Why do some skis whistle?

[75Tique]

Because they dont know the words???

 

[MarkM]

clearly...

Its gotta be a harmonics problem. water flowing over the holes creates pressure and when just the right combination of frequency/pressure is reached you whistle.

 

My first Obrien world team howled. So did my goode 9200 and a radar senate my D3 did not - so if the pressures don't line up right no noise. Could probably take a ski that howls and deburr holes and see what happens.

It’s the new Whistler fin pro.

HO VTX circa 1994 was a whistler

My CG fin whistles when I don't use the mini-wing. I always assumed it was a built-in alert for an incorrect set up.

I posted this back in 2017 when this topic came up:

 

Never, but it would be neat to have an audio feedback device indicating speed that attaches to the ski. I found this patent intended for tennis rackets, golf clubs, and bats. Why not a ski?

 

Here's one for golf http://www.swingwhistle.com/

 

@AdamCord @adamhcaldwell I think this needs to be another Denali exclusive feature. The GUT-Whistle ...

A training and marketing winner!

 

Now I'm wondering about the real purpose of the hole in that "Cypress Gardens" Tech-85.

My first "real" waterski was a KD7000 from the early 2000's. The blue one, just like in this picture:

 

 

 

It whistled like crazy. I've never had another ski do that... at least not to nearly the same extent.

@pgmoore had the very same ski, no whistle...

But some Goodes I owned they whistled! It was fun!

I think it is the fin box. I put some duct tape over the excess slot in the front and back on a whistler and it seemed to learn the words..

I had a Skurfer, man that thing whistled loudly! Could hear it from inside the boat easily. Could play a catchy tune over rollers.

When the Adams first suggested putting washers under the fin block I did it to my Mapple 6.0 and it started to whistle, like @A_B I put duct tape over the gap and it stopped whistling.

It chases the gators away.

[sunnydaysmn]

I had a SKI that whistled can’t remember which one .. Obrien, HO or a goode.

I thought it was cool!

The old wood Hook had a nice whistle - almost bought one just for that

[Intheday]

Had an ex cable park wood trick ski with an aluminium fin, that thing whistled so loud that the first time it whistled I though someone from shore was trying to get our attention.

I had an old Saucier that whistled at everything! Had it take a 90 minute video class and that fixed nothing . Somehow I felt safer! B)
