Been using the 2019 90cm mast on my 2020 foils with no issues. Got the 2020 95 cm and it hums and I can feel it vibrate in my feet. Has anyone had this issue or know how to fix it? I'm told its the trailing edge but what to do to solve it and not make it worse.

Sharpen the trailing edge might help.

This was a common problem with the NP Pinks. Sand the trailing edge at a 30 degree angle - not square.

Swap it for another one if you can as the whistling may not go away..no matter how much you sand or file the edges. On the other hand, if you want to chase away sharks or warn others that you are coming their way then keep it Smile
