[Rhodes22-list] humming center board

[Rafe]

Had a great sail yesterday.  Amy and I sailed down to the Indian
Dunes/Beach.  Plenty of wind and the lake was very flat.  Sailed for 8 hours
total - longest sail so far.

Question:  Is it normal for the center board to vibrate a little?  It makes
a low hum (d sharp).  We have to be moving at a fairly good clip to get the
hum, but on the way down to the dunes we could get it for over an hour at a
time.  I just don't want it vibrating loose or something.
