I'm trying out a new rudder design for my kayak, and (aside from a good NACA
profile) I need to know what the maximum rudder angle would be. I assume
the maximum angle would be at minimum steerage for a kayak (around 1.5
knots).

Thanks

Figure at least 40 - 45 degrees. I'd suggest the design limit condition is
actually when a big wave picks you up when you're too close to the beach,
you start to surf in and jam your foot against the stops trying to get back
out to sea... (person experience

I was told not to use kayak rudder for turning, just set for tracking
angle in wind, waves, and current. As such I would not be as concerned
about stalling as I would about drag, so keep the rudder angle low. Sorry,
I don't know how to calculate rudder drag.

Max rudder angle for what? Sideforce or sideforce/drag?

Not sure? try +- 30 deg.
