and yet another version Ditched the 57s, let it gain 500 tons and added another pair of 4.7s its a touch slower but over all I think its proly an improvment as its numbers are alot better.

and quite posibly the final version, I did away with the deck armor compleatly (face it a 1" deck was a waste of tonage) added another 4.7" (5 total now), got it up to 20 knots and down to 1200 tons.  all in all I think they would be not bad little cruisers.

I think at this point you'd be stuck with fixed above water mountings, I'm not aware (though certainly willing to be enlightened) of any twin rotatable tubes at this time period.

[Tanthalas]

dosnt realy matter either way as it has no impact on the ships tonage/strengths and it has plenty of deck space but I can make the changes easily.

Just for Kicks and giggles I was messing around with a 22 knot battleship tonight, this is what I came up with (if I build it or not its still a interesting ship)  I could proly do more with it if I lowerd the freeboard and switched to my "standard" 11/40 but this was just for kicks like I said.

*NOTES*
Ships in Class
RMS Nike
RMS Mars

Both ships Built in German Yards to Italian Specifications

Crew Consists ot 20 Officers, and 320 Enlisted Personel

Misc Weights
44 tons on deck represents Aditional Facilities for Colonial Flag requirements and building reserve
6 tons below watterline to account for torpedos & reloads

[Jefgte]

You could probably limit the lenght inf to 120m to have dockyards facilities in colonies.
Reduce the beam too, 6.71m is too much for that kind of ship in unknown waters.

If it's a protected cruiser why does it have an armored belt?

[Logi]

If it's a protected cruiser why does it have an armored belt?

Protected cruisers are to be simmed with a 4' tall belt.

[Tanthalas]

What he said, as I have explaind multiple times Spring Sharp dosnt sim PCs very well because even if you select protected deck it sims all decks as flat.  So to remidy that we use a verticly chalenged belt of the same thickness as the deck armor

If it's a protected cruiser why does it have an armored belt?

Protected cruisers are to be simmed with a 4' tall belt.

I thought it was the upper belt (reasonable to not the a waring, because my engine room is longer than the ship), and it represents how much thicker the slooped portion of the deck is? So far I have also used the normal 8 feet for such a "belt".


Not that it matters, but shouldn't a German import use German weapons?

[Tanthalas]

I just used my standard weapons on it (mostly because im drawing it and I already have the 4.7 and 8" guns drawn) as to the engine longer than ship issue, I always figured that in situations like that boilers and stuff were on the wether deck level (ala how the original lexington would have been)
