Yes, I'm not sure abo9ut teh Uk or Irish rules in details but in and
around sweden if for example you are a small vessel, some of the
international shipping rules are not applied for you ship. Such as the
need to carry day signals. Outside the water limits these rules don't
applie any more and you can be fined. The data in the swedish borders
comes form a EU database, not looked deeper into it.

Isn't the legal case same for everything? Hey officer my gps said the
was 90 here. Claming anything based on the map i think is wrong.

Who take resopsibilti to update any data, does these lines differ
really. The real line i then as well is not just 12nm outside the coast
but some kind of simplifactions of that 12 nm, also there are issues
when the line overlaps between two contries.

I personally would love OSM to have much more usefull data even at sea.
