There should be a number of improvements to the naval aspect:
1. Ships should move further per turn to represent better their speed relative to land forces. (I also think maps should be significantly larger and have more islands).
2. Naval great leaders (with Admirals/fleets, too) should be available as well.
3. The AI needs to have better understanding of and use of seaborne invasions, with more massing of ships and troops.
