For 162 years the basic principles of sailing in the America’s Cup remained the same, one person would steer the boat, the rest of the crew would handle the sails. And then came foiling....

In this episode we take a look at how sailing a modern Cup boat has become the ultimate balancing act and how, a decade later and three Cup cycles down the line, foiling is an established part of the America’s Cup. With thousands of hours under their belts, crews are experts and the knowledge is spreading, but how?

As well as being a required part of this Cup cycle, the AC40 is helping to accelerate the learning both inside the Cup and in the broader grand prix sailing world

Emirates Team New Zealand coach and sailor Ray Davies explains how crews handle these sophisticated flying machines, plus we talk to foiling expert and class manager Luca Rizzotti about why the AC40 is such an important boat outside the America’s Cup.
