Re the Hula. I cannot possibly comprehend that explaination of the Hula, but in simpler terms, there is a concept called a "hull speed" which is a maximum speed a specific hull can achieve without breaking out on a plane. It is a simple mathematical calculation, with part of the equation being the length of the waterline of the hull. The "hula" is designed (legally???) to extend the waterline of the boat, thereby increasing its theoretical maximum achievable speed.<br />In theory, it should only help in wind conditions that allow the boat to achieve terminal velocity (something above 15 kts or so, I'm guessing) and winds below that one would think that it would be somewhat of a drag (although I am not a designer)<br />The two races so far, IMO have shown the boats to be very equal in speed, both in light winds and calm seas, and strong winds and heavy seas.<br />This to me would indicate that the Hula has been pretty much much ado about nothing<br /><br />Race two, however, was spectacular. Alinghi was able to gain just the slightest advantage on the first upwind leg, and TeamNZ just powered by them on the second downwind leg. Whether they got favorable shifts of wind, or some puffs that Alinghi didn't get, or what the reason was, it was an impressive display.<br />Then Alinghi was able to cut just a few seconds off the lead per leg, but still rounded the 5th mark about 4 boatlengths ahead. And then the master went to work giving the student a lesson.<br /><br />Coutts forced Barker into some minor, but crucial, mistakes, was able to get in his windshadow, and power by him, finally forcing Team NZ out to the lay line maintaining a slight advantage, but forcing NZ into a position that they could not overcome. <br />Even Coutts almost made a slight mistake in the final jibe, and started to sail a higher course than necessary, but Butterworth was right there to remind him that he didn't need to. He had the advantage to the finish, and if he sailed a proper course, Team NZ could not overtake. And they didn't.<br /><br />Poor old Barker, skipper of NZ, was visibly shaken and upset at the end of the race, and it was clear that Coutts got to his psyche.<br /><br />He's got to think that they cannot win and make any mistakes at all, and the surest way to guarantee mistakes is to realize you cannot make any! It will be interesting to see if Barker can shake this one off, and come back in the next race. He's got an off day to think about it.<br /><br />But the boats are pretty much equal, and if the difference is sailing skill, I don't know if anyone in the world can beat Coutts and Butterworth.<br /><br />Amazing!
