Regular sails actually work similarly to a wing, in that pressure differentials on either side create a force we call lift on a plane, rather than simply being "pushed from the back" by directly catching the wind. That's why a sailboat can go in almost any direction regardless of which direction the wind is blowing.
- jessriedel 8y agoEdit: sorry, nevermind, I was confused as to what you were claiming.
- jessaustin 8y agoReading the parent carefully, I find nothing that contradicts what you have written in response. Pressure is just force over area.
- jessriedel 8y agoThanks, upon re-reading I agree. I misinterpreted the "pushed from the back" statement.

- jessriedel 8y agoI misinterpreted his original point, which I intended to disagree with.

Hydrofoils achieve speeds greater than 3x wind speed though their stability doing it is a bit alarming. https://www.odt.co.nz/sport/yachting/how-fast-can-americas-cup-yachts-go https://www.odt.co.nz/sport/yachting/how-fast-can-americas-c...
