[C320-list] Humming noise from boom

[Scott Thompson]

Humming, whistling and other kinds of noises are very common when the 
wind blows across the slot of an inmast furling system at just the right 
angle.  If you search the web you can find lots of anecdotes.  The usual 
solution is to get a sailmaker to make up some kind of an antiwhistle 
strip that you hoist up the back of the mast to interrupt the airflow.
