You might want to check you gun placements. Seven guns in three mounts is not that practical and I'm not sure if small (6") guns can be put into twins before the 1920s or so.
the rule states
1910: Twin gun mounts (require hoists); powered gun mounts; unrestricted weapon armor
so the earliest you can have a 6" twin (using a mount and hoist style mount) would be 1912 H1. I had a similar idea but realised it was a non starter.

There are actually 7 mounts on the first Boulder, the first 3 are on the centerline, the other 4 on the wings.

Ah, well, real ships can't be built. :)
Quotethe earliest you can have a 6" twin (using a mount and hoist style mount) would be 1912 H1.
The rules also state...
QuoteIf research of a technology is started before the listed year, for every two years difference from the game year, the research will take six months longer. This time is added to the months prior to success chances being rolled.
... so, unless I read it wrong, H1 1912 is not the earliest you can have a 6" twin mount. You can have it before that...
... but you still have to research the tech before you can build that twin mounted USS Boulder.
@ Kworld yeah I have run into that in the past... repeatedly
@ Walter OOOOOHHHHHHH I had forgoten all about that part of the research rules *starts researching somthing FUN in H2 1900 and reviews his wierd ships plans*

and the fuzzy area of legality returns...given its a 1902 design, Im going to hold off on commenting on such.
The USN doesn't have a 7" gun available, and if it wanted to develop one it would be mid-1902 before it would be ready. So deploying such a weapon before then's not feasible. Of course, the USN had one historically, though it never mounted it in any fashion other than casemates on battleships and on land.
The twin mount and hoist is the sticky point here. Technicly, that is not allowed until the 1910 cruiser tech. Now if they were in T&B, its a different tin of kipper.

AXY, actually. But it is a thought....
or you could use single mount and hoist mounts and give it say wing turrets.

That's essentially the current (1899) design: 1 bow centerline mount & hoist shielded gun, port and starboard mount & hoist shielded guns, 2 stern centerline mount & hoist shielded guns (no overhead or side armor on the mounts, just the gun shield and hoist armor).

IMO,
These small ships could be built in 70m SL.
Reserve 120m SL to scout cruisers.
Jef ;)
I could, I'm sure, but I have 15 S1s vs only 10 S0s, and only 5 D0s vs 15 D1s. So I'm not sure it's worthwhile.
This is just to optimize the use of industrial shipyards resources...
Jef ;)
Heh, the way I'll probably optimize those is to enlarge most or all of the S0s to S1s. :) That way they'll be useful for later, larger DDs, which 70m S0s aren't.
Hey thats my trick... *hides the fact that he is updating all his slips and docks*

You'll have turbines in 1904...
1904 is probably the first year to SS with turbines.

First year assuming you get a lucky roll, 1905 would be the "safe" bet.

Turrets are laid out as ABs XYsZ (X turret faces forward, with it's back to Y).
Thinking about kicking off the standards a few years early? Supose that means that USS Wyoming will be a "Standard" instead of the turret farm arangement of OTL =P (since she layed down in 1910 OTL)
Haven't decided whether there'll BE Standards in Navalism, yet. :)
I just would like to see us try to avoid the Gun Creap that happend in N3... was realy annoying to have to laydown 14" ships in 1909 when some of the greatest ships ever built were being layed down with 12/50s OTL (it led to me building several ships I realy didnt like just to keep up).

I don't know that you'll really be able to avoid it, especially given the over-armoring that's very tempting to do. Given that the 12"/50 and the 14"/45 techs become available at the same time, you'd need to have a reason to develop the 12"/50 (the US might want to use it as a BC gun, instead of the heavier 14"/45, for instance).

Oh I agree, its an issue. OTL the German 12/50 and British 13.5/45 (Course the first units using it wernt layed down till 1910) were aproximatly equal however the US 14/45 was a Superior gun to both (but its first units wern't layed down till 1911 if I remember right). In the Nverse we end up with people using them on ships with 1909 laydowns becasue frankley well they can... hence Gun Creap, I dont honestly know the answer I do know part of the problem is SHP restrictions but honestly we need them (much as I hate to admit that). I do wish I could figure it out though casue I realy like 12" guns ;)

Not sure how the SHP restrictions are an issue, myself. But it makes sense to stay with the lighter 12" gun IF it will get the job done, and to drop it in favor of larger weapons if it won't.
Thing is, we're already starting to see "gun creep", with the German submissions of 35cm guns to the Brazillian and Chilean competitions and the RN working on 13.5" guns (albeit more howitzers than naval guns).

