I have found that the mast on my 9.1 likes to pump in steep waves or high wind.

Even in gentle swells if I sight up the mast I can watch the top of it move for and aft with every wave. I have tried different backstaytensions and that only seems to help a little. With the top of the mast flexing like that it is impossible to maintain any steady sail shape.

I also found that my mast will vibrate and pump while sitting on it's mooring in anything over 19 kt.s of wind.

The vibration seems to start with the tuff luff and eventually gets the whole rig going. I am sure this is not good for the rig in general.

I suspect limitting mast pumping was one of the reasons they put the baby stay on in the first place, have any of you used other methods to limit mast pumping and vibration?

Is anyone using checkstays and if so, how did you rig them.
