At first the Holy Grail for this America’s Cup was foiling. Emirates Team New Zealand figured out how to foil off the wind and changed the game for everyone. The next Holy Grail (if there can be two Holy Grails!) is foiling UPWIND. And Oracle Team USA looks like it might have unlocked that secret (though it’s hard to know if they are using elevators or any other flap systems that aren’t allowed by the AC72 design rules).
If Oracle has sorted out upwind foiling, that’s going to put a lot of pressure on ETNZ (or Luna Rossa if they somehow happen to win the LV Cup by breakdown default). Though my guess is that ETNZ is close on upwind foiling (if they are not already there and keeping it under wraps).
An intriguing and interesting development…
