That hum can be reproduced just at the docks. It usually means some aspect of the rigging is tighter than the rest and as the result - the mast vibrates while being more tightly secured in some areas than the others. You'll never hear the mast vibrate it will be channeled through the tightest or loosest part of the rigging just depends on direction of pressure. Usually it will be the loosest but not always.

It also indicates that you are not dialed in and there is too much pressure exerted on the mast and all its components in one particular area. Has nothing to do with the keel unless you have a centerboard arrangement. The singing keel is different than singing rigging.

In instance of example - my roller furler is sometimes a bit with slop - but where moored - the wind blows into the furler putting pressure on it. The running backs will start to hum unless I tighten them and thus tighten the mast and forestay...


Humming / singing is an indication that you are not dialed in with your sailing plan and thus not getting the most efficiency out of it... IMHO...
