FCS II Album Laminar Twin L-XL Retail Fins

This new profile takes this further through its camber. A gentle, intentional curve built into the foil itself starting from the leading edge of the fin. Where a flat or symmetric foil waits for the surfer to load it, a cambered foil is already working. It actively generates lateral force through the turn, building hold from the moment you engage your rail even at lower speed. Think of it less like a rudder, and more like a wing that’s always switched on.

That camber peaks at 40% of the chord length forward of centre, loading the front of the foil first. The result is a fin that builds pressure early in the turn and carries it all the way through, rather than spiking and releasing. That geometry is not an approximation. It is inspired by aerospace and hydrodynamic science and built precisely to it.
