This would work for most states.  It might cause trouble when islands
are part of the eastern coast (i.e. Long Island in NY, Outer Banks in
NC) but other than those it would be fairly straight forward.

That said, I'll attach a script that converts the World Data Bank
files into gpx files which could probably be converted to osm files in
a fairly straight forward fashion.  The WDB files include coastlines,
islands, lakes, rivers and political boundaries.
