The rudder on my 1975 Oday 20 needs to be rebuilt (by me). The current condition and lack of a decent foil cross-section lead me to believe that this is not the original rudder. I've got good info on how to generate the foil numbers, but I want to make sure that the length (up-and-down) and width (fore-and-aft) dimensions are correct. If anyone has access to an Oday 20 rudder and would be so kind as to post the measurements, I would be most grateful.
