I think use of legs for grinding used not to be allowed.
That was a smart move by Ainslie to luff the Kiwi boat up above the starting mark, though I don't think he could have foreseen their pitch-poling like that.
A shame the GB rig broke when it did and that they couldn't do better. I was rather hoping that with the Kiwis having chosen the GB boat as their competitor on the basis that there were light winds due, that the increased winds would have reversed things, but, alas, it was not to be.
Time to regroup, assemble another £20million (or whatever it is) and prepare for the next one.
