    Give your board a turbo boost.

    FCS' Performance Core Surfboard Fins are designed for lighter surfers that want a responsive and peppy fin that'll react and handle diverse wave types. The larger raked fins produce power and speed, while the minimal center fin is quick and springy to aid in rapid turn movements. And because the Arc is made of Performance Core, the fins feel like traditional fiberglass, only lighter, for a smooth and uninhibited ride.

    • A lightweight set of fins for improving your surfboard
    • Foil technology improves on-water hold and speed
    • High flex rating for enhanced durability
    • Item #FCS0022

    • Familiarity: I've used it once or twice and have initial impressions

    I bought these fins I while ago but I was landlocked :(. I finally had the chance to take them for a spin. I replaced my standard tri-fins (FCS M7) with these fins using the quad setup. Immediately the boards feels easier to paddle.
    I'm not an avid surfer so I cannot give all the juicy technical details. All I can say is that it feels good to have these fins. I was a little nervous that these fins would mess with the stability of the board (Very important for someone that surfs once a month when lucky). But I felt confident on the board and I didn't miss my old fins.
