These FCS AM-3 Surfboard fins are the same Al Merrick fin template you have grown to love in a smaller size. These fins would be great for the lighter surfer or to loosen up a tight surfboard. These FCS fins are made from FCS' performance core material.

Performance Core material and construction is designed to deliver the feeling of a traditional fiberglass fin with the added performance of reduced weight.  The RTM (Resin Transfer Moulding) process produces a lightweight fin with remarkable flex, a smooth feel and an impressive aesthetic.
