The photo looks like it was boat #6 that broke the mast. I'm pretty sure it was boat #8 that was flipped to fix the spin halyard block. It was the race that Ding probably got redress for on Wednesday. Can you check if it was #8 or #6?
Boat #6 David
We had more than one of the sheave issues, and boats were regularly being turned over for various reasons.
Here is what I have found so far in the forensics of the pictures. I have many pictures of the spreader square on the end of day 3.
Day 4 the team on boat #6 in the previous race was Jake. I have a picture of the spreader in the compromised position. There was another race before (A fleet) that I have nothing on yet, so the spreader was raced in the compromised position for at least 2 races. Remember in all the hoists the spin was to port.
Tad, Is there a way I can attach the picture larger than 100K. Send me some magic . . .
