules (6 x 305mm, reciprocating engines, coal & oil fuel, etc). Could be considered a bigger, more heavily armored cousin of IJN Tsukuba.

She's going to be wet as the dickens aft!
Less than 10' freeboard will basically ensure that water is rolling up over the main deck in any heavy weather.
Also, the casemates are only that high off the water- meaning that unless you're in glass-smooth seas, the gunners on the 6" battery will each need a pair of swim goggles... and maybe a snorkel. They would be virtually useless in any sea state, much like the lower tier of casemates in the older British AC's. Heck, the ship's own wave action might cause them to take water!
If you have 1.01 Composite Strength, you might as well fix the fact that the end belts don't make it all the way to the ends of the hull.
You have played it REALLY close on weights- the ship has no room to improve during refits.
Just a few of the things I see ATM.
The 6 hull casemates are in the raised forward hull section, so they're a bit higher off the water than it may look (they're why there's an upper belt, it's installed to protect them). The other casemates are in the superstructure at main deck level, so they're higher, but certainly not way up in the air.
Yeah, I forgot to extend the belts the last time I played with the hull & belt length.
I'm not really expecting to add a lot of weight in refits to ships like these, they're intended to be used until they're replaced.
Ok... six 6" guns in 108' is possible; however, the way that you have the armor done, there is no hoist armor nor are there any separating bulkheads to prevent splinters or flash from going across the gun deck. This also means that the guns on deck simply have armored faces, without separating bulkheads or overhead protection. They will be, basically, deathtraps in combat.
It's always wise to leave a bit of room to grow- I made the mistake of not including any in my last nation's ships early on... and paid for it very heavily later on.
Casemates aren't nice places in combat, just like the gundeck on a man-o-war wasn't if a shot came through. However, here's a revised design....

Aside from 1.) the fact that you haven't accounted for all your torpedoes 2.) you have three guns in two single mounts and 3.) the fact that she has legs shorter than a Munchkin cat... not too bad.
If you fix those things, though, she'll be legal... and therefore better. ;)
Well, range isn't something I associate with TBs very much. However, this one is a bit better.

Ships as powerful as this one make me think about only one thing:
"God, I am terrible at designing armored cruisers."
Nice ship, far better than anything I'm playing with on a similar tonnage.
Nice AC, well balanced.
I note the survivability...low...just 3565kg for 15000t
The Defender class, fron Nova Francia is 7900t but the survivability is 4133kg.
Question:
If these 2 ships are engaged in a battle, did the survivabilities enter in the Modos calculation ?
Jef
Yes, they will. I will have to say that some simming of real life ships is necessary to solidify the process, but the survivability numbers will be very important.
All other things being equal, the survivability number has merit. HOWEVER, other things are rarely equal. If I drop my cruisers speed to 17 knots, with no other changes at all, the survivability number goes up to 9667 kg. If I then increase it's range to 25000 nm, to use up the excess strength it now has, the survivability number goes up even more, to 10,168 kg. So I'd be wary of assigning much value to it, even though it is caveated by "(Non-critical penetrating hits needed to sink ship)".

Dropping the speed increases expected subdivision- large engines require large engine rooms, meaning they are easier to flood and present proportionately more danger to survivability when flooded.
Increasing range increases subdivision as well- the fuel tanks are sealed on all sides and aren't likely to flood the interior of the ship unless it is a 'critical hit.'
That's why the survivability figure is a pretty good indicator of survivability; that's also why I'll be using it to determine how survivable our ships are.

Coal bunkers are NOT sealed, though, there are coal scuttles that have to be accessible to get the coal out of them. As noted in the NavWeaps article on Torpedo Defense Systems (http://navweaps.com/index_tech/tech-047.htm), these did not tend to survive hits in a closed state.

SpringSharp, in her less than perfect algorithms, doesn't differentiate. ;) Coal bunkers fared fairly well against
projectile hits; as you note, it was
torpedo strikes where they suffered. For shell hits, ships with coal bunkers actually preformed better than the more modern oil-fired ships.
Be
very, very aware that any ship with coal firing will have a little drawback called
Poor Subdivision in the
Victory at Sea system... which
doubles not just damage from torpedoes, but doubles the severity of flooding as well.
I assure you, concerns like these are being addressed 'behind the curtain.'
You might not see the results until a ship takes a hit... but you'll know they are there when the battle reports come out- or if you ask about something specifically, like you just did.

