that is true for 2 sail boat, but if you do the classic raft boat with just between 2 horizontals?

Many expected an explanation from Derik but the reason he didn't do that was that guy himself exlplained all and most of them was correct

Wow! I was amazed how little most people know about how a sailboat works. Maybe other people want to jump in on my explanation but I explain it simply my saying that a sailboat can do more than just go downwind because it has a keel. With a keel the boat is like it is on railroad tracks and does not move sideways. The sail can be used to blow the boat down wind and obviously more and more degrees off of directly downwind because it has a keel. As the wind is 90 degrees off one side the sail can be used as a wing and make lift 90 degrees off the wing surface and move the boat forward and the keel prevents the boat from sliding sideways. Now you could see that this technique could be used to go a few degrees upwind and may a few more degrees and a few more degrees… You can keep doing this to about roughly 45 degrees into the wind. You can not go directly up wind. I hope this helps and is a very simplified explanation of how a sailboat works.

Whit the wind is actually one of the slowest
Because the sail is only pushing the boat forward instead of pulling it forward

Think of flinging watermelon seeds by squeezing them between your fingers. Which way does the seed go? Well, the sail boat is the seed, the wind is one finger squeezing in one direction and the water against the keel is the other finger squeezing in the other direction. What direction is the sail boat going to go?
That's the best way I've heard it explained.
