Hello,

I'm doing quite often historical routings as a preparation for a race. 
It would be nice if it's possible to be able to show the result as a density map (heat map) on the nautical chart.
So it's easy to see which route is more likely to occur. 
Marintraffic has a similar function to show where most boats travel.
