Hi All,

I don't know if John still producing Stealth rudders ??
I have T foils rudders and also Dotan rudders which are fitting well on my Stealth #539. Then I experienced that T foils are really efficient to prevent diving.

My problem is that the boat is "singing" "whouwhou..." because of vibrations in the rudders. Do you know what can I do to stop them ?
Thanks
Bertrand
