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.

Red Eye 2026 - Georgian Bay

Welcome to the sensational scenic Georgian Bay of northern Lake Huron, the first area of the Great Lakes to be visited by Europeans in 1615, so former SOLer A2R informed us when he designed this geometrically tortuous course of 317nm criss-cross through its island maze. Originally known as Lake Manitoulin, in 1822 the bay was renamed after King George IV after his succession to the throne. This time we’ll take the very flashy Fareast 31R, which hopefully should keep you wide awake!

Tall Ships 2026 - Stavanger to Aalborg


Welcome to the fourth of four virtual Tall Ships Races in European waters which are concurrently being organized in-real-life by Sail Training International . This fourth race is from Stavanger in Norway into the Skaggerak to a finish off Denmark’s Aalborg and perhaps an Aquavit to toast the adventure afterwards – a final circa 250nm in Sailonline’s classic Clipper 240.
NOTE: Starts and Finishes in tall ships racing are always offshore to avoid conflict with shipping and shipping lanes; online and real-life may not match exactly.

Chinook Salmon - Canada to Andreanovs


A year after spawning in the upper reaches of the rivers of British Columbia, Chinook Salmon develop the age-old urge, so familiar to SOLers, to go to sea, heading for different parts of the northern Pacific Ocean. This race catches up with a particular school with an instinctive memory for the Andreanov Islands far west on the Aleutian Islands chain, as they depart the Salian Sea between Vancouver Island and the San Juans. It’s 2200nm and we’re taking the 60ft Trimaran, in the hope we can keep up!
