Americas Cup Observations

| 0 komentar |
Its clear that the AC/72 boats represent the most significant advances in yacht racing in a generation. While small boats like the Moth have been foiling for years and other large multihulls have been using foils that are adjustable for cant and rake, the 72s are arguably the first to combine foils, wing masts and sophisticated foil control systems in in a truly competitive package. It is also important to note that there were no significant gear failures during the regatta. That is a testament to the highly developed design, engineering and testing programs of both teams. I think this bodes well for the future of the Cup competition. Once again, I have to confess that before the event I was among those who felt that this event could very well be a dismal failure. After witnessing the spectacular racing I changed my mind in this regard.

I watched every minute of the racing on TV and think it was extremely well presented. Journeyman sports announcer Todd Harris did good job in spite of having no real yacht racing experience. Sure, he made a few goofy comments but he also frequently acknowledged his lack of experience in the sport and didnt try to come across as an expert. I thought that was a refreshing departure from previous AC announcers. NBC relied on a cast of true sailing experts to deliver insightful commentary and I thought they all combined to deliver a quality sporting product.

What about the crews? Without access to the inner workings of each team we can only speculate on what occurred within them as the regatta progressed, but the indications are that the American team had not spent nearly as many hours on the water, in the boat they would race in the finals, as the Kiwis did. This became glaringly apparent when a Team Oracle crewman fell overboard before the start of the first race. Another interesting facet of the American team was the body language of two key members of their afterguard, John Kostecki and Tom Slingsby. We dont know what that interpersonal relationship was like but it was obvious that things improved when Kostecki was replaced by Ben Ainsley. This is not to take anything away from Kostecki as he has had  a long and illustrious career as a professional sailor. But sometimes personalities dont mesh regardless of the skills and talents of the individuals and perhaps thats all there was to it. In any case, the shift from Kostecki to Ainsley made a significant difference and in my opinion was a key factor in Oracles eventual victory.

It was compelling personal drama to see the juxtaposition of confidence in the two crews as Oracle began racking up wins against the Kiwis who came within a few puffs of wind of winning the event when race 13 was abandoned with the ENZ ahead with less than a mile to the finish line. When that race was re-sailed later in the day, the Americans began their improbable march to 9 points and the Cup. As the Kiwis suffered loss after loss their confidence was replaced first by concern, then worry and finally desperation. At the end of the event the strain and despair were evident on the faces of the ENZ team, especially that of Dean Barker, whose helmsmanship could not be faulted except on the starting line where he was frequently bested by Spithill. The Kiwis made few tactical errors and only one glaring boathandling error when they nearly capsized.

It was also interesting to see how the Americans continued to improve daily while the Kiwis seemed to remain constant in terms of boatspeed. I can only attribute that to the fact that Oracle was the faster boat and it took several races for the Americans to learn how to sail it to its optimum potential, while the Kiwis had the slower boat and couldnt get much more out of her.

In the aftermath of the event, Team Oracle accepted the challenge from an Australian group for the next Americas Cup competition. We dont know what kind of boats that regatta will be sailed in, but given the spectacular racing we witnessed in AC XXXIV, Im looking forward to some incredible technological advances and exciting racing in the event to come.

