>> Numbing cold saltwater showers Ben Ainslie and his crew, as they practice to defend their America's Cup World Series lead this weekend. They call it a gut buster, a series of short, intense maneuvers requiring frequent adjustments and total concentration. The catamaran is called Rita. All of Ainslie's Olympic gold winning boats have shared the name.
>> It's amazing sensation when you lift up out of the water. It is akin to flying an airplane. It takes a lot of focus and concentration. And then of course, when you're in a racing environment, you've got to deal with trying to beat the opposition at the same time.
>> Rita's sail is as tall as a 737's wingspan and can it fly. As Reuters' Alex Smith saw firsthand when he was invited aboard.>> Ben Ainslie and his team will be heading off from here in Portsmouth shortly to Japan, where they hope to defend their lead in the America's Cup World Series and then take that forward to the America's Cup itself in Bermuda in 2017.
>> Ainslie will face fierce competition from New Zealand, Sweden, Japan, and a French team, all vying for a chance to take on champion Team Oracle USA one on one.>> I think the team are really proud of getting ourselves to the top of the fleet. But we need to keep doing the same things that we've done in these other events.
Keep that focus, not get too distracted about some of the teams coming up behind us.>> A well choreographed crew just trying to keep their boat flying.
