I've seen you guys refer to rudders and lift before. I've seen reference to
making rudders in a foil shape, is this what you mean by section shape? I've
seen probably 30-40 rudders mounted on kayaks, but they've all been the flat
blade types, although I've been told foil shaped blades exist.

Here is where I'm really lacking in understanding all of this: How does a
skeg, essentially a flat piece of metal or composite, aligned with the boat,
generate lift? I see the skeg as creating lateral resistance. Is this the
same thing as lift?
