Sailboats That Go Faster Than The Wind

I just cought the end of an America’s Cup race. The boats crossed the line at 40 knots! Apparently, they go FASTER THAN THE WIND! How can a boat go faster than the wind?

They use adjustable keels that function as st of a “water sail”. So, in the same way you set a sail for the wind to push you, you can set one of these keels to do the same with the current, or that’s how I understand it.

UPDATE: I just watched the second race and I want to point out that they’re not just going a little faster than the wind, they’re going twice as fast!. A 2knot current and windspeed of around 20knots and the boats are going up to 40 knots.
