I don't know the answers to these things other than what I've experienced sailing. For example, if I'm going dead down wind in a sailboat at 3 knots in a 3 knot wind, then I'm just getting pushed and the sails (foils) are not generating any lift.
I saw an hour long show about the ship stuck in the Suez Canal. They analyzed the speed of the ship compared to the current speed. Here is a small sample.
