The FCSII Split Keels are the perfect choice for performance driven fishes and planing hulls. If you have a Dragonfly, Mach1, Hexafish or any planing hull this is the fin to use. With greater surface area than a traditional quad set you’ll never skip out on a hard bottom turn or cutback again. The Split Keels have a flat inside foil which gives your board that slick feeling through the water that we all love about quads.
