Description
“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
The upright nature of this template promotes tighter turns and therefore comes to life in punchy, hollow waves and when performing vertical turns, but it will also suit conditions where you need immediate start-up speed from the take off. The full, robust profile of this fin from base-to-tip allows surfers to push hard while still getting that freedom to turn easily.
Recently Added, the quad rear template for the CI Upright features a more raked outline to compliment and ‘settle’ the set when paired with the side fins. These quad rears have more curve in the trailing edge and a narrower tip compared to the side fins which offers a smooth and controlled feel, yet it will still react and turn tightly in steeper sections.
Overall, the CI Upright Tri-Quad set is suited to boards with the more relaxed rocker.
Thruster = Fast and loose. Quad = Drivey and loose.

Performance Core (PC) fins are made using a multi-layered resin transfer molding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light, and can be used in a variety of different conditions.
