Dear Florian,

The Region of Aysén del General Carlos Ibañez del Campo in the Chilean
Patagonia is composed by hundreds of Islands and fjords, and each one of
them is being included inside the region boundaries (
http://osm.org/go/JdvTx--).

It seams reasonable to surround the pieces of land under some local
government jurisdiction if the sea around them is under some central or
federal government jurisdiction (that is why the sea boundaries only include
the Chile relation). Regional and municipal jurisdictions only reach to the
coastlines, from there to the territorial, contiguous and exclusive economic
zone sea boundary lines the navy is in charge of providing security and
enforce the law.

Some examples of coastline boundaries that I found in Europe:

http://osm.org/go/eq...@o-

If it is not the "right" way to do it or there is a better way to do it,
please let me know.

Regards,
