Like on our light sandwich windsurf boards, wingsurf boards also has the air scew so the board can "breathe".
Do you use yours?
I dont, would if I were travelling with plane, or if storing for winther - otherwise not.
As I KNOW for sure, if I open it, I will forget to tighten it the next day, and go in the water with an open vent
How about you?
And have anyone experienced issues, when not using the screw?
I havent, on windsurf boards, but still interested in other experiences.
