So I've gathered data on actual speed for all the major power's current ships in OOB.
I used supply/transports as a starting point, using their 3 movement hexes as 15 knots. That is reasonable.
Then I simply divided all actual speeds with 5 and rounded down.
I think the resulting movement rates will provide more variety to similar classed ships and be more fun to play.
Aircraft carriers have a fairly high movement rate. But they would also be forced to be stationary when launching/retrieving aircraft. I think a good solution would be to force the carrier to be stationary in the game when doing this, at least when launching air units.
All data is from 'Conway's All The World's Fighting Ships' 1906-1921 and 1922-1946.
