It could be a game-breaker. Oracle Team USA showed off their ability to foil upwind yesterday as skipper Jimmy Spithill taunted Team New Zealand for "running away".

A day that started with so much promise with another great start by skipper Dean Barker that slingshot the AC72 several hundred metres into the lead after mark 1. By the time the AC72 had reached the top of the course again a small gear issue stopped it in it's tracks allowing Luna Rossa to sail up from 400 metres behind and into the lead to take a valuable race point.

The moment the AC72 suffers any damage the Emirates Team New Zealand shore crew jump straight into action to prepare for repairs before the boat or parts have even hit the dock, and they don't stop working throughout the night until the boat is fully prepared for racing the next day.

Brad Butterworth and the bulk of the crew from the Alinghi America's Cup syndicate gathered around a television screen yesterday on Hamilton Island.

It was all go in race one of the Louis Vuitton finals. After a delayed start because of wind at the upper levels, the race was all but over when Luna Rossa had gear damage to their board system by the first mark. At mark 3 were some of the most dramatic pictures of the regatta yet. On the bear away the bows on the AC72 dug in and bought the boat almost to a standstill sending two of the crew overboard. The remaining crew held it together to take the first point of the series

In readiness for the start of the Louis Vuitton cup finals, the team are making last minute preparations across all areas. Rewind a few days and the guys from the sail loft took a road trip to pick up a new sail from the North Sails factory in Nevada to bring back and prepare to be ready for the start of racing this Saturday.

In episode 4, Learning to Fly, we examine how this stunning design can achieve such staggering speed potential, then tie in the expertise it will take to achieve it. By far the most unique and awe-inspiring feature of this boat is it's ability to "fly on foils." We'll have the team members explain how this works, and bring to life the dramatic effect and feeling it brings while "flying." courtesy RedBull.

The act of launching the AC72 is a precarious one. It takes up to 40 team members to launch the boat for sailing and put it away again at the end of the day. All direction of the whole process is lead by the lift master Lance Manson.

After the AC72 being in the shed for five days of modifications and touch up's it was back out on San Francisco bay today being put through its paces in some solid breeze in excess of 20 knots.

n episode 3, The Cutting Edge, the AC72 takes center stage as the ultimate hero of the 34th America's Cup. As a piece of engineering, it is the most highly advanced sailboat in racing, meeting the standards now of what would be possible 15-20 years forward. The AC72 should not be flying above the water at 50 mph, but that is what it's doing.

Despite it being in the middle of the Louis Vuitton challenger series, Emirates Team New Zealand's AC72 was one of four boats out on San Francisco Bay today. It's just another vital day on the water testing and trying to get more speed out of the AC72 for the business end of the regatta.

It could have been complete farce. Luna Rossa raced against themselves yesterday - but should not have won.
