USA Aether A2 said @ 2010-03-21 18:41:46:
If a boat has overstood the lay line or a wind shift has caused a boat to find itself beyond said line, should not that boat have to lose ground to return to the center of the course at some point?

If a skipper has the option of waiting until after passing the finish line extended to make this correction, the wind condition on the line may be at odds with what may have existed earlier up the course.

This then would present two unequal choices and offer in some cases an actual unfair edge.
-----------------------------

In the scenario you describe above, the possibility of crossing the finish line from behind can only provide a minimal advantage.

Indeed, if the wind dictates to wait for the tack or gybe until the last moment, then it also means that the fastest way to finish is to cross the line as close as possible to one of its extremities. Anything else is slowier.

The only difference is then one tack very close to the line (see attached picture). This is negligible. The perf loss due to the additional tack does not even last for the whole distance because you should cross the line immediately after the tack.

PS: In the attached picture, the differences between both options have been much exagerated for the sake of clarity. Both options should in fact cross much closer to the extremity.

Thank you for this detailed explanation which clarifies the matter.

I suppose that without right of way interaction the gravity of being outside of the lay line does not carry as much weight in this virtual environment.

Current Races:

New Ice Age 2026 - Scott Base to Neumayer Station


To complete our DN circumnavigation of Antarctica and our 4-race ice-boat marathon series, we continue clockwise, now departing from Scott Base back to Neumayer Station. It’s about 3500nm back as well, which, as said if there’s wind at all, should, well-wrapped in your DN-cockpits, not take you much more than five days. And remember: charts down here are unreliable – what is land and what is ice?!

Cross the Convergence 2026 - Tenerife to Fernando de Noronha


The sixth race of our series of ocean voyages across the World’s convergence zones takes us back up the Atlantic to Tenerife, from whence we will depart on a classic transatlantic passage to Brazil’s Fernando de Noronha. It’s 2150nm as the albatross flies, but you will undoubtedly have to take some and sometimes sudden detours to get your Volvo 70v4 through the doldrums stretching across your path from the Amazon to the Niger.
