Josh Ku is an Australian waterman best known in the surf world for charging some of the heaviest slabs in Oz. He's taken on foiling and is quickly becoming one of the best prone and downwind foilers. In the podcast Josh talks about going from foil-curious, to closet-foiler, to full blown Foilbrained. Why it's best to dive in head first in downwind. The risk and fear of riding massive surf. Why foiling is so addictive. And what's different about foiling in different oceans and energies.
