Every boat needs a helmsman and a main trimmer like Oracle. You can see Artemis crossing and coming off the foils, and Oracle slamming on the brakes while coming up as the boom comes across.
Closing at more than 40 knots, and no time to trim, duck or do anything except the right thing obviously gets interesting fast. We think this is scary at eight knots. Who was that said “…watching a sailboat race is like watching paint dry.”?
