It seems like the sea is one big highway to the AI, though I suspect there's some sort of range determination going on as well. I know a lot of Mediterranean factions have ships, but they've never come close in my game as England.

I think what need to be done is the AI set to attack overseas only when a piece of land close to the target is held or it's at war with the owner. Crete will be attacked if the AI holds part of Greece, Corsica & Sardinia if it holds a province in France or NW Italy. The Danes should still attack Britain of course... they were doing that well before the time MTW2 takes place. Basically just a simple mapping would do. Provinces X, Y, and Z are considered adjacent to island B, etc. for purposes of war starting.

If you're at war though everything should change. The range calculation should still be in effect, so Egypt won't invade by sea Britain unless they've expanded into the Iberian peninsula or the north coast of Europe even if they're at war.
