Former FCS employee, novice surfer and GSI owner is Australian Mark Kelly (or “Kel”). In this video he explains how he “designed” the parabolic longboard.
Global Surf Industries (GSI) surfboards are made by low wage non-surfers in the Cobra factory located in Thailand. You can find them for sale in surf shops owned by people who forgot why they started surf shops in the first place.
