The minimum breeze was in the teens. The sustained gusts were in the upper 20's (or more). It was calamity on the course with several capsizes at any given moment, a broken mast, a broken spin pole, chase boats everywhere, and a change of course that nobody saw and/or remembered by the time they clawed back to A - because of the chase boats required for assistance, a boat at the C gate couldn't be present to fly the Charlie flag - instead, the change course flag was flown (properly) from the Race Committee boat but I think it was a bit far away for us to hear the horn - I never heard it. Because the chase boats were so tied up, they left both A pins and offest marks in the water further leading to the confusion.
