AU Fins is founded on innovation and free thinking! A very misconstrued concept that many fin companies and shapers believe is that the flex in the fin is most crucial. Although flex in a surf fin is necessary, it is not the most important element. The shape and contour are actually the most important parts to making the highest performance surf fin on the market. Flex and foil follow in line AFTER shape and contour. Today’s largest surf fin companies do not want to veer too far from the idea of straight fins only. As a result, flex and foil are their only changes due to the fact that a change in mold and manufacturing can be extremely costly. These large fin companies pour millions into advertising campaigns, team riders, marketing geniuses, and master graphic artists to create and recreate fins that are visually stimulating. Granted, the sizes, the flex, and the foil might be slightly different; but their shape has yet to change. Well, guess what! AU Fins has changed the status quo! We’ve risked it all to introduce the 24K & Signature Series models to the surfing world.
*The 24K Gold Flake version offers a reinforced blend of carbon fiber in the lower half of the fin that deflects energy from the solid base to the flexible tip. This energy has a recoil effect when combined with our patent-pending AU signature curve, it creates what we refer to as “Spiral Propulsion Technology”.
*The Carbon Black Gold version has an upright tip for tighter, straight up and down turns. They are suited to beach breaks and fast waves that require quick snappy turns. Ideal for the days that you need an easy release or just need to blow out the tail above the lip.
