: Do a few searches on the Coanda effect or Bernoulli's vs. Coanda
: effect. Coanda effect is the surface attachment of the flow as
: it exits the surface. The curve of the foil increases the push
: without causing stalling. It is why a sharper paddle edge works
: better.
: Play with different shapes under the running water faucet and
: notice how it wraps or shoots outward.
: All that being said, I have just redesigned my skeg box design
: using flat 1/4" King Starboard stock for the blades.
: Here is a link to start with.

: Hope this is helpful,

Interesting link Reg, interesting reading though I have issues with some of what's said. Reflexed wings lift and the trailing edge is pointing upwards, so deflection is not lift.
