Can ships go up river?

Why do boats sail faster downstream?
The boat must be moving somewhat sideways. In that “crabbing” motion, the keel moves through the water with an angle of attack. Just as for the sails in the wind, that causes the water on the “high” (more downstream) side of the keel to move faster and create a lower pressure.
How did medieval boats travel rivers?
