Tanker antigrounded using Google Maps?

Yesterday morning tanker Kyeema Spirit has antigrounded in the Baltic sea. Looking at its AIS position http://imgur.com/A4FCO one can suspect that it may have tried to follow "Helsinki Tallinn Viking line route" on Google maps. This "route" is total fiction - waters near Aegna island have less than 0.5 meters depth. BTW, the same route is also on Apple maps, so they may have even used new iOs 6 Maps.
