I'm starting to develop the main port facilities for my country that will deal with international cargo and I'm wondering whether to add shipping routes to other countries.
As I'm sure you're aware, OGF has an abundance of shipping/ferry routes (way more than OSM does). Are the lines between countries supposed to be for passenger ferries, like in OSM, or for both passenger and cargo? Because if they are exclusively passenger then I'm not sure why there are so many intercontinental ferry routes. My country is a small island nation so it would not have many long ferry routes, especially seeing as there is an airport instead.
