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).

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
