The upright nature of this template promotes tighter turns and comes to life in punchy, hollow waves and when performing vertical turns. It can also suit conditions where immediate start-up speed is needed from the takeoff.
The full, robust profile of this fin from base-to-tip allows surfers to push hard while still getting freedom to turn easily.
Britt Merrick: "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."
Britt Merrick: "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."
