@gabrielbezerra It's much more low-tech than that :P... I draw over a map by hand. The hand drawn route is very close to our actual sail, but not exact, evidently.
We used to use a live map for that, but adding way points on it to make a detailed route was just a pain in the ass (https://100r.co/live/ as you can see it's messy AF).
@rek Oh, I see. Perhaps AIS trackers like MarineTraffic or VesselFinder could provide more accurate data for the live map?
In any case, the hand drawn maps look great. Thank you for sharing them.
I wish you much success in your journey.
Travel safely!
