F1 mast mounting issues

[To bad]

Anyone else had issues mounting a F1 Mast (160 x90) to pocket foil boards with bolt patterns only no tracks (165 x90). I have a Kanha Shapes and recently switched to F1 and now I cant bolt mast to board....

I saw a Stringfellow adapter on Mackite but it looks heavy.
F1 has a adapter for Sup boards I could probably make work but I think I would have to machine slots to board - https://www.f-one.world/product/4-point-foil-mount-adapter/

Also my Kanha has 5/16 (8mm equivalent) holes and F one is all 6mm

Anyone else had this issue?

You can also get the Cedrus mast and never worry about compatibility issues with any board or any foil system you want to switch to or add to your quiver in the future.

You really got me thinking. I reached out to them. I need a longer mast anyways. What is difference between Classic and Clydesdale?
I want a economical mast that is stiff enough for winging.
