This FCS II AM fin template is Al Merrick's classic template in a medium sized fin. This fin is constructed with FCS' new AirCore technology.
What is AirCore?
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 moulding process making it much lighter while allowing total manipulation of the flex.
