Thank you Bill, I should have thought to look there. Your definition does the job although the average sailor may struggle with it. I then found, on adventurestats.com
A true circumnavigation of the Earth (around the world) must:
- Start and finish at the same point, traveling in one general direction
- Reach two antipodes*
If they just added a liitle waypoint at Fastnet Rock on the way out and ensured that they went south of 52S 170E that would fix it.
