Here is an old but still cool video about how sailing works. Of course no mention of wing powered hydrofoil catamarans, sailing at 3 times the wind and sailing at 20 degree jibing angles, but it’s still good info.
Video background – Northern California has a storied, 500-year history of sailing. But despite this rich heritage, scientists and boat designers continue to learn more each day about what makes a sail boat move. Contrary to what you might expect, the physics of sailing still present some mysteries to modern sailors.
