Just curious, in degrees, how close can a sailboat travel into the wind?
Forget about efficiency in getting somewhere. At what point is it just
impossible to move forward?

I understand it's approx. 45 deg off the wind on either tack. So.. that's
90 degrees out of 360 that you can't sail.
Results will differ a bit depending on boat, condition of sails etc.
