This is a scientific Americans 60 second science. I'm Steve Mursky.

Land over in some better breeze at the moment,

flying a hull, making some good distance back now in that breeze in the middle of the course that is slowly materialized.

Lee McMillan, second Helmsman for the Land Rover Ben Ainsley Racing America's Cup team.

He was calling one of the races in the America's Cup World Series New York

session in the Hudson River on Friday, May 6th.

Before the races, Martin Wittmarsh talked about some of the technology of these boats. He was a mechanical engineer

before becoming CEO of McLaren Racing and then CEO of the team that will try to

win the America's Cup for England in 2017.

We call them the yots.

When they're flying, only less than 1% of the surface areas in water.

99% is in the air.

So these are very aerodynamic boats. So we are in a program now which goes towards Bermuda next year for the 35th America's got challenge.

So we are one of the challenges to the Oracle team,

USA.

And we are in a process here in New York of competing with what is called an AC45. So the boats we have here,

they have wings, they're hydrofoiling, catamaran, but everyone is using the same boats.

And the winner of this series, the World Series, gets points that go forward into the qualifying process.

At the end of this year, we will launch the cup-class boats.

So these are about twice the power.

The savers are down in cockpits, unlike today.

A lot of the power is being generated by these four grinders
