Simple,

You're getting worst than Nutsy. "America's Cuppers" sail downwind from
lay line to Layline, Gybing several times in so doing, If it was
faster, why does the windward boat cover the Lee boat sailing for the
Layline. Using your logic ,the trailing boat would gain the lead and
with no trouble passing by going straight downwind

Boy, what a downwind leg it would be between you and CM!!! Oh Yeah!!!!

P/S Neal I have many, many tapes of America Cupper downwind, Even going
back to the 12 Meters. Everyone with Gybing downwind. I could let you
have one if it would help you
