There are a number of those designs that have the " Main belt does not fully cover magazines and engineering spaces" remark. I am not sure if Iberian Naval Officials are concerned about that issue... Other than that the only other thing that I notice that a few of your designs have different shells per gun for the various calibers (like the 120-140-150-180-250 on the Tristan De Luna and Francisco Pizarro Gonsalez), but others are at the Springsharp base value of 150 for all their gun calibers.
Also, make sure you are using the right type of engines.
Thanks, Walter and Snip. Changed some data in my designs. ))

I need to make sure this is added to the Ship Design Rules, so woops on my part. The TDS option 'Strengthened structural bulkheads' is broken quite badly, to the point where we cant use it. You need to use the 'Additional Bulkheads' option.
Aside from that, I think 24m is to narrow for a effective TDS, especially with wing turrets. Can you describe the layout better?
Snip, I've just tried to simulate additional armoured section between inner and outer side plating
Something like that:
(http://ic.pics.livejournal.com/solo_ad/69128334/11782/11782_1000.jpg)
Im not saying what you want is wrong, Im saying the Spingsharp code behind the option you chose is completely broken. It does not deduct strength, but just pulls from the hull weight with no indicator that its doing so outside of that section of the weight distributions. We discovered that bug when someone here (might have been me), made a ship with -25% weight in the 'Hull, fittings and equipment' section. So in order to get Springsharp to do the correct calculations with the TDS, you need to use the Additional Bulkheads option regardless of what you intend your TDS to look like.
hmm was just poking my nose in, don't really have time this evening. I keep meaning to find time to look at other folks designs.
1) didn't know that about the strengthened bulkheads vs. additional. Wonder if that effects any of my designs.
2) 24m for a twin 280mm with a functional TDS ? As observed previously, many of the British/French beams reflected partial TDS or shallow ones, or both. The Germans had effective ones. Von Der Taan was 26.6m with twin 280mm. I could see 25.5 or 26m because you have a high BC, but 24 seems a little narrow for an effective TDS
2b) However, you may be aiming for a Provence style TDS of a 1m passage backed by an 8mm bulkhead - not really functional except versus leaks. That should allowable- to make an interim design that doesn't necessarily work. However, this also brings up the 5mm bulkhead- I've never seem 5mm in a design, 8mm is the least, and 18-19 for flexible bulkheads or 20-40mm for armored holding bulkheads a more reasonable range.
2c) I'm guessing that main belt is just long enough to cover the engines, which means the TDS is not.
3) The wing turrets are artificially 'cheap' in SS, they actually needed structural steel to support and disperse the outboard stresses, and complicated side protection, but they are neat.
4) I don't think 50mm is an adequate upper belt. We're not at the all-or-nothing phase, this is a capital ship, that upper belt is supposed to stop intermediate guns. 50mm will keep out HE, but If Semi-Armor piercing rounds can penetrate ~2/3 their caliber in bursting condition, 50mm will stop 75mm...which is tertiary, not secondary. Oh, and as a trivia matter, you can't faceharden plates that thin effectively. Effective facehardening can be done down to 100mm early on, then Germans went down around 88mm later. This reasoning is why my 1908 AC has 100mm upper belt- face hardened and will stop up to ~150mm SAP rounds, and a 50mm end belt- meant to exclude HE rounds or stop shell splinters from making a sieve of the bow at the waterline.
5) 8000nm at 14knts? That's a very high cruising speed for pre 1920.
6) Laying this down in 1906 means fire control requiring 177 tons started development in 1905 and finishes development in 1907. I don't think it's unreasonable to plan some misc weight for that.
7) 25knts? Times like these I kinda wish were posting by year so I could "react" to this. My 1908 design is about 1000 tons less, only 25.5knots, with fewer & smaller 10" main guns and slightly less armor..oh and the same beam 24m. Oh, and additional bulkheads toggled :)

Technical Comments: Your 1906 battleship is too early for triple turrets. The tech does not complete until 1907, and it takes an additional 18 months to design the mount. The earliest we can see triples is 1908. Also, check your main battery layouts. I noticed some looked weird. There are also some unarmored ends that crop up.
Other comments: Nice set of designs. I can see a clear evolution going up the line. For my taste, the range is too high while the armor does not give a ton of coverage compared to there contemporaries. I would drop the range to 6000nm to 6500nm range (this would still have them be in the upper tier in range) and increase the height of the main and upper belts a bit.
Thanks, snip, for commens. I've changed some data in my designs. Here trey are

