[Rhodes22-list] Keblinskas & Wind-induced noise in rigging/mast while docked

[petelargo]

I just went through this on the keys trip. I also get a hummmmming noise. I
felt around the boat and it did not seem to be the IMF. I could feel the hum
more in the boom, but that wasn;t the source either. It was the boom cord
going from between the rear stays all the way to the top. It gets a
frequency going. I bungeed the boom cord at the rear to the rear stays and
that was all she wrote. 


Al:

I get a hummmm... which increases as wind increases... HUMMMM...
