I am getting the foil whistle sound tha i have read about. seems to come about when i hit approx 15mph (according to my gps). don't know if it will disappear i reach a higher speed. but anyone else getting that noise. comes from a diffence in pressure b/w the wings.... |

Np's alu whistle is well documented, even a video cure.
Naish does a low throb with bubbly background. |

My Makani Kohola makes funny high pitch sound. Kind of liking it, left it alone. |

Last nite while foiling was thinking how quiet the whole thing is, so you start hearing all kinds of little noises.......I could tell when I was getting close to a breach (wing close to surface) with a bubbling noise..Trippy fun
Have wondered whether it would make sense to have a whistle hole on the mast so that you know when you are too high....but then I just got a bigger mast _________________ https://www.youtube.com/watch?time_continue=2&v=zw0MgkO7VXw |

My GoFoil makes a lot of noise.
It starts when starting to fly, pitch goes up with speed.
Then goes completely silent when very fast.
It used to drive me crazy , but now it's a great indicator of my speed, esp when accelerating surfing a wave.
When it goes silent it's "oh oh here comes the breaching" time |

Same. i breached so much early on I wondered about taping drinking straws to the mast about 4 inches above the fuselage. |