12" casemates would be more a hindrance than anything else.
1.) They would likely only fire about once every 3rd turn or so.
2.) They would also be very, very slow to traverse.
3.) you couldn't really armor them heavily enough... they would be very bad about blowing the ship up.
It is theoretically within the rules, and I would probably allow something like that to be built... if only to see how many turns it took before it exploded. ;)
Yeah, I don't think it's a very viable design either, so far the better BBs I've seen have been 15,000 tons or smaller, the only good 20,000 ton design I've come up with is the "BC" design I already posted. That one has potential.
And, at the other end of the scale, a small but useful little fellow.....

Ok... I know we are discussing this in another place, but I have to say it here as well:
Seeing this design makes me lean towards limiting these kinds of ships till much later.
Something about every ship in the world turning into an A-Q-Y layout ship with twin turrets disgusts me on a very fundamental level. While I prefer to allow everyone the maximum flexibility to design what they want, I refuse to have every ship in every fleet look exactly alike... and to have every ship from the smallest cruiser to the biggest battleship have the same identical A-Q-Y layout.
This isn't anything against you, but it is saying that A-Q-Y is starting to become a problem for creative shipbuilding.
KWorld,
Specifically about this ship- how long does SS say that the armor belt has to be to cover the machinery and magazine, and how far do the vital spaces extend (distance between the end of the fo'c'sle and the start of the quarterdeck)? I'm just curious, as I am trying to keep my machinery/magazines confined to within the vital spaces, and notice that it isn't quite working.
On this ship, SS3.3 is reporting that I need 114.68 meters of belt armor to protect the machinery & magazine spaces. That means that the machinery & magazine spaces extend well into the forecastle & quarterdeck regions, which isn't unusual in SS ship designs that are fast for their era. SS wants to put all the machinery & magazine spaces below the waterline, and will displace other things to do it.

OK, I was wondering if everyone had this problem or just me.
DAMN, do we need that engine slider working!
Looking at it, I probably won't be building any C06Ts, they're too big for the light cruiser role in the Columbiad Republic Navy. The Admirals Board is hard-pressed to support the building of a ship whose main armament is a 15cm gun that displaces almost 6000 tons. This should not be read to say that the board wouldn't support a similar vessel of smaller dimensions, however.
A ship along the lines of IJN Satsuma, though modified to fit CRN guns. I'm not keen on all the hull casemates, but with all the 25cm turrets cluttering the sides, there's no other place to put the anti-torpedo boat battery.

A ship along the lines of IJN Satsuma, though modified to fit CRN guns. I'm not keen on all the hull casemates, but with all the 25cm turrets cluttering the sides, there's no other place to put the anti-torpedo boat battery.
Two words for you friend- and I use this tactic all the time- TURRET TOPS! ;)
They just have to know when it is time to lay flat. :)
That would be appropriate for 70mms, MAYBE for 100mms, but not 150mm guns. 8)

I thought you WERE talking about the 100mm's! LOL!
I don't consider 155's an 'anti-TB' gun. ;)
The CRN is frightened of torpedoes, it wants TBs definitively stopped well away from it's ships, and a hit from a 150mm will do that. :)

The Lighter Carrier is a somewhat specialized vessel, which carries 4 35m cargo lighters on large cranes on either side of the hull. When cruising, the lighters are stored on the main deck, and they are swung out and lowered into the water when needed. The same large cranes used to lower the lighters into the water are also used to lift cargo out of the hold and then down into lighters tied up along side.

The Lighter Carrier is a somewhat specialized vessel, which carries 4 30m cargo lighters on large cranes on either side of the hull.

The same large cranes used to lower the lighters into the water are also used to lift cargo out of the hold and then down into lighters tied up along side.
And if those vessels are wind up carrying small torpedo boats in place of lighters... well, stuff happens.
I like this idea.
Excellent merchant ship, and also a crafty auxiliary.
Such things COULD happen, though the TBs would be limited in length to about 35m. I'll admit, the idea DID come from the torpedo boat motherships of the 1890s, I just turned it around to a use that has to do with the idea of "resource raids" on other islands and the need to land heavy equipment before there's a harbor.

