FCS II AirCore 5 Fin Set Large Flat Pad The center fin is smallerThe Al Merrick template has a wide base for drive off the bottom, more rake for big carves, a finer tip for release off the top, and the signature smaller center fin frees up the tail. Fins with AirCore Technology feature a pressed polyurethane foam core that mimics the geometric foil of the fin. AirCore technology reduces the amount of fiberglass required in the RTM molding process making it much lighter while allowing total manipulation of the flex.
