Iberian Navy

[Logi]

Since I'm of the thought process that higher speed is not useful if there are slower ships in the fleet - the capitals will only get faster when the fleet is larger enough or the amount of composite strength required for higher speed becomes much lower.

In other words, the fleet won't get incremental speed increases with successive classes but all-at-once leaps in speed.
For example, say everything in 1895-1905 is 16 kt in fleet, then after the standard speed becomes 24 kts - so on.

- Also thanks for the calculation KWorld. So I'll just subtract 7k ton from my starting amount.

[Logi]

A protected cruiser - There wasn't a feasible way to reduce tonnage while having the same firepower and engine speed/range.

4 kts faster than main fleet with two British 9.2"/40 guns. The additional 1000nm range allows it to traverse the African's colonies more easily.

this ship... im not sure what it actualy is you called it a PC but you left out the side belt we agreed was necessary to sim a PC long long ago, but then you did use BB/AC layout rules on the guns so technicly its an AC but that unarmored freeboard looks unwise... well unless you plan to drop em down around 1K tons then who cares

Let me this straight - protected cruisers need a side belt but aren't allowed turrets.

Then what's the difference between protected cruiser and a light cruiser? What advantage does it have? I thought the advantage was that the turtle-back deck allows you to have no side belt (coal serving as buffer) - abet at the expense of the protection of everything above.

In fact in DF's Netherlands design thread he posted a design with no belt and single turreted 8.27" guns. You responded:

*checks his pulse* Yup im still alive... DF im impresed, its slowish and has armor (although with the lack of a belt I assume its a PC) a great departure from what us vets had come to expect from you, and here I am planing to produce a 20+ knot battleship with tinclading (oh how the roles have reversed eh I honestly expected a version of your super cruisers).

Since you defined it in that thread through your rely that a ship with turreted 8.27" guns with no side belt is assumed to be a PC I thought my design fit into those standards.

I'm not sure on the difference then - I've never had to sim them either during N3.

[Tanthalas]

PCs are suposed to have a 4' high belt to simulate the turtlebacking (since SS3 like SS2 assumes all decks are flat even if you pick protected deck) the guns are fine though, I was more rambling and trying to figure out where the ship fit.  Posibly the rules have changed on the 4' tall belt but I didnt notice anything changing them.

[KWorld]

In 4.5 we were using 5' high belts to simulate the turtle decking.  This is, effectively, a very small version of one of the British 1st class protected cruisers, or a baby Garibaldi or Cristobal Colon.


On the ship itself, the layout of the 3" guns won't work: the deck mounts will be in the way of the casemates.  Either the deck mounts need to go up a level, or the casemate need to go down, or something. 


A real eggshell armed with a sledgehammer: against other cruisers, the only weapons she has that will sting are the 9.2s and the torps, the 3" guns are too small to do much, and are short of ammunition given their rate of fire.  The 9.2s, on a small ship like this, are probably going to have a hard time.

On the ship itself, the layout of the 3" guns won't work: the deck mounts will be in the way of the casemates.  Either the deck mounts need to go up a level, or the casemate need to go down, or something.

I'll fix that.

A real eggshell armed with a sledgehammer: against other cruisers, the only weapons she has that will sting are the 9.2s and the torps, the 3" guns are too small to do much, and are short of ammunition given their rate of fire.  The 9.2s, on a small ship like this, are probably going to have a hard time.

The thing is looking at her competition (the same size) she has larger main guns (9.2" vs 8.27" or 6") and comparable armor, speed, and ammo load.

So a slight change - addition of 6" secondary with reduced number of 3" tertiary.
Protected deck corrected by inclusion of 4' tall belt.
Tonnage increased by 300.

A 24cm deck mount?  That must be a fun thought for the gunners.  Not to mention a terrific fire hazard, with those big powder bags in lockers on the fore and aft decks.

Agreed, mount and hoist definitely needed!

[Tanthalas]

Per the rules it requires a turret or a turret on a barbette... thing would be a bear to turn, or load on that small of a deck, after all tis a 25+ ton gun.  The 9.2 british was a 25 ton gun(and from what I can tell only ever turret mounted) so I assume a 9.4 would be heavier... Not fun seams a mild description.

The 24cm Krupp gun was also only ever mounted in a turret, same with the 24cm Guillen gun from Spain.  The 24cm Guillen was a 22.5 ton gun, not counting breech, while the Krupp gun was a 24 ton gun.  So yeah, not fun.

Ya, this design will need a turret if it retains that gun.
