Andres:  We get the country boundary database from Generic Mapping 
Tools, so unless they fix it, we won't have a fix.  If you can suggest a 
better database that does not have this problem, I can try to 
incorporate it.

I guess it is possible is also possible that this is intentional - and 
the border does extend into the sea.
