Bismarck and Prince Eugen replaced by...

It's in the logs at the time of the Bismarck chase. This is the highest speed I know of that was recorded on a KGV-class BB. The trials showed the following results:
KGV: 28.0kn
PoW: 28.0kn
DoY: 28.3kn
Anson: 27.62kn
Howe: 27.5kn
So DoY exceeded 28kn on trials, but the average for the class was about 28kn.

Howe: 27.5kn

However, these speeds were achieved with an average of ~112000 SHP, but RN ships were typically engineered to withstand overload powers much greater than are produced during trials. This is from Allied BBs:

PoW, prior to intercepting Bismarck, "...steamed at overloads of 128000 to 134000 SHP with no difficulties...(D&G page191)"

These are from PoW's log on 24 May 1941:
0500- Log: 295.2; Distance Run through the Water: 28 miles and 8 tenths; True Course: 240; Mean Revolutions per minute: 235.8 .
0600- Log: No readings taken following action; Distance Run through the Water: 29 miles and 1 tenth; True Course: Var (various); Mean Revolutions per Minute: 239.
0700 listing is 28 miles and 4 tenths at 231.8 revolutions.

So we have G&D providing SHP data and then PoW's log entries, and it all adds up Holland pushing both Hood and PoW to over 29 knots during their run to intercept Lutjens.

I meant to point out the differences in the class as well as showing that more than 28kn were already achieved during the trials. I also think that the 28kn often mentioned for the class are a reasonable average, given the differences between the ships, their increasing displacement with the progression of the war and the varying conditions of the hull. I mentioned that the PoW did 29kn, but this imho is hardly representative for the entire class. I should have separated the statements by a paragraph. All in all I just wanted to give BlackBirdZGTR a bit better impression on the performance of the KGV class BB's.
