As a Tri-Quad (5 fin) setup, it offers versatilityNuse the thruster for precision and the quad for added speed and hold.

The Performance Core (PC) construction ensures a lively, responsive feel underfoot. Compared to the FCS II Al Merrick Tri-Quad Fin Set, which has a more raked template for drawn-out carves and added stability, the CI Upright is better suited for quick, reactive surfing and fast transitions.

When paired with the Channel Islands Better Every Day board, this setup excels across a range of conditions, providing a dynamic mix of maneuverability and speed. Perfect for surfers looking to push their performance. Overall, the CI Upright Tri-Quad set is suited to boards with a more relaxed rocker.

"We designed the CI Upright because our surfboard range extended well into the hybrid and step-down categories, and we needed a fin to maintain response and turning performance on our boards where the rocker was a little more relaxed and flatter."

"This fin allows you to gain start-up drive and acceleration really quickly, yet still feel loose and free off the top. Many of our team riders have also gravitated to this fin on their high-performance shortboards and step-ups where they wanted less resistance and the ability to stay right in the pocket." - Britt Merrick
