While I dont go boating a full 12nm from shore, I am a keen boater and
my GPS navigation consists of a hacked navman using OSM maps, so while I
cant say either way in this particular case, I can say in my boating I
can say that my primary navigation method is with GPS and OSM data, only
falling back to paper map and compass as a backup.
