Nice drawing & good global concept ...
IMO, Forecastle is certainly too short, not drawing at 20%
The bridge & funnels are too near the bow.

;)

[Tanthalas]

it should (note I say should not is) be within 1 or 2% of 20% (unless I was totaly brain dead which at the point I was working the front of the ship is a posibility)

and while I agree compleatly on the stack issue, I couldnt find anyplace I actualy liked the way they fit.  What it needs is another stack aft, but there just wasnt anyplace I could put one I actualy liked.

[mentat]

  - the DD - forward superstructure is high as well as far forward - not sure it looks very stable - would really sink into trough of big waves

but I like Fast BB a lot - very nice - suitably mean, powerful and fast  ;D

[Tanthalas]

While not armed with the new 15.5" Naval gun (storyline reason youll just have to wait) This new generation of Battleship will provide needed balance to the Fleet (it gives me 12 14" armed ships instead of the curent 10)

the Fast BB looks great :) - why not build more of those - won't they be better investment in the long run?

Not to get in your way, or anything, but I think that it would work better with triple 9'', 12 on the centerline and 6 on the sides.

Did you just seriously say it should have 4x3x9" on centerline and 2x3x9" in wing turrets?

[TexanCowboy]

......... yessss.... :-[

[Sachmle]

......... yessss.... :-[

Can you say "FLOATING AMMO HULK" and "GOLDEN TWINKIE"?

[TexanCowboy]

Yeah... but that does sound entertaining.   :)

Back on subject, now, doesn't Rohan have a triple 12''?

Golee Gee, I dont know... I supose I must since I have 6 ships with tripple, 12/50s on them already.....
