Re: HUMMING RUDDER

A while back my rudder started to hummm mysteriously. I did nothing to it and it stopped humming after a few weeks. Maybe it's depressed?? Anyone have some rudder prozac?

Maybe it was just bored. Not enough scary downwinds...

SInce rudders start humming only past a certain speed... maybe you've slow down paddle harder and it'll humm again.

Nah E.T., it's more like breaking the sound barrier. Lots of shaking and vibrating at first then everything quiets down. I don't have any plans to go subsonic again. And yes, my boat and rudder are very bored. Hopefully once I find those tanker waves that will also be solved. Hasta

No,no,no. He has definitely slowed down. I'm sure of it. No doubt in my mind. In fact, I think he's getting paralyzed with fear that I'm going to beat him in the race this weekend. :o

Dave, it might be a good idea to stay away from those mushrooms growing in your yard.

So... Has anyone experimented with marine bearing grease in the rudder shaft tube and on the shaft to help with "rattle". of course there has to be some play here, just had a grating afternoon listening to the rattle in the chop. If there is enough lump to actually get a push the rattle disappears as the rudder loads up.???????

My surfski was humming like a thousand bees were on my back. A friend paddling ten meters away could hear it. I could feel vibrations in the hull...
Since I live far far away from Mr Fenn, I didn't wanted to ask for another rudder and have to wait for a few weeks to get it... Instead I re-shaped the rudder that was buckled and got it straight. Since then, no more humming nor vibrations.
The link below shows how it's been done. Sorry, the text is in french but there are some pics.
