ASG-29 Coke Bottle Whistle

I had this last season and fixed by adding V seals to the fin each side of
the
rudder.

I hope some of you ASG-29 drivers have either experienced or heard o
this issue I'm having with my 2012 ASG-29. The ship has about 200 hour
on it. At about 100-110 knots I have a very loud and annoying soun
that comes from the rear of the ship. It sounds just like someon
blowing over a coke bottle to create a tone. I can get rid of the soun
by applying a little rudder although the yaw string is running tru
while the sound is being generated. Rex Williams said he thought it wa
the tail dump opening. I've put duct tape over the tail dump valve an
still have this annoying tone accelerating through 100-110 knots. Joh
Murray thought that it was the gap seal tape on the rudder. I woul
have thought that would have produced more of a buzz sound but this i
probably my next step. Hopefully someone can enlighten me as to
possible cause

I had this sound on my asg29 as well. I managed to fix it by applying V seals on both sides of the rudder.

Same as Gintas, put internal V seals each side of rudder opening.
