Ok so I Have decided to split it and (maybe) make 2 one realistic and one ASB.
I'd never go with the 20/20 hindsight. That'd be terribly unfair to the original designers and constructors.
I totaly agree but since we are annoying little bearded ones lets stamp on them shoulders
!
My ASB Dreadnought
After some springsharping I got the weight down quite a bit and she is now smaller (nearly 2kt ) and cheaper (well before all the expensive stuff in the masts
) best of all she if probably faster ( she is supposed to be 21Kn but she has 25,245 SHP v 23,000 SHP in the real ship and she is smaller so I think spring sharp is underestimating her speed ?)
Still has a broadside of 8 12inch and 4 forward and 12 x 4.7 is probably better v torpedo craft in my opinion

Any opinions before I finish her off ? and then I will go think hard about a realistic one.
