Designed by Al Merrick for radical, progressive surfing, the FCS II Al Merrick PC Tri-Fin Set features raked side fins for exceptional speed and drive, paired with a smaller center fin on the medium and large templates for fast release through turns. Built with updated Performance Core construction and ultralight AirCore, this fin set excels in hollow, steep waves and punchy beach breaks, and pairs best with performance boards featuring deep concaves and moderate to extreme rocker within the FCS II fin system.
