Thanks!  Now its off to bed...gotta design a couple of coast defense ships for the Baltic and a few groups of destroyers before I'm all caught up to 1910.
Do not forget the minesweepers and minelayers! ;)

I still like the LBB project better, also try and make sure you draw them in a uniform scale (gives you a real idea if everything you cramed on will actualy fit) SS dosnt actualy deal with the space issue, all it cares about is the tonage (which leads to things like one of my early 1K ton destroyers with 6 5" guns in singles with 9 20" torps in 3 tripple mountings midship)

It is drawn to a regular scale...everything is one pixel = one foot in my primitive drawing.

KK just wanted to make sure (will save you getting jumped on later)

Nice ship, and excellent drawing!

I'd say the cagemasts are too tall. The observation platform should not be much higher than the top of the funnels.

Hmmm...I was drawing them at the same scale as the OTL American battleships' cage masts.  I wonder if they didn't have observation platforms part-way up the mast.

look at the cage I did on the LBB Proposal, its fairly acurate....

The top of the platform on Volodymir is 160' tall. The top of the cage masts on the US dreadnoughts were at 120-130' according to drawings in Friedmann. So they are a bit too tall, but not as much as I thought it at first look.

Masts look better.
Turrets not too big for 12" triples? They somehow "look 15" to me
Maybe a straighter bow?

I like my bow just canted forward on a sheer aesthetics level.  :)

The 12" guns might be a bit big, since I don't know the exact length/height of the 3x12" turret mount in Gangut, which is what I'm basing my triple mounts off of.  They're done off of guesswork, really.

Borys

Could be that I'm used to twins ...

Yeah, I suppose I'm used to twins. Looking at the line drawing of Gangut here:
http://ship.bsu.by/main.asp?id=101251

I tried to imagine three such turrets on a smaller hull.
