Not sure if your are right about VOR and customized weather or routing information

"Well, in most ocean races they restrict you to receiving data that's free. So that means basically what you can use is US government data. The US government, because of our Constitution, says that once we paid for something as taxpayers, the government can't charge for it again. So the US government makes the global forecast system data, it's called GFS, available for free to everybody worldwide. So that's largely the data that you use during the race, because you can get that for free." Francois Gabart probably is using customized MaxSea pro version and no doubt these guys are not using auto routing