And also a logical start for a progression to one of today's LASH (lighter aboard ship) vessels, where entire barges are loaded onto a vessel for trans-oceanic crossings.
MV Doctor Lykes, immortalized in
Red Storm Rising, is one of the more well known examples.
(http://www.photoship.co.uk/jalbum%20ships/Old%20Ships%20D/slides/Doctor%20Lykes-01.jpg)
Also, a 115'/35m torpedo boat could be built easily using the suggested very light torpedo craft rules I suggested.

Amusingly enough, if you back the speed down to 10 knots, the little thing actually can go 1200 nm, so it could self-deploy from one island to another, if you weren't afraid of it sinking in the first squall it ran into.

Whew... short legs for a liner, but a good ship.
Lots of people-moving ability.
3000 nm at cruise speed will get it anywhere it needs to go at game-start, cruising to any port on my continent is easy work, and if it's asked to run to one of your or Nobody's ports, well, then if it needs to an intermediate stop to take on and put off passengers and recoal can be arranged. Right now, there aren't any ports of call far to the south, after all.
If, however, a 4000 nm cruising range is thought desirable, here's a very similar vessel:

You're right with the points you made.
I'm thinking too much in line with trans-Atlantic liners. ;)
The first one fits the scenario... thinking a bit more, I would go with it.
The other thing that keeps our liners shorter-legged than historical liners is that we're more size-restricted than historical: one of the rules is that we cannot have a port that's capable of building ships larger than 25,000 tons normal, while RMS Olympic, a design contemporary with mine, had a displacement of over 50,000 tons. To carry 75% of the same passenger load at the same cruise and max speed on half the displacement, something's got to give. :)

Why not reduce some of the armor on that design, and possibly reduce the speed as well? The ship has more armor than many real life dreadnoughts had, and this ship is faster than many of our battleship designs by 5 knots. If it is being used as a battlecruiser (or other ship meant for use outside of the line) it has too much armor, and if it is being used as an armored cruiser (or other ship meant for use within the line) it does not really need all that speed. The armament is also rather excessive. If you make a few cuts in armor, speed, and armament across the design you should be able to shave a few thousand tons off the ship and make it more economical to build.
Are you sure that you could built 75% of the 19 000t BB before jan 3910?
If not, the BB 'll be scrapped ... :'(
Jef
you could still complete it as long as it does not violate the treaty, which this design does not.
Jef,
No, it won't be scrapped, you and I corrected Walter on that earlier. It's following all treaty rules, so no reason to scrap it.
Delta,
I already have slower designs with similar armament and armor. This is a large armored cruiser, intended to crush normal armored cruisers and it can, in a post-1910 scenario when battleships can have turbines, move to a 23-knot battleline without too much issue (the broadside will likely be lower, granted, than newer vessels, but that's the way of the world).
Perso, In the 2 last years,
I built light ships.
1908 -2xCL5 & 12xDD3
1909 - 16xTB4 & 6xCGB4
That's particulary interresting for CL, DD & TB because, engines technos allow higher speed.

QuoteThis is a large armored cruiser, intended to crush normal armored cruisers and it can, in a post-1910 scenario when battleships can have turbines, move to a 23-knot
That's why my last ACs are 23kts & 25kts.
Faster ACs are not a problem.
Speed increase for all Cruisers. ACs too.
So, a 14000t cruiser is always stronger than a 11000t.

The Auxiliary Lighter Carrier is a specialized vessel which carries 6 35m cargo lighters on large cranes on either side of the hull. When cruising, the lighters are stored on the main deck, and they are swung out and lowered into the water when needed. The large cranes used to raise and lower the lighters are also used to swing loads up from the holds and down into lighters alongside the ship (the 3 cranes per side weigh 110 tons each).
The Auxiliary Lighter Carrier, as opposed to its civillian cousin, is intended as a troop and supply carrier for expeditions that are founding colonies. The below-decks miscellaneous weight provides berthing & equipment space for up to 2000 soldiers (1 regiment), + 1000 tons for additional supplies and pioneering equipment such as steam tractors, steamshovels, etc.
8 steam launches and 20 large lifeboats are carried to facilitate initial landings before the lighters deliver their loads.

