Yea, I have been thinking about the rudder thing for a while and I think I am going to ask for a clarification from IHCA. Seems only fair.
IWCA's policy is that Waves can use any catamaran rudders that have been manufactured by Hobie Cat Company, past, present or future, regardless of material. (I'm assuming that all the Hobie rudders are the same shape and size.)
I don't know whether that policy is actually written in the class rules, but that is what everybody adheres to.
