ok, let's say i wanted to use this as a basis for drawing the national
boundary for a country. i appreciate that part of the border will be
more than 12nm away from the coast (depending on the depth of the
ocean floor, yes?), but it's a good start

does some enterprising coder want to come up with a way of
automagically drawing the border at a 12nm offset to the coastline?
anywhere that the border is different, i would be happy to edit it
manually, if a large part of it was being done by programmatic means
