Amel 55 mizen vibration

Jose Alegria
 

Dear  amelians
Today's topic concerns the Amel 55 model
At   marina berth , when the wind enters from the stern at 130-150º angles and with 10-15 knots of wind, there is an enormous vibration in the mizen mast; it is something that does not always appear, but that noise in the main cabin  becomes highly annoying.
Does anyone have an explanation for this, or some solution to this problem

Kindest regards

Jose,

 

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.

Dear Jose,

I certainly do not want to keep you away of this charm, but you might try to wrap a hallyard a few times around the mizzen. This changes the airflow and might diminish the vibration.

Jose,

You might also consider locking the the mizzen traveller off the center line and tie a preventer line going from the end of the mizzen boom to an aft stanchion or pad-eye.

Wow, Jose, I’ve never had this happen on Kincsem.  I guess the answer is not to go to a marina and anchor instead!  Seriously, maybe you deploy a bit of the mizzen sail to change the rhythm?  Je