Couple comments on those last three battleships (I'm probably not going to have time to fully review the batch package for about a week)
General Things: The ships have an extraordinary amount of TDS depth for this era. While it is not strictly illegal, I really don't like it as I think it's cramping the hull to much. The thickness of the TDS is also low. The ships also have a very extraordinary range for the time period and environment. All the designs have a uniform thickness of armor on the deck for the whole ship. All of these things contribute to the large size of the ships compared to contemporaries (eg the Roman Praeventores class, layed down in the same window as the Joan De Bourbon weighs in almost 6000t lighter and has better armor protection. While the Praeventores trades the 24knts speed for 21knts and Electric Drives.)
Santisima Trinidad: Aside from the things mentioned above, this is a solid ship. Correcting/Adjusting the TDS and Range should provide improvements. Snip's Suggestions: Decrease range and adjust TDS beam to provide more interal space. Decrease thickness of non-citadel deck armor to increase the length of end belts to cover the whole ship.
Iberia (New): Where to begin here, aside from the things mentioned above. It's clearly an evolution of the ST, which is nice. But this takes a turn for the concerning. Trying to cram ten twin 152mm turrets (which I am not enthusiastic about appearing this early at all) on the deck with the twin 305mm turrets is madness. I would very much like to see a drawing of the proposed arrangement to better understand its failings. On a 170m hull, there is just not enough room for everything. Snip's Suggestions: Move the 152mm guns from turrets to casemates. Use savings from this to improve TDS thickness. Same modifications as the ST
Joan De Bourbon: First, this thing is a damn monster. Same comments regarding so many turreted secondaries as the Iberia. Where the other designs have long, but not super unreasonable, range this thing is just unrealistic. The end belts are so thin they may as well not exist. The TDS depth is reasonable, if large, but the bulkhead thickness is very low. the 24knts speed does not buy you much over the 23knts of the previous ships. It also does not carry enough weight to fit a fire control system, so all those big guns will not be hitting anything at the ranges comparable ships can put the hurt on her, which with her thinner armor is a flaw she cant ignore. Snip's suggestions: Decrease the massive range, use savings to provide Misc Weight for Fire Control and other things. Move 152mm guns to casemates, use savings to improve end protection. Knock speed to 23knts and use savings to improve armor protection.

After thinking about it, Im really dissatisfied with the T&B mountings for the 152mm guns on the later battleship designs. It's far to early for them, as our cruisers cannot even mount them yet. I'm less opposed to M&H, as those come with some serious drawbacks for larger guns, but would prefer casemates for this era.
I have noted too

QuoteCapital Ship Architecture:
Baseline: Main guns in twin turrets, secondaries in casemate, tertiary in casemate or deck mounts.
1891: Mixed-caliber main battery (Main+intermediary calibers), Superfiring secondaries (Restricted Axial Firing Arcs) and Stacked Main Battery turrets OR Main caliber battery in AQY. [Pick One Only]
1903: All-big-gun ship with wing turrets OR Superfiring turrets (restricted axial firing arcs) [Pick one or both]
1905: Improved turret hydraulics, independent gun elevation, Torpedo Bulkheads, triple turrets
1910: Superfiring turrets (unrestricted firing arcs), "All or Nothing" Protective Schemes, "Pair of Twins" Quadruple turrets
1914: True Quadruple turrets, Sloped external belts
1920: No restriction (high or low) on caliber of turreted guns
1926: Primitive DP secondary batteries
1932: Improved DP Secondary batteries. De-Capping plates
1940: Advanced DP Secondary batteries.
1946: Automatic Secondary Gun
...
Cruiser Architecture:
Baseline: guns in single mounts or casemates, on side/centerline
1900: ammunition hoists, deck torpedo armament, superfiring mounts. Cruisers under 6000 tons may have cross-sectional hull strength > 0.9
1910: twin gun mounts (require hoists); powered gun mounts; unrestricted weapon armor
1920: No restriction (high or low) on caliber of turreted guns. Cruisers under 3000 tons may have cross-sectional hull strength > 0.75
You can't use this techno before 1912.

1900: ammunition hoists, deck torpedo armament, superfiring mounts. Cruisers under 6000 tons may have cross-sectional hull strength > 0.9
1910: twin gun mounts (require hoists); powered gun mounts; unrestricted weapon armor
1920: No restriction (high or low) on caliber of turreted guns. Cruisers under 3000 tons may have cross-sectional hull strength > 0.75

1900: ammunition hoists, deck torpedo armament, superfiring mounts. Cruisers under 6000 tons may have cross-sectional hull strength > 0.9
Re SS your cruisers < to 6000t laid down in 1902 & later with Overall 0.9
Have a look on Parthian or Roman cruisers.
For exemple, the Lauri class "Overall is not 1.00 but 0.9"

OK. I have cross-sectional 0.93 and I think it is corresponds with rules. and overall 1. I understand this rule as on 6000 t cruiser you must have no less then 0.9 in cross-sectional hull strength.
