Dont forget that the limitation is 200BPs for the 1870 restart with all infrastructures...

Oh I haven't forgotten.  I still need some big ships to project power. 

[Walter]

Should your Flagship not be the one that does the projection of power for you? :)

[Darman]

Should your Flagship not be the one that does the projection of power for you? :)

Who fears a Channel Fleet with 12 2k warships and 1 6k warship?  My flagships will probably be major station vessels, they have quarters for an admiral (or ambassador/envoy/etc) and a 50-strong marine detachment.  They can be supported by whatever else is available but they pose a potent force on their own.  Additionally they may be withdrawn to serve in the Channel, since they are powerful ships of the line in their own rights.

Contradiction here, I think you mean 2 twin mounts.

Don't worry, Darman. You're not the only one to make that mistake. I noticed that with a few of my unposted sims I forgot to change that as well, so I will need to check them all before I post them.

Oh boy!  I'm glad I'm not the only one.  I was in the middle of a fantasy football draft when I posted that ship so I was a little distracted. 

I wanted to cover the entire 10ft freeboard with armor, so should I make my main belt say 8ft tall (1/2 below waterline and half above) and then my upper belt would be 6ft tall?

That's how I've been doing it.

I made her a little more seaworthy than her predecessor by about 5ft worth of freeboard.  I'm considering building two of these monstrosities; HMS Devastation and HMS Thunderer.

No deck armor?

No deck armor?

I was considering deck armor.  How useful would you believe deck armor to be during this era?
