Blockade 2 tiles away = get killed

[Celevin]

I find cities don't bombard for much damage anyway, so it's not really too big of a problem. I'd be more worried about siege engine fire.

A naval unit does not represent a single ship, except perhaps an aircraft carrier.


A single naval unit is sufficient to blockade. You don't have to literally stop every tile or every other tile.

No, CAN you do it out of range from the coast, but with ships close together instead of 2 tiles off the city? Not if it is a good idea.
