While reading a number of Hoods' Crew members diaries, of the ships' shakedown cruise period, One stated that they reached a speed of 36-37 knotts at flank in good weather.
Their's a lot of different information on nearly all ships speeds, armour, armement and displacement.
Of course by the time of Hood V Bismark, as I said the Hoods' old reciprocating steam engines were, for all intents and purposes, Knakered and nowhere near capable of pushing her any faster than 28-30 knotts.
However she was re-fitted during her life, just not the full re-fit she was so desperately in need of.
As an example of mis-information, it's stated by many sources than Hood was not fitted with fire-control RaDaR sets, as I stated in my original post, She was, but her crew had no time to be fully trained on them, as her re-fit was cut short in order for her to leave port and intercept Bismark.
Also a number of sources rated Hood at ony 42,000 tonnes, This is also wrong, That was her last design displacement she actually went over that during construction by almost 7,000 tonnes, due to extra belt and turret face armour being added also thicker driveshafts were used.
A lot of the information on Hood is from design material and her original blueprints.
By the time Hood was completed she had gone through massive changes from her original design, and was a very different ship than was first envivsioned.
I would also like this oportunity to state my own feelings about the so-called flawed concept of the BattleCruiser, In short I dont think they were used correctly, Jutland was a disaster for the design, but only because the ships were used as Battleships were, ie in line ahead formation, this opened them up to long-ranged shellfire which directly falls upon deck armour.
BCs' were designed to be 'let off the leash' just as you would a guard dog, to get in close to the enemy vessel/s where deck armour becomes secondary to belt armour, ie close range fire is most likely to act upon belt armour and not fall upon deck armour.
Anyway, I wouldn't mind seeing a proper WWII version of the Queen Elizabeth in SH3 sometime
as all we have right now is the Revenge class which were not re-fitted, so the two classes looked very different come WWII
Here's a link to one of the most famous QE class BBs' which my Grandad was serving on during the Battle of Jutland, some good pics of her before and after her fe-fit, you can see clearly that her twin stacks became just one...
