I have read that the keel is a foil that creates lift. But I am confused.
So it does more than resist leeway (which seems like drag against leeway)?
What causes the lift? Water flow? Keels aren't shaped like a sail or a wing with one side rounded and one flatter.
What direction does this lift vector have? Straight ahead?
If water flow is perpendicular to the direction of the boat, which direction is the lift? Forward?
Thanks in advance. I am ready for the deluge of replies.
