I believe the British had artillery support from their ships at the battle of Bunker Hill during the American Revolution, so I guess it must at least have been accurate enough to have a reasonable chance of landing somewhere near the enemy army and not their own.

But the accuracy doesn't matter from the point of view of modding, all that would matter would be the ability to call in an attack from outside the map. It seems to me this is the simplest way of handling naval bombardment; the alternatives would be to model the ships on the battle map itself (which sounds like a lot of work for not much reward), or not include it at all (which is possible, but seems unlikely to me).
