Yes that’s exactly it. I also get it in tacks when it’s choppy
Same for me,pushing the angles upwind in choppy conditions.
But i think it is mainly an avoidable design failure.
Same rider ,same technique and very similar conditions and one mast performs fine while another totally sucks.
My Gong V2 alu mast did it also. The reason to me seemed to be the finish was far too rough. Refinished it and never ventilated again.
My my project Cedrus Clydesdale is known for ventilating but got mine used and sanded it with 800 and 1000 SP and never experienced any ventilation
Could you explain how and what you finished your Gong v2 alu mast with?
gong v2 mast is terrible…

I am sanded my own made carbon mast slightly with 1000-2000 grind paper and water horizontally, no more ventilation issues, I hope it works with other masts too.
It’s works similar like vortex generators in aviation

What mast have you experienced this on? F-one?
I use my own made mast, but I had ventilation problem too, I tried different finishes also sanding methods but 1000 grind horizontal sanding just resolved ventilation issue completely.

Has anyone experienced mast ventilation this on the F-one 14mm 95cm carbon mast?
Mast ventilation isn’t technique.
Kite foiling is probably not the best way to learn the limits of your foil. You have all that speed and power available at all times, if needed, which does not exactly teach being sensitive. Think of windsurfers for example, some are using bigger fins in order to avoid the fins to spin out (which is, in a way, very similar to foil mast ventilation), while others have no problem using way smaller area and thinner fins in the same conditions, which helps to reduce the drag significantly, which then helps to learn riding with less power needed from your sail and gives a more manoeuvrable and enjoyable setup. A positive feedback loop. It’s the technique, and experience with a particular setup, near its limits (not way pass the limits) that helps to understand how far can it be pushed before it starts acting up.
I am guessing you are just taking that mast (that ventilates) outside of its comfort zone. There seems to be crazy many versions of F-one and Gong masts, with different thicknesses and chord length and what not. Maybe there are masts in their range that suit better for kite foiling.

Well you are guessing wrong .
Nothing to do with technique …and frankly this argument is boring me. Usually from riders who have never experienced it.
I currently have 2 masts completely different profile . One ventilates and the other dosent.
Same rider. Same technique.

There is a reason why there are masts with different profiles. If you think that the only good profile option is the one that does not ventilate while you are kite foiling with it, then so be it. There is much more than kite foiling, you are perhaps just not using the right kit in your conditions.

Oh dear ….and the question was « Has anyone experienced ventilation on the 95cm 14mm mast »
It’s funny …if you really knew what ventilation was you wouldn’t be saying things like « If you think that the only good profile option is the one that does not ventilate while you are kite foiling with it, then so be it. «
I mean dude thanks but really you ain’t helping anyone here.

I use a 14mm F-One in 75cm for DW SUP and Winging in measured speeds up to 50km/h, various sea conditions, fresh and saltwater and never had this mast ventilating.
I only ever had problems with mast ventilation when kitefoiling on a Alu mast that had a chip on the leading edge.
Do you have a video of your mast ventilating or can you further describe how it feels? What frontwing are you using?
I was on a Slingshot phantasm kite foil (102cm mast), I’ve also experiences ventilation on the Lift X2 masts which has a thicker section than the newer M2 masts where it does not seem to be as much of an issue.
“Could you explain how and what you finished your Gong v2 alu mast with?”
About 8 coats of filler type paint sanding between some of the coats until it was flat. You could use a filler…
Last paint coat sanded 600-800 smooth. Slight 600- 1200 texture is good. But the texture of 40 grit sand paper that’s on that mast, is way over the top bad IMO.
So sand the current coat of paint to bare aluminium - then 8 coats of spray filler paint in between? Why so many coats?
Did you finish with some kind of laquer?
Thanks
Most of the times the ventilation happens because poor manufacturers and not because of design.
It’s can be fixed with specific sanding technique, but not always

Agree, all the masts with ventilation I have seen it in have a flaw in them from the manufacturer. Seems more common in thicker masts too.
Once you start sanding youll see the rough surface is.a result of the manufacture sand basting the extruded v2 aluminum mast with a very course grit media, before powder coating. So you really can not sand it smooth without tanking off a bunch of metal. So i used the many coats of paint to fill in the low spots…
Honestly its a lot of work and might not be worth all the effort compared to just buying a carbon mast.
The first V1 aluminum mast surface wasn’t bad but it was a noodle for heavier guys.
This week they came out with the v3 aluminium mast which might be a better option.
