FCS H4 surf fins look and behave differently compared to other fins. Swiss engineering precision combined with a highly evolved model provides an unprecedented level of control and predictability at high speed.
Radically different side and center fin designs create a powerful fin set with optimal speed and ride
SIDE FIN PROFILE: The lower section produces maximum acceleration, while the hatchet-shaped tip provides stability and control.
CENTRAL FIN PROFILE: The steeply angled elliptical profile reduces drag and provides a feeling of predictability when relaunching through turns.
A thicker base with a tapered tip maximizes flexibility and regulates the release of energy during transitions between rails.
These fins cover a wide range of conditions and perform particularly well in solid conditions.
