{"product_id":"duotone-fin-f_ride-tuttle","title":"Duotone Fin F_Ride (Tuttle)","description":"\u003cp\u003eDuotone accessible speed — finally within reach. Born from more than 20 years of freeride and race fin development by designer Dani Aeberli, the F_RIDE (TUTTLE) brings true free-ride\/race excitement to every single session. Designed for riders who want one fin that truly does it all, the F_RIDE (TUTTLE) delivers explosive speed, smooth and predictable manoeuvrability, rock‑solid control, and exceptional stability. Whether you’re accelerating, carving clean jibes, or pushing your personal limits, this fin gives you the confidence to sail harder, faster, and with more control. Its medium rake provides a forgiving upwind feel and dramatically reduces spinouts — whether in light winds, gusty conditions, or fully overpowered. Built using Molded Prepreg Technology — the most advanced and most expensive fin construction available — the F_RIDE (TUTTLE) features individually oriented carbon layers for perfectly tuned flex and maximum reflex. This is premium engineering you can feel on the water. The F_RIDE (TUTTLE) is your gateway to the faster disciplines, from freerace to early‑stage slalom, helping you progress without your gear becoming the limiting factor. With its balanced flex, consistent lift, and seamless acceleration, it pairs perfectly with any freeride or freerace board — so you can focus on pure sailing joy, not on fighting your equipment.\u003c\/p\u003e\u003cp\u003eThis Duotone fin is designed for precise control, grip, and reliable performance in demanding windsurfing conditions.\u003c\/p\u003e\u003cp\u003eOrder today from Worthing Watersports – the UK’s Duotone specialist store\u003c\/p\u003e\u003ch3\u003eTech Features\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eTWIST DESIGN:\u003c\/strong\u003e Medium twist for balanced behavior between manoeuvrability, control, upwind performance and speed.\u003cbr\u003e\u003cstrong\u003eFLEX DESIGN:\u003c\/strong\u003e Medium flex tip for balanced behavior between manoeuvrability, control, upwind performance and speed.\u003cbr\u003e\u003cstrong\u003ePrepreg:\u003c\/strong\u003e This is the most sophisticated method of manufacturing a fin. It is based on individual pre-impregnated (prepreg) fiber layers out of carbon and glass. These layers consist of single fibers that are laid side by side onto a carrier film and then pre-impregnated with resin by a specialized supplier in an industrial hydraulic press. This ensures the ideal ratio between fibers and resin (not too much, to avoid excessive weight and ensure a perfect bond between the layers, and not too little, to avoid dry spots that can lead to breakage) even before it is further processed by our factory. For these reasons, prepreg fins are at least 50% stronger in terms of breaking strength than the standard\/conventional RTM technology, which uses dry fibers with \"uncontrolled\" resin addition. Advantages:\u0026gt; Flex and twist are not only determined by the length, width, and profile thickness of the fin design (as with G10 fins), but can also be adjusted by the arrangement of the prepreg layers.\u0026gt; Lighter than G10. Best suited for:Prepreg fins are ideal for longer high-performance fins from freeride up to racing.\u003cbr\u003e\u003cstrong\u003eOUTLINE DESIGN:\u003c\/strong\u003e Only slightly curved leading edge with a focus on speed, control, and performance. The increased curve at the tip provides a certain twist and flex for excellent manoeuvrability when jibing.\u003cbr\u003e\u003cstrong\u003ePROFILE DESIGN:\u003c\/strong\u003e Performance-oriented profile, with the max profile depth at around 34-36% (depending on the length) for maximum performance efficiency and speed over a wide wind range.\u003cbr\u003e\u003cstrong\u003eBASE DESIGN:\u003c\/strong\u003e Super stiff fin base for most direct power transmission.\u003cbr\u003e\u003cstrong\u003eAI_Fin_3D:\u003c\/strong\u003e Our software is based on math data-driven input. Apart from being much more accurate and faster, complex 3D design tasks such as the perfect profile transition in the crucial tip area, where the fin sweeps backward, would otherwise have been impossible to realize. This allows us to cross-check the outcome using artificial intelligence to ensure maximum precision. This is the key secret behind the outstanding efficiency of our fins.\u003cbr\u003e\u003cstrong\u003eTWIST DESIGN:\u003c\/strong\u003e Blocked twist for increased lift, instant acceleration and max. performance.\u003c\/p\u003e\u003ch3\u003eBrand Video\u003c\/h3\u003e\u003ciframe width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/sqkGIG_n\" title=\"YouTube video player\" frameborder=\"0\" allowfullscreen\u003e\u003c\/iframe\u003e\u003ch3\u003eTech Spec\u003c\/h3\u003e\u003ctable\u003e\n\u003cthead\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFIN\u003c\/td\u003e\n\u003ctd\u003eF_RIDE (TUTTLE) 34\u003c\/td\u003e\n\u003ctd\u003eF_RIDE (TUTTLE) 38\u003c\/td\u003e\n\u003ctd\u003eF_RIDE (TUTTLE) 42\u003c\/td\u003e\n\u003ctd\u003eF_RIDE (TUTTLE) 44\u003c\/td\u003e\n\u003ctd\u003eF_RIDE (TUTTLE) 46\u003c\/td\u003e\n\u003ctd\u003eF_RIDE (TUTTLE) 48\u003c\/td\u003e\n\u003ctd\u003eF_RIDE (TUTTLE) 48\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLENGTH (CM)\u003c\/td\u003e\n\u003ctd\u003e34.0\u003c\/td\u003e\n\u003ctd\u003e38.0\u003c\/td\u003e\n\u003ctd\u003e42.0\u003c\/td\u003e\n\u003ctd\u003e44.0\u003c\/td\u003e\n\u003ctd\u003e46.0\u003c\/td\u003e\n\u003ctd\u003e48.0\u003c\/td\u003e\n\u003ctd\u003e50.0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBOX SYSTEM*\u003c\/td\u003e\n\u003ctd\u003eTUTTLEBOX\u003c\/td\u003e\n\u003ctd\u003eTUTTLEBOX\u003c\/td\u003e\n\u003ctd\u003eTUTTLEBOX\u003c\/td\u003e\n\u003ctd\u003eTUTTLEBOX\u003c\/td\u003e\n\u003ctd\u003eTUTTLEBOX\u003c\/td\u003e\n\u003ctd\u003eTUTTLEBOX\u003c\/td\u003e\n\u003ctd\u003eTUTTLEBOX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTECHNOLOGY\u003c\/td\u003e\n\u003ctd\u003ePREGREP CARBON\u003c\/td\u003e\n\u003ctd\u003ePREGREP CARBON\u003c\/td\u003e\n\u003ctd\u003ePREGREP CARBON\u003c\/td\u003e\n\u003ctd\u003ePREGREP CARBON\u003c\/td\u003e\n\u003ctd\u003ePREGREP CARBON\u003c\/td\u003e\n\u003ctd\u003ePREGREP CARBON\u003c\/td\u003e\n\u003ctd\u003ePREGREP CARBON\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDESIGNER\u003c\/td\u003e\n\u003ctd\u003eDANI AEBERLI\u003c\/td\u003e\n\u003ctd\u003eDANI AEBERLI\u003c\/td\u003e\n\u003ctd\u003eDANI AEBERLI\u003c\/td\u003e\n\u003ctd\u003eDANI AEBERLI\u003c\/td\u003e\n\u003ctd\u003eDANI AEBERLI\u003c\/td\u003e\n\u003ctd\u003eDANI AEBERLI\u003c\/td\u003e\n\u003ctd\u003eDANI AEBERLI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eREC.
