Looks like Oracle's strategy is to foil upwind as much as possible. They where doing 33.5kts upwind just now, insane.
The bigger jib today really helped, but now, between races, they are taking it off for a smaller jib. The wind is building a little but if the bigger jib is working, helping them foil upwind, why change it??
Is the ebb difference of what, 2kts, going to increase their apparent wind that much? The forecast true wind is supposed to go from 17 to 21...? That's 4kts, plus the ebb of 2, total of 6 more knots of apparent wind, I guess that's enough to justify the smaller jib.
