I have experienced this on several occasions. I have not taken specific note of the wind speed or angle when it occurred, but in general, if there is a strong blow from somewhere aft of the beam, there is a noise generated, which creates
some degree of vibration.
I have assumed it is when the combination of wind angle and speed causes a whistling or harmonic effect with the furler opening of the mast.
It can be attention getting, but we try not to pay any attention to it anymore. We have added it to the list of other “charms” of sailing life. Sorry I couldn’t provide a solution to eliminate it.
