Needs investigating what determines this, and similarly what determines minimum distance from seashore where you can still have ship waypoints. But i noticed that in some FEW places on the default maps you can have waypoints very close to shore. So I suspect it's something which has to do either with the water/coastline region spread on map_T or with map_c. Have you noticed that on all maps the water/coastline region is quite broad? Not sure why...
