Yes, I checked the official site (after running a regatta today), and all of today's racing is postponed until tomorrow (they never got 6 knots, apparently).

I think the best race so far was the light air race between FRA and GBR. A nail-biter all the way through, as they had to try to foil, or sail fast without foiling until they found a puff. The race ended with a P/S cross at the finish line.

As much as I loathe the thought of ever going back to monoslugs, I do understand the concept that match racing is best with boats that sail at around the same speed, all over the course. It's hard to stay in contact and force engagement and rules infractions when the first boat to round the weather mark (or get onto foils) takes off.
