The Twin Fin has a retro 70’s feel, with updated performance qualities.

It was originally designed and hand shaped by Britt Merrick when asked to compete in a surf contest where shapers ride retro boards they have created themselves. Inspired by a twin fin that his father Al had shaped for himself in the late 70’s, and that a friend had recently found at a garage sale, Britt took a template off it, drew it on a blank and updated the rocker to have a more modern feel with added positive drive and carving ability. Thus, the new CI Twin Fin was born. The Twin Fin has been tested by Britt, Dane and CI Factory pilots in everything from weak beach breaks to good Rincon and has proved to be a fast and fun wave catching machine.  To offset negative characteristics of a usual high-volume retro design, the Twin Fin’s rails are tapered and relatively thin feeling for added sensitivity and responsiveness.

The Surftech Breakdown: Surftech’s Fusion Dual-Core offers the best of Polyurethane Foam (PU) and Expanded Polystyrene Foam (EPS). EPS through the center of the board delivers more paddle speed increasing your wave count and also aides in speed generation once on the wave. PU on the rails helps absorb vibrations, allows you to dig the rail deeper and helps with rail hold in and out of tight turns. Surftech has been building boards utilizing these two different foams in one blank for many years but the big innovation comes with how these two foams are bonded together. Thermoplastic Polyurethane, TPU, is sandwiched between the EPS and PU to create the perfect combination of materials and maximize the rebound and the dampening at mach speeds. TPU has a high abrasion resistance, high shear strength, and most importantly high elasticity. On top of the ALL-NEW fresh tech in the multi-density foam core, the blanks also utilizes a stringer-less technology with added carbon down the deck and hull of the board, as well as carbon tail patches for break strength, response and control. We made sure to put science and design at its best and you can thank us later!