The Landing Ship is a specialized vessel which carries 6 35m cargo lighters on large cranes on either side of the hull. When cruising, the lighters are stored on the main deck, and they are swung out and lowered into the water as needed. The large cranes used to raise and lower the lighters are also used to swing loads up from the holds and down into lighters alongside the ship (the 3 cranes per side weigh 110 tons each).
The Landing Ship is intended to act as a troop and supply carrier for epeditions that are landing on unfriendly shores. The below-decks miscellaneous weight provides berthing and storage space for up to 2000 soldiers (1 regiment), plus an additional 1000 tons for additional supplies and equipment.
8 steam launches and 20 large life boats are carried to facilitate initial landings before the lighters begin delivering their loads.

The Lighter Carrier is a somewhat specialized vessel, which carries 4 35m cargo lighters on large cranes on either side of the hull. When cruising, the lighters are stored on the main deck, and they are swung out and lowered into the water when needed. The large cranes used to raise and lower the lighters are also used to swing loads up from the holds and down into lighters alongside the ship (the above-water miscellaneous weight is nothing but cranes) and the reverse.
In government service, the cargo capacity supports 2 battalions of troops, with an additional 500 tons of supplies carried in the cargo hold. 4 steam launches and 8 large lifeboats are carried to support initial landings before the lighters begin bringing in heavier equipment.
A small but useful little vessel.

The Large Lighter Carrier is a somewhat specialized vessel, which carries 4 35m cargo lighters on large cranes on either side of the hull. When cruising, the lighters are stored on the main deck, and they are swung out and lowered into the water when needed. The large cranes (4 cranes each weighing 110 tons) used to raise and lower the lighters are also used to swing loads up from the holds and down into lighters alongside the ship and the reverse.
In government service, the cargo capacity supports 1 regiment (2000 men) of troops (8000 tons misc. weight) with an additional 1000 tons of supplies carried in the cargo hold. 4 steam launches and 8 large lifeboats are carried to support initial landings before the lighters begin bringing in heavier equipment.
Hopefully final tweaks of the 3898 protected cruiser design.

I guess that a superfiring gun would always be above deck...
If I understand the layout correctly, the superfiring X turret is simmed as aft of the midbreak, so it should be above deck and superfiring. If it was simmed as forward of the midbreak, then it should be above deck and non-superfiring.
Currently, the X turret (which is supposed to be before the mid-break, rather like an UK R-class BB) is simmed as above-deck and superfiring, which I don't know as right). I'm not seeing any way to denote superfiring separately from above-deck, though.
Quote...3 x Twin mounts on centreline ends, majority aft
1 raised mount aft - superfiring
1 x Twin mount on centreline, forward deck aft...
You have no forward turret on the foredeck ?
Your fore turret is behind the bridge ?

No. There's 4 turrets: A (in front of the bridge, not superfiring), Q (behind the bridge, not superfiring), X (aft superfiring, before mid-break), Y (aft, not superfiring, aft of the mid break). Q turret is the one called out separately as "forward deck aft".
QuoteCurrently, the X turret (which is supposed to be before the mid-break, rather like an UK R-class BB) is simmed as above-deck and superfiring, which I don't know as right).
To me it looks the right way to do it. I think the alternative way would be to just use two turrets fore and aft and two turrets on the fore deck aft and not use the superfiring option for X. Not sure what the difference between the two would be without having Springsharp around.

Putting 2 turrets fore and aft and then putting 2 more on the fore deck (no raised turrets) results in a savings of 3% composite strength over the previous design.
A possible look forward to 1912, with what could be considered a light battlecruiser (OTL) or a newer, faster armored cruiser (TTL). It's a bit smaller than SMS Von der Tann, but the layout's more like Kongo or Derfflinger (though the secondary 15cm guns are in main deck casemates vs below-deck casemates and the underwater torpedo tubes have been replaced with deck-mounted tubes because the ship will be going too fast at battle speeds to use the submerged tubes).

This is the design the CRN was looking at laying down in 1910 to start replacing the old 1895 battleships. Layout is AQXsY, similar to the CRNs standard AQY layout but with one additional 12" twin turret aft superfiring over the Y turret. Speed has increased greatly from the old BBs, going from 17 knots to 23 knots (the same top speed as the 1900 & 1905 ACs).
