The sea would be rendered transparent rather than blue. There might need to be some manual tweaking of the coastline, since Google and OSM have different opinions on where the coastline is (so Google's coastline is revealed in small spots, if the sea is transparent).

Could mapnik not just be instructed to put a thick blue border around
the sea before the transparent part? Or possibly just define a polygon
in the sea that is both the end of the sea rendering, and the extent of
what is to be rendered in mapnik. That way, it can easily be re-used if
things are updated.
