For the upcoming Louis Vuitton Cup, which begins on October 1, there are nine challengers, three of them from the US. The Seattle Yacht Club, the New York Yacht Club, and the Golden Gate Yacht Club will battle each other and five European contenders for the right to challenge. The other nations in the lineup are Italy, with two separate would-be challengers, Britain, Switzerland, France, and Sweden with one contender each.
Now Bartarelli's challenge is considered to be one of the strongest of the nine contenders. Coutts, the master helmsmen who has won the last two America's Cup contests, is also an engineer, and he was closely involved with the Kiwi design team leading up to the 2000 defense. With his technical bent, he would have understood and surely remembered many of the features that made NZL 60 a super boat. That invaluable knowledge made its way with him to the Swiss camp and would have been a splendid starting point for Bartarelli's 11-person design team, led by Dutch naval architect Rolf Vrolijk.
Laurie Davidson, the New Zealander who played a major role in the Kiwi victories of 1995 (when they took the Cup in San Diego) and 2000 (when they defended it with such resounding superiority in both design and boat handling), was hired by Seattle tycoon Craig McCaw to lead the design team for his OneWorld Challenge. Several Team New Zealand crewmembers also made the switch to OneWorld with Davidson.
Davidson's influence has been pervasive in America's Cup design offices. After the 1995 victory of NZL 32, which he designed in collaboration with Californian Doug Peterson (who later switched to Italy's Prada syndicate), there was a scramble to emulate or improve upon that boat's slippery hull shape. Peterson's efforts were put into the magnificent Luna Rossa designs that took Prada to the 2000 Cup finals against Davidson's NZL 60. Other design teams, making educated guesses if they could not get hard numbers, came up with boats that were obviously of the same family as NZL 32.
The intensity and drama of the upcoming Louis Vuitton Challenger Races for the America's Cup might only be defused if a challenger happens to come up with a breakthrough boat, and this is highly unlikely. Under the America's Cup Class measurement rule, long, narrow, and heavy boats have proven to be fast. With the existing trade-off between the speed-enhancing factors of sail area and length opposing the speed deterrent of weight, America's Cup designers have long known that a design at or near the top weight limit of 55,000 pounds can then have sufficient length and sail area to produce a competitive boat.
There is another slim possibility for design deviation within the current crop of International America's Cup Class boats. Deep draft virtually always improves upwind performance. However, under the America's Cup rule, any draft greater than four meters (13.12 feet) is multiplied by four and added to the measured length of the boat. This is a stiff penalty, but perhaps one worth considering, and it could be that the Farr boats are trying a combination of more draft and lighter weight. When sailing to windward, less sail area makes very little speed difference, and in heavy air it might even be an advantage. The mainsail and jib luffs actually remain the same length and the reduction in sail is taken off the foot of the main or the length of the foretriangle. Although this reduction would have little effect upwind, it would mean a lot less sail area downwind as foretriangle length also governs the width of the spinnakers. So it would be a tossup whether the lighter displacement could make up for the smaller sail plan. In my view, it probably would not in light air, but the combination could be very quick in strong winds. Nonetheless, a deeper keel would not pay downwind in any condition.
Hull structures are as light as they can be made under the rule, and the only place where significant weight can be saved is in the lead ballast that lives at the bottom of these keels, four meters below the surface. Reducing weight here also reduces stability in the computer, but if the sail area is also less, then stability under sail would be comparable to that of the other boats.
Farr took a step in this direction with the boats he designed for the New York Yacht Club during the 2000 America's Cup. But that campaign faltered due to lack of time and then stumbled to its knees when Young America nearly broke in two during a race and was saved from sinking only by the Herculean efforts of the crew and the Italian support boats that happened to be nearby. The Young America boats were purchased by the Prada organization after the 2000 event and reports from Italy some months later indicated that the Farr boats were a shade faster than Prada's own boats that had won the Louis Vuitton Cup and faced the New Zealanders in the finals.
The guessing game regarding design approaches to the 2002-2003 America's Cup will go on for another month, and then on October 1, the opening round of the Louis Vuitton series will begin on the Harauki Gulf and all the speculation will be replaced by stark reality.
