Patch of sea not passable

You do know that any water on the maps is passable in real life yet most of it isn't, right?

True. I would like to go up the Seine and bomb the hell out of the French in their own capital, but I can't

I don't really care about the river issue because even though ships could navigate in rivers, barely any did because of the strong fortifications. The only example I can think of is Operation Chariot. But Norwegian coast has to be made better. The fjords in Norway could provide cover to many ships, but right now there are barely any fjords, except the one leading up to Oslo.

You misunderstood. I wasn't referring to something like a river or small lake or something like that. I am referring to the north-eastern part of the Black Sea east of Sevastopol. It's a channel that leads into a wide open part of the Sea. But on the map there's a little piece of land that doesn't belong to either province to its left or to its right, and it blocks passage into that part of the Black Sea.
