The FCS II Carver PC Carbon Tri Fin Set is part of the FCS Essentials range. This fin is designed so you get what you need for point and reef break waves. The Carver is a taller fin with a pronounced sweep so you can charge down the line. Along with the fuller tip this gives exceptional control off the bottom and on the open face. Theres a flat foil on the inside of the outer fins so you get consistency and predictability. This is great for power surfers who push hard against their fins and draw out their turns. PC Carbon means the fins have a fiberglass construction like traditional fins. Added to this is a carbon fibre layer so you get stiffness while maintaining light weight. Able to handle a wide variety of conditions, youll perform best with these fins in open face walling waves. This fin is designed to give you the best performance from your board with deep concave and extra rocker. Note, the FCS II Carver PC Carbon Tri Fin Set is for exclusive use with the FCS II Fin System so will not fit in the traditional FCS Dual Plug System.