France didnt considers this type of cruiser as interesting in the futur.
The composition of the Marine organized around fighting groups consisting of battleships (12 "guns) and powerful cruisers (10"78 guns). Scouting Forces consist of small light cruisers.
The USN is frustrated with smaller cruisers. At least until turbines make a useful appearance, smaller cruisers suffer from being no faster than their bigger brothers, which makes it hard to use them for scouting (oh, look, you found a smoke plume, and it turns out to be an armored cruiser, which is as fast or faster than you are: either you run away and cannot learn more about what's behind it, or it sinks you).
The other thing the USN is trying to do is fill a gap in it's production line. 1902 is likely to be a pause year in USN production, while the new designs from the 1900 class shakedown and reveal their issues. The USN would like to wait on heavy ship construction until these issues reveal themselves, so fixes can be made to follow-on units.
I feal your Pain Kworld... What I wanted to build got shot down, and now im looking at a hole in production around 1903. I also would like to build smaller cruisers (I think of them as CLs but they realy arn't as they have some armor), but I just cant justify them when larger cruisers are curently so much more capable.
I could build these instead of Boulders, but I don't see a good reason to do so.

more or less where I ended up for a Colonial cruiser, I used 7.5" guns and I think I ended up at 7500 tons light but yeah same problem The diferance in preformance between them and the Gladius type ACs is just to big.

We'll probably be stuck in this spot for a few years, until the turbines start becoming viable engine types.

I could, I'm sure, but it wouldn't improve them vs their larger competition. Shortening them would almost surely drive up their weight, putting them closer in cost to units with the same speed and substantially superior armament and protection.

Below-decks miscellaneous weight includes provision for 4 18" submerged broadside torpedo tubes with 12 reload torpedoes.
Above-deck miscellaneous weight allows for a long-range wireless installation.
You have 6 turrets installed on the centerline.
Difficult to instal engines & boilers.
IMO, hard design for the enginers...

Nope, only 3 turrets on the centerline, the 7" mounts are atop the 12" turrets. Just like on the Nebraskas, or the historical Kearsarges and Virginias (though the historical ships only had 2 12" turrets, vs 3 for the Navalisim ships).
its a nice ship but remember our discussion about MMB or AQY. I would suspect that 7" guns would fall into that grey area but that this ship would end up being ruled MMB on AQY (Ilegal).
I don't think so, since the rules specifically say: "Secondaries are 4-7" guns. 8-10" medium-caliber guns are not secondaries, but medium-caliber main guns". Guns between 7" and 8" are in a grey area, 7" aren't. At least by my reading, anyway.
Im just giving you my opinion, but like I have said in the past, feal free to build whatever you want. Just dont act surprised if there are repercusions.

If it does, it does, and I can save a few tons (and end up with a ship that works better). The 7" casemate mounts will only be better here in that they're mounted higher and so are less prone to being washed out than the historical mounts. That won't change the fact that the shells are really too heavy for easy manual operations, but in 1903 the USN won't know that.
A possible test-bed for the 7" gun. It's a conversion of an 1895 cruiser, taking the opportunity to pull the old engine and install a new, more modern one along with the replacement of the old 6"/40 guns with 7"/45s. The old torpedo tubes were replaced by a short-range wireless, and the 4"/40s with 4"/50s.

If it's operating as part of the battle line you don't really need it to go 22 knots, unless it is going to work with the armored cruisers. If it does work with the armored cruisers it should probably resemble them as well, otherwise it will become quite the shell magnet.

It needs to be able to go faster than the battle line to achieve a useful firing position if the enemy is respecting the range of torpedoes (as the USN expects to do). Visually, it looks like a longer Boulder-class light AC.
