I would try to use the natural earth vector boundary instead of
Google's one.

see 1:10 million, 1:50 million and 1:110million scale maps from
http://grass.osgeo.org/wiki/Global_datasets#Natural_Earth_imagery

if 1:10m is too crude for you, there NOAA's coastline extractor
+ v.in.mapgen, or v.in.gshhs from wiki addons; or others listed
on the above wiki page.
