What kind of a stupid statement is that?
Any an all keels creates force and slows a boat down but they are a
necessary evil to give direction and stability. With or without wings.

A fixed keel is a creation of drag as well as lift.

Paul Yates reference to a wing keel not creating a force in any
direction was describing how if the boat is sitting flat in the water
the "wings" should be flat too. In other words the wings cannot be
angled up or down like the elevators on an airplane. Yes, the wing
keel will creat lift when going upwind like any keel but not "lift"
going downwind to get the boat to "get up on plane" Once again, winged
keels on production boats bacame popular after the Americas Cup because
rummys thought they were high tech when in reality they were just a new
way to add weight without going deeper. If they are so great where are
they now? As I said before bulbs are now the rage.
