The Ocean Globe yacht race, currently underway, is a round the world race run under retro rules including no electronic navigation. Sextants and celestial nav are used instead. The fleet is in the Indian Ocean now. For safety, the race organisers require the yachts to stay north of some virtual rounding marks, to reduce the risk of meeting ice. Finding a virtual lat/long position thousands of miles SW of Australia must be a challenge if days roll by with no break in the cloud.
The yachts have on board gps trackers, again for safety, that the crews cannot access. But shore teams, and the general public, can watch progress. In the attached screenshot, the orange dot is one of the virtual rounding marks. Some yachts almost missed it and discovered their error in time to correct course. One missed it and hasn't realised.
