: Btw, foil shape is often not what people think, it's not a rounded
: nose tapering back to a sharp pointed tail. Maximum thickness
: should be in the range of 25-35% of the chord (length from the
: front of the foil to the rear). Also generally the nose needs to
: be rounded and the tail fairly sharp but in water at least
: does't need to be pointed, squared off works fine.

Using a foil shape for your rudder is important if you want it to slow you down the least amount possible, and cause you to turn with the least amount of angle used (more angle means more slow down).

I think that if you get a skeg turned enough to stall it, then your kayak doing something very odd?
