Keel Lift

Jay,

This is the kind of thing you can answer fairly easily using a search engine, but let me answer your question with another question: How do stunt planes fly upside down? Answer that, and you have answered your question about how keels can produce lift forces.

(Hint: can a symmetrical or even a non-cambered (flat) airfoil produce lift? What is the relevance of "angle of attack"?)
