I think teams with prior international campaign/olympic experience will adapt to the boat and their experience will show through. Just my opinion.
REALLY!
This has been the standard US position.... take an All American college 420 sailor and coach em up....in 49ners or Cats or windsurfers etc. I think it is just wrong.
Prior international experience is also over rated.. Bundy tried a short go at helming the 49ner when the T was dropped.. did not work. The number of sailors who medal in two very different classes are few and far between.
In fact, I will argue that the AC 45 experience tends to suggest that the instincts to race the high performance boats must be developed from an early age. Terry Hutchinson is a great world class match racer and sailor but he was replaced with a 49ner helm. Terry just could not make up the countless hours on the helm of a boat that is super high performance.
I am going to go with Gladwalls theory that mastery, is at its core, about hours doing the exact task.
The idea that a great sailor can change disciplines and win a gold is not a sure thing....
