I'm using Google Maps API to add a map to my website that controls the route of a sailor. The route points are added on the fly with javascript and they are not quite detailed, so sometimes I get a line crossing over land.

Is it possible to add points to a Polyline and automatically avoid passing through land?

Short answer: no. There is no way to know whether a point is on land or above water with Google Maps API. See my answer here: http://stackoverflow.com/a/22906947/1238965 – MrUpsidown Apr 28 '14 at 15:47
