Flat Earth Debunked: Lisa Blair

As of the time that I calculated (18th March 2017), A very brave Australian woman by the name of Lisa Blair was circumnavigating the antarctic continent all by herself in nothing but a sailboat. As of the date above, she was out at the coast of Argentina and was sailing at about 7.2 knots.

If the earth was the shape AND the same projection flat earthers claim it to be, it would take her MUCH longer to reach the area that she was at on the 18th of March. According to a YouTuber by the name of CoolHardLogic in his flat earth debunking video, the circumference of the flat earth in between Argentina and Antarctica all around the edge of the planet between the landmasses is about 103,700 kilometers. This gap between Antarctica and south america all around the edge in a circle is pretty much Lisa Blair's entire path for her journey.

On the 18th of March, she was 52% and 55 days through her journey on her way back to Perth Australia. 52% of 103,700 is 53,924 so she would've had to have covered 53,924 kilometers in only 55 days... but this is utterly impossible, as I mentioned that her average speed was about 7-8 knots. Let's be generous and say that she can remain a constant speed of 10 knots... unfortunately, it would take her about 121 days to do 53,924 kilometers instead of the TRUE 55 days at a much smaller distance and a slower speed.

In a nutshell, getting from Perth, Australia to the coast of Argentina in 55 days in a boat travelling 10 knots or less is utterly IMPOSSIBLE on an Azimuthal Equidistant Projection. It can only be explained on a round earth because her circle around Antarctica is smaller the closer to the south pole she is.
Here's her GPS log before failing her mission and having to go to cape town when her ship broke. (Unfortunately)



  1. Hey Callzter, I have a question: Is there a chance that the boat could go the other way, thus making the same distance which would be roughly only a quarter of the flat earth's circumference? You see what I mean?

    1. Here's something funny: She's actually continuing her trek, surprisingly. She'll be back in Australia in like another 55 days from now, maybe even less. We shall see!

    2. And to answer your question as if she decided to go clockwise around Antarctica rather than anti-clockwise... no it would still be impossible.

      Let's do some math.

      If South Africa is (lets be generous to the flat earth) 70% of the way around the edge, then if she went around the opposite direction then south africa would be 30% around the edge instead.

      30% of the original 103,700 kilometres circumference is 31,110. 10 knots is our generous speed for Lisa, it would still take 70 days...

      Wait... it did take her 70 days.
      Huh. I guess that WOULD work on a flat earth, but don't forget, she WOULD have to be in on the conspiracy AND she would have to go an extra 3 knots than her average.

      At her average of 7.2 knots, it would take her about 92 days. 22 days too long.

      So, if it were to work on the flat earth she would have to be LYING about which direction she was going AND also be going at an absurd constant speed of 10 knots. Pretty hard to keep constant on a sailboat, mind you!
