Wally is from the87 America’s cup. Dick McCurdy and (I think it was Clay Oliver) noticed the wind Eddie’s down wind of Rotsnest island had a consistent period. Wally was the name of the program that did the math to rotary the polar diagram. With that information you would know the wind phase and the target boat speed delta to sail. So you are sailing to maximize your veg against the longer term average wind direction, not against the short term wind direction. You need to characterize the venue to understand the period and range of the breeze in your venue from the current wind direction. To learn more google ockam AND Wally. Nice presentation.
