In 2001, my company was a sponsor of the Whitbread race (then Volvo, now just the Ocean Race). We provided a computer for Quokka Sports to run a game where people could have their own virtual boat to race against the real boats and we provided the internet infrastructure for each port they stopped in. They sailed from Capetown to Melbourne on one leg, yacht races like the southern ocean because the winds are hihest there, so it is basically a race around Antarctica.
Several people in my department went to each port before they got there to set up, operate, when they left, tear down and ship to next port. They sent me pics at the dock and in the boats.
Sailboats have a hull speed, they can only go so fast (I tried to get a sailboat to go faster than hull speed, it dug the nose in and turned, indeed impossible). The computer game showed their location continuously. The sailboat speed, published distance, and time the trip took all matched perfectly. On any FE map I have seen, the distance is thousands of miles longer and the sailboats would have to go 90 mph to make it.
I conclude that RE distance is accurate, FE is impossible. FEs, where is my mistake?
