Another excellent GeoShifter review of 20th C. circumnavigations listed on Wikipedia applied to both the globe and the flat earth map for a very quick an interesting overview. These are not quite the Antarctica level circumnavigations I need to verify a 60,000 mile flat earth rim vs. a 15,000 mile spherical perimeter to an Antarctic island-- but they're close. Unfortunately they're all well north of 60 deg. South Latitude for most of the journey-- many not even going south of the equator. The Vendee yaught races are supposed to be close to the 60S latitude line but there are problems in verifying anything related to those as well. For now, consider the following journeys around the world by water.
