Strength does not necessarily mean composite.

Which post are you responding to?

In my reply to you, I only look at cross-sectional strength because longitudinal strength is at 1.50, way above any minimum requirement. I've tried your suggestion after you asked and I've tried it before too. I typically don't like ships with very high L:B ratios even if it's completely accurate for a destroyer.

In my reply to Tan, 111 tons of weight can be translated to either cross-sectional strength or longitudinal. All you have to do is change the shape of the ship (since you have sufficient composite strength due to the reserve weight). If I changed speed, range, and length of my ship to that of Tan's design ceteris paribus, I instantly have 1.16 seakeeping (1.00 before) and 0.57 cross-sectional strength (0.50 before). With this additional strength, I can raise the average freeboard from 9.03 ft to 10.20 ft giving the ship 1.46 seakeeping.

Not gona get into it with you logi, if you cant accept a joke in the good humor it was meant in, well thats your loss.  I realised EXACTLY why my DDs ride so much better than everyone elses, however they are built to my needs not anyone elses (seriously think about it whats the farthest my ships are likley to go without coaling... Tranto to Alexandria?)

Oh, I thought it was meant seriously, my bad. :-[ As the years have passed I've realized I've almost completely lost my ability to discern seriousness from humor in a post.

A possible candidate for the next Iberian battleship. Given the fact that we are drowning in BP (or at least I am), Iberia can probably afford to build these. Since they will take 21 months to build, the actual cost of one is only $3 and 3 BP per half year. A set (4) will cost $12 and 12 BP per half year.

Whether or not the 14"/35 is an improvement on a 12"/40 is open to question.  But otherwise, it's a pretty solid ship, though I would either add another 8" turret per side or replace the 8" turret with 6" casemates, 2 guns per side isn't enough except at very close range.

[Jefgte]

I prefer the 8500t BB-18kts.
For the moment, 21kts for a BB cost too much in displacement.
Wait turbines to increase speed.
Have a uniform 18kts battle line is tacticaly interresting.

Honestly I think im the only one with BBs that do 20+ knots... (I blame it on me falling in love with the RE class things Italy built OTL).  It led to a whole host of aditional problems like what did I use as a fleet scout (hence the 23 knot ACs that are as big as my BBs), ofcourse it also led to some very interesting solutions long term, like my BBs and BCs (post Dreadnaught) will be aproximatly the same size as my BBs and ACs curently are.  So there will be no real change in my building plan.

[snip]

I think the main belts are to short at 7ft. They are nice and thick, but 7ft does not give much protection. I know it will make them more expensive, but they really need taller belts. Also, you might want to changed the armored decks to single deck as opposed to multiple decks otherwise your main deck is a bit thin (2" is prefect for a single deck for now IMO) aside from the obligatory comments about the shallow freeboard (which raising may help you get some more strength on this tonnage) and there ability to venture out into any sort of weather able to fight, the speed and armament of the design look to be competitive with the latest battleships of several nations.

[Logi]

Taller belts give odd belt heights vs deck heights and also 7 ft is plenty for a ship with a freeboard of 10 ft. I'll fix the deck section.

Is modification of designs still open? I want to replace my predreadnought's with this (same tonnage).

The increase in armament is fine, but there's a problem with the thicker armor: you've actually reduced your armor coverage.  If the main belt is centered on the waterline, you have 4' of unarmored sides above your upper belt, and your main belt only goes 4' deep below the waterline.

Better.  Now, the 4" guns: You've got a ship that's similar in size to USS Indiana, with slightly larger main and secondary guns.  Based on her design, you'll probably need to move all of the 4" guns either up, down, or behind casemates to protect the crews.

And look, this design HAS enough range to threaten New York..... and people think I''m paranoid.  Ha!  :)

[Logi]

That shouldn't be necessary. The design is 380 ft lwl whereas the USS Indiana was 350 ft lwl. Given part of the tertiary is already raised (4 out of 12) there should be enough space to fit the guns.

Yes, it's all a dastardly plot to attack the US ;D

[Tanthalas]

AH HA The truth comes out... Dusts off War Plan Flouresent Clear *looks through it* "huh in case of war between Iberia and the US, Declare Neutrality, for further instructions see apendix C" *digs through till he finds Apendix C* "Sell ammo and Ships to both sides"  Ok now I know what to do you may begin your combat at any time.

That shouldn't be necessary. The design is 380 ft lwl whereas the USS Indiana was 350 ft lwl. Given part of the tertiary is already raised (4 out of 12) there should be enough space to fit the guns.

Is modification of designs still open?

No
