Blockading a province should lower the supply limit as if it were non-coastal

[Maovv]

There. Very logical and another strategic use for your navy.

Alternatively if it's your own province you are defending, the enemy must be blocking it to get greater supply limit.
Or you as the defender get to lower the supply limit by putting a fleet outside your besieged province.

I got this idea playing as England in the hundred years war, where it would be quite useful.


Another idea: Having an armed fort on both sides of a sea-crossing should make enemy navies unable to go through.
This mechanic could be expanded to peace-time possibly.

I'd actually say it should be much worse, perhaps removing the coastal bonus and reducing by, say, 10%. Blockades were damaging, moreso than they're given credit for in any pdox game. Especially towards the end of the game.

I agree, as far as I remember, blockades are what gave maritime nations with smaller armies *cough* England *cough*, an edge over other nations in war, they used it against Germany in WWI, France in the Napoleonic Wars, and probably more examples I cannot currently think of.
