How do I establish a sea route?

[Penguin Glory]

Hey all, I was trying to trade with an AI on another continent, but it says I need to establish a sea route. How do I do this?

Thanks!

You need harbors at each end of the sea route.

If it's only foreign cities on the other continent, you're outta luck until the AI builds a harbor.

Just having two port cities isn't enough...I had a game where a port city on the FAR side of a continent didn't create a trade route, even though you could travel by sea between both cities. Apparently there's some rule about the directness of the route. Anyone?

There's no rule about the directness. The route must have been broken in some way, Ie by an AI's territory who one of you were at war with.
Remember you need to have researched Astronomy to traverse sea, and navigation to traverse ocean.

Note: You need to be able to see a clear route before you can actually trade via it. If you can't see that part of the map, then it's a no go.

Thanks for the replies!

Don't forget, you need Astronomy to trade across sea squares, and Navigation/Magnetism to trade across ocean squares.

Since we are talking about trade, I thought it was kinda clear

You musta edited that it with a magical-no-edit-tag editor, cuz I didn't see it!

Rule #1 to trade. Don't ever, EVER rely on a sea route without Astronomy if your Reputation is at stake. You're guarenteed to have a barbarian galley sailing along that route eventually..

I am very much annoyed : although I got harbors on both continents, and navigation and astronomy as techs, and no black squares hiding the sea between my harbors, I still do not have any sea route established between my cities abroad and the motherland continent... Do I have to specify my will somewhere, or is it supposed to establish automatically ?

From my limited knowledge, i tried to make sure the two cities on the edge of each continent were facing each other, and a trade route was established as soon as i built a harbour on my side, as the rival civ had one too.

It says there must be a harbour in both cities of the same ocean, so maybe building a harbour on the other side of your continent means its on a different ocean., and therefore wont count.

Could you post a screenshot of some sort?

Perhaps the civ you want to trade with is disconnected?

Or there's a trade embargo?
