Was Mark Slats the 1st Golden Globe Racer to Circumnavigate under sail?
In December 2018, Mark Slats was the first Golden Globe Race 2018 sailor to cross his outbound track and cross 360 degrees of longitude. Does that mean he circumnavigated the globe in the GGR 2018? This video looks at the definition of a sailing circumnavigation and identifies several sailing voyages that are commonly referred to a circumnavigations that were not. Captain Linus Wilson discusses the famous trips by Laura Dekker, Jessica Watson, and Lin and Larry Pardey in Seraffyn that did or did not meet the definition of a circumnavigation. The hardest part of the definition to satisfy is the antipode rule that you must pass between points on the opposite sides of the earth.
A circumnavigation of the Earth must:
1. start and finish at the same point
2. travel in one general direction
3. reach two antipodes
4. cross the equator
5. cross all longitudes
6. exceed the circumference of the earth at the equator of 21,600nm
The sailing races the GGR and Vendee Globe may often produce finishers who do not circumnavigate because the course does not require that they cross antipode pairs. The easiest antipode to intersect lie just north of the southern tip of New Zealand or just north of Les Sables D’Olonne, France. The racers have to nearly finish the race before they have a chance of satisfying the antipode rule.
