: I don't know what the difference is between a foiled blade or a

: know what this is all about so good thing I don't mind asking,
: does anyone have a link I could read into in order to catch up
: with my lingo and overall knowledge?

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,
