Well, I'm just catching up and have watched thru Race 5. Going back to Don's "hooking" question, it looks to me that both skippers attempt to take the leeward side at the start and attempt to gain the overlap at the 1st mark so they can force the windward boat to luff, but neither are always successful. So in the 3rd race, Spithill "hooked" Barker at the 1st mark by forcing him to luff. But USA was penalized. What exactly was the infraction? I didn't even see how they paid their penalty, but they said something about a gybe (did they have to do a 360 and it was done that quickly? ... they didn't give up the lead at that point).
