Designed by Hawaiian Kai Sallas, this high performance longboard fin strikes a balance between speed, manoeuvrability, drive and response. Can be adapted to SUP's and modern single fin boards
The FCS system (Fin Control System) was designed by Brian A. Whitty in Elanora, Australia, and patented on November 7, 1995. It can be recognized by the 2 tabs on the fins which are designed to fit into a securing plug that attaches the fin to the board.
