There doesn't seem to be a detailed naval section on the wiki that answers these questions.
I know theres a number of ships in a fleet were by any additional ships will lead to no increase in fighting ability (25?). However is there an optimum number of ships to have in a fleet?
Also is it best to mix fleets up or keep them homogeneous with your strongest war ships?
At what point is it worth getting rid of your older ships if ever? i'm aware that there are classes of ship as tech increases which have an unseen advantage over older types e.g. commerce raiders can beat men of war.
Any other tips
