Take an inside look behind the development of the FCS H4 and discover what makes this fin so unique. Learn more about the design process and thinking that influenced the unusual combination of two different templates and a swiss partnership that would result in a fin with unprecedented speed and control.

Think speed – The H4 looks and surfs different to any other fin. Precision swiss engineering matched with a highly evolved template provides an unprecedented level of control and predictability at high speeds.

The future has arrived – Specialised swiss construction using the latest in robotic automation, ensures absolute accuracy, resulting in a fin so fine-tuned, nothing is left to chance.

Two unique templates – Highly efficient foils, combined with two radically different centre and side fin templates, provide an unprecedented level of predictability & control at high speeds.

High density carbon fibre – Custom uni-directional orientation means more of your energy is transferred into speed than any other fin. Light and super strong.
