: Does anyone other than ONNO make a rudder with an actual foil
: shape? Not just a flat piece of aluminum.
Jeff,
I use this one and really like it. It is smaller than most so it does not have the power (or the drag) of some. I have found it works fine for the conditions I paddle in. You could always get the tandem blade if you wanted more umpa. It took a while to get used to the thing pointing up when I am not using it, it makes you feel a little like a Ruddy Duck. When you feel how easy it is to deploy and retract you will wonder why you waited so long to get one.
