1.0 -- KATHARSIS II MAKES EXTRAORDINARY CLAIM in 2018.
Here it is November of 2019 as I post this and yet an apparent circumnavigation along the lines I've been thinking ought to be done-- was completed around April 2018, a year and a half ago-- by a crew of eight on a sailboat called KATHARASIS II. Here is their route-- a little further south of 60S.
2.0-- NEW INVESTIGATION of CLAIM OF 15,000 MILE CIRCUMFERENCE at 65S
I'm going to open up an investigation into this claim, of course-- I must-- if only to continue this blog's point and purpose. The first problem I have here is that the claim KATHARSIS II is making-- that they completed the circumnavigation in about 3 months and that they travelled about 15,000 miles-- would definitively prove that Earth is indeed a spinning ball and not a pizza shaped flat disc-- at least by my own rules here in this blog. I'll leave aside considerations of a toroidal field in 4-D hyperspace for now. Here's a screenshot of their claim...
2.1-- Would any such claim satisfy me one way or another?
How would I judge the validity of the claim? My answer at the moment is that the test run would have to be repeatable-- as all experiments in science. And the test runs would have to reveal more technical data than is revealed in the online sources for the claims by KATHARSIS II.
3.0-- OTHER CLAIMANTS of CIRCUMFERENCE of 15,000 MI.
They claim that "no sailor in history has managed to circumnavigate Antarctica so close to the continent so fast". I would think that they might have mentioned the VENDEE RACES and another Australia based race organization as close seconds but they do not. See Vendee in my index below-- a race series that I've determined to be a possible hoax.
4.0-- OTHER INVESTIGATORS I'LL SUMMARIZE HERE on this point about the circumference.
Matt Boyland, Chippy.

8.0-- SIZE OF THE SAILING YACHT PROBLEMS
8.1 The yacht looks too small and frail for this type of voyage-- to me.
8.2 The sailing yacht was subject to no-wind conditions and could not reliably do the trip.
8.3 The diary of the voyage indicates they were overturned and lost all the crew in the water at one point-- unbelievable.
9.0 MAP PROJECTION COMMENTARY
9.2 Why go south of 60S?
9.3 How were they legally able to south of 60S?
10.0 Where did they get the idea to do this journey? (or fake it?) From my blog here? It almost seems to be so.
10.1 "Around the Ice" seems to be a direct attack on the idea that Earth is flat and that the ice is a wall surrounding Earth. The expressions on the faces of the voyagers seem to be looking at me, personally, in a weird sort of way-- telling me that my blog here is pointless-- that they've proven the Earth is a flying ball in space because they sailed "around the ice." Special looks from these three sailors concern me... These three seem to be saying-- "What can you do now, Rick?... Nothing. B
11.0 The LOGO seems to be AMBIVALENT and an "in-your-face" affront to flat-earth thinkers.
Notice the perimeter of the logo-- almost a copy of the UN logo with the leaves representing the "ice wall". Here too, despite our seeing an "island" of Antarctica, it's surrounded by a possible symbolic "ice wall". A more generous interpretation would be "ocean waves". Is the ambivalence premeditated and intentional?
12.0 NAVIGATION screen shots indicate GPS positioning but what about NAVIGATION by STARS?
12.1 How would a trip around Antarctica be monitered by the crew, or by a third party? How were the trips monitered by the Vendee Races? How are ships tracked in the Antarctic region that go to the stations?
12.2 Is anyone using star charts anymore? Sextants?
12.3 How is distance measured in the water?
12.4 How can this trip by Katharsis II be INDEPENDENTLY verified? Is an award by a sailing organization enough? Should we verify the existence and legitimacy of the sailing organization?
12.5 Is this a repeatable trip-- on a more comfortable yacht? Would anyone be interested in doing it again... and again? Katharsis II says its the first to do it below 60S-- yet Antarctic research stations have been there for decades. My blog, here, proposed a round-Antarctica trip by stopping at each station. Is that possible?
13.0 My post to the KATHARSIS II website will attempt to solicit more data.
14.0 CONFLICTING centroid map routes raise PROBLEMS--
Discussion: I did not gather the source links-- just screen grabs. Will update with links to source.
15.0 GREEN SCREEN?
Discussion: The photo below looks like a green screened pose. There are no water droplets on the subject. The subject is not wearing gloves. Water drops and spray not apparent on any part of the boat. Gray sky would project a dimmer light on subject. 
16.0 YACHTING WORLD covers KATHARSIS II Voyage in a shallow way. [Yachting World]
Discussion: One would think that a magazine that specializes in sailing would cover the Katharsis II trip in a somewhat technical manner, akin to Scientific American. Nope. Their coverage was shallow.
17.0 Easier route at 60S rather than Antarctica circumnavigation.
https://rickpotvinflatearth.blogspot.com/2017/03/easier-route-at-60s-rather-than.html17.1 Circumnavigation below 60S should be less than 12,000 mi on a globe.
The 60th parallel south is a circle of latitude that is 60 degrees south of the Earth's equatorial plane. No land lies on the parallel — it crosses nothing but ocean.
The circumference of a globe at 0 should be about 40,000 km, they say. What is that in miles?

At 0 latitude, we have 24,901 miles.
At 60 lat., we have 12,482 miles.
17.2 REVIEW the RELEVENT DETAILS of the VENDEE RACE
Discussion: I covered the Vendee Races in some detail a few years ago. See Index below. I'll summarize them here for the purpose of this current post about Katharsis II here, soon.
Presentation - Vendée Globe 2016-2017
www.vendeeglobe.org/en/presentation
The Vendée Globe is still the only non-stop solo round the world race without ... to make a compromise between the shortest route, which is the furthest south, ...
17.3 Isn't travel south of 60S illegal according to Antarctica Treaty?
18.0 Are WINDSPEEDS are too high for sailboats below 60S?Discussion: 60 degrees south is also a natural dividing line where the ocean and air currents circle the planet without any land to disrupt the flow.
19.0 FLAT EARTH SOCIETY POSTS from 2013 examined many of the issues covered here. I only recently either discovered or re-discovered that series of posts.
20.0 KATHARSIS II voyaged to ROSS SEA in 2015.
Discussion: See short video referred by anonymous commenter. The front of the sailboat seems to be hitting ice floes. How is this possible in a sailboat? I looked up the type of boat. It's manufactured by OYSTER YACHTS in England. They're out of business now so I'm unable to ask them if they recommend against sailing through ice. I could talk to other OYSTER YACHT owners and get their opinion. It doesn't seem likely, to me, that a crew would sail around or even to Antarctica in a yacht of this relatively small size compared to bigger ships that made the trip through history.
Discussion : It seems to me that if a "sailboat" that runs on "sails" and "wind" is sitting in what appears to be a bay surrounded by ICE -- that it MUST have engines to get going again. This is easy enough to double check since the sailboat was manufactured by OYSTER YACHTS of Southampton, England.
22.0 A "DAY BY DAY" CAPTAIN's LOG of such a voyage would not consist simply of candid shots of hugs, waves and t-shirts, and fabulous views.
Discussion: Were there no crises that warrented photos? Where are the date stamps? In the collection of photos below at the official website, https://antarcticcircle60s.pl/en/media-2/, we see no date and time stamps. An actual cruise like this should have date and time stamps on photos, no?
