The only 100cm or longer mast Sabfoil provides for windfoiling is the 115 cm Red Devil Racing mast. They used to have a 103 cm Kraken mast, but on Sabfoil's web page, it seems to be gone.
The 103 mast from Slingshot seems popular, so I was a little puzzled that Sabfoil discontinued their long freeride mast. Anyone who knows why?
