Thanks Gordon, Spirit is less then a year old and is equipped with the stepped- diameter rudder rod. Still, the rod may be a contributer to the harmonics, so next time I'll check this more closely . Hey, there's nothing more fun then hanging over the stern and fidgeting with rudder parts while sailing down a narrow, crowded channel right?

Hi, Jim: I just experienced a similar thing on a sail yesterday. In my case (I'm not sure if your setup is the same as my 1983 model), the steel rod that the rudder hinges on had ridden up when I raised the rudder previously. Then when I lowered it, the rod did not go down completely with the rudder, leaving the rod short and out of the lowest gudgeon (right word?). This has happened before, and when I pushed down the rod completely (so the cotter ring can't go any lower) the humming went away. I determined yesterday that I just need to ensure that the rod goes all the way down with the rudder every time I lower it for a sail.
Have a great weekend!

Sailing even with a moderate breeze makes Spirit's rudder hum loud enough to drown out the Pillar Point fog horn. The rudder is new and doesn't seem to be warped. Is there a trick to stop this or is it just a Monty thing?