Americas Cup Surprises Abound

1. Oracle looked sloppy when a crewman fell overboard before the first start. No surprise there. Its not uncommon for the defender to be rusty early in the series. Without a competitive qualification series against serious competition, defenders often fail to develop the competitive reflexes and instincts that challengers which have struggled through an elimination series have developed.
2. TNZ showed up with their A game. Oracle did not.
3. The word around the yacht club bars was that TNZ had the faster boat. It sure looked that way in the first three races. But maybe thats not so. Oracle showed flashes of boatspeed, but was foiled by poor boat handling and tactical errors in the first three races. They showed something different in race four.
4. A huge surprise was the series of tactical errors Oracle made in the early going. On the other hand it was beautiful to see how they learned from the early races, adapted and found a way to win in race four.
5. Another surprise was how both crews handled the 72s as if they were dinghies. They both showed that they can create opportunities to pass. This is probably the biggest surprise of the event.
6. Conventional wisdom states that the faster boat will win. Why is that? Well, first of all its incredibly demoralizing to be on a boat that you know doesnt have the straight line performance of the competition. On the other hand, its just as empowering to know that your boat is faster than the competition. It gives you the confidence to sail more aggressively, take more risks for greater rewards.
7. It is also true that, all else being equal, he who makes the fewest mistakes wins. Oracles early errors played a large part in handing three victories to TNZ. By the same token, TNZ had a few less than stellar moments and let race four get away from them.
8. Do not underestimate Kostecki. One thing you can be sure of is that the crew of Oracle learned a lot in the first four races and, more than anyone else, John Kostecki took the measure of TNZ. It was not a fluke that Oracle won race four.
9. With the 24 knot limit on windspeed, these boats will probably survive the entire series. Still, they are experiencing apparent winds of over forty knots on the upwind legs. Im expecting more carnage before this event is over.
10. Contrary to popular opinion, including that of yours truly, this is turning into an exciting event and I am looking forward to tomorrows racing!

Americas Cup Lessons Learned

| 0 komentar |
Apologies for the long hiatus from this blog. Its been a very busy six weeks since my last post, with several projects completed on Finisterra. But first we need to consider the AC regatta and lessons we can take from the racing and the boats themselves, and what this incredible event might mean for the future of the competition.

The boats:

1. It appears that Team Oracle really did have the better boat. I had thought that the bows might be too fine, lacking sufficient buoyancy to support the wing mast. But the designers and crew were able to keep the boat on its feet throughout the event. The Kiwis chose another route with fuller, more buoyant bows. Perhaps in a bit more swell that would have paid off, but it is clear that the Yanks had the faster boat for the conditions they encountered. This is an indication that Team Oracles designers had a better feel for the expected conditions on the bay and did a better job of targeting their boat for them, while the Kiwis opted for perhaps more of a safety margin in their bows and paid the price with more weight and windage up forward. This would cost them speed especially on the upwind legs.

2. Deck layouts for both boats showed significant differences. The most striking of which were the airfoils mounted on the aft cross beam of ENZ. There was a price to pay for them in terms of weight and drag and I think its doubtful that they did enough to smooth out the wind vortices swirling off the boat to offset the negative factors. The Kiwis seemed to have a more efficient winch layout, but I noticed in the later races there were times when grinders werent in the cockpit but grinding from a position on the trampoline instead. This was an indication to me that the crew was getting a bit rattled as they racked up loss after loss.

3. Much has been said about the fact that the tactician aboard Oracle had to grind winches on each tack or jibe while his counterpart on ENZ was able to keep his head out of the boat more and focus exclusively on tactics and strategy. This was more than offset by the addition of a strategist aboard Oracle. The early races showed that communication between tactician, strategist and helmsman would be crucial and it looked like ENZ had the better operational arrangement. However, once Ben Ainsley replaced John Kostecki those lines of communication improved drastically and it was beautiful to see how well Oracles afterguard worked together, and this was a key factor in Oracles string of victories.

4. There were other design features in the boats that probably made a difference. For example the helms on Oracle were angled inward a few degrees. This probably resulted in better ergonomics for the helmsman than the directly forward facing helms aboard ENZ.

5. As far as I could tell, the daggerboards were roughly the same but of course I dont know what the actual foil sections were. Another area of vital importance is the board control systems. We dont really know what the differences were and which worked best at raising and lowering them. Nor do we know which system worked best for adjusting cant and rake of the boards. Of course we can infer that Oracles worked better since they won but it would be fascinating to see side-by-side comparisons of these systems.

Ill write more about the actual racing in a later post.
