The FCS Modern Keel Twin Fin Set is an upright keel template designed for traditional fish shapes. A lower sweep (rake) than most conventional and wider based keels which allows it to pivot in a really tight radius. High area and depth not only delivers a feeling of control when pushed harder on the open face, but helps to maintain tremendous speed through roundhouse cutbacks. Recommended for all board types including fish, funboard and twin fin boards. Designed to fit the FCS II Fin System.

Product Construction
Performance Core + AirCore
While Performance Glass (PG) is still very popular with advanced and power surfers, Performance Core (PC) fins have a more progressive flex from the base through to the tip helping the everyday surfer to maintain drive and speed through turns. PC fins are versatile, very responsive, and can be used in a variety of different conditions. AirCore technology reduces the amount of Fiberglass required in the RTM moulding process making it much lighter while allowing total manipulation of the flex.
