How can the yacht proceed forward in the headwind?

yacht -headwind

I heard that yachts can go forward even in the headwinds.

How can they go forward?

Is there a way to make a sail?

Of course not in a headwind

It's possible against the wind
It's not exactly going straight
You can think of it as zigzag at 45 degrees

I read a book by someone who traveled around the world on a yacht
We can use a triangular sail and zigzag it
The problem is that there is no current in the windless area
