Do square rig sails count as airfoils? I thought they could really only go downwind?

- kragen 1y agoAs I understand it, they can go somewhat crosswind, which is all the wing of a 747 manages too. (An angle of attack of 2° is probably a lot better than you can do in a cutter, though, I imagine.) But I don't know much about aerodynamics or sailing, so I could be wrong.
