Hi All
I stopped surfing in 1965 ( - Midget Farrelly as World Champ - ), so am not up with the latest surfboard technology

I recently bought a surfboard with a Salomon S-Core inside, to use as a kite board. I have been told conflicting information about when to
open the vent in the deck. Haven't had much luck researching it on the internet. Can someone please give me the real story??
I can understand needing to open it to dry out the core after a ding, or during aircraft flight. What about during storage between sessions? Can't imagine having to remember every session to tighten the vent before going in the water, and loosening it after each session....sounds like a recipe for a "Senior's Moment".
Hang on ....I AM a Senior!!

Would also be interested in whether this system is still used.
Cheers,
Hemi Tuwhaaka
