The FCS II Modern PG Keel Twin Fin Set is an upright keel template designed for traditional fish shapes. Lower sweep (rake) than most conventional, 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.
