Finn and Jeffery Spencer are more than standout athletes – they’re key drivers of Duotone’s Wing & Foiling R&D and board shaping. Raised on Maui, the brothers blend elite riding with daily water time and deep product insight. From designing boards to testing wings and foils, they play a vital role in developing high-performance gear across all disciplines: Wing, Surf, Downwind, and Pump Foiling.
Finn and Jeffrey Spencer are not just top riders; they play an enormous role in Duotone’s Research & Development (R&D) process –now and in the future. The Hawaiian-born brothers are at the forefront of shaping the future of Duotone Wing & Foiling. Their experience and test feedback not only helps to fine-tune our wings and foils, but they are also in charge of our board designs for Wing Foiling, Surf Foiling, Downwind Foiling and PumpFoiling. With their enormous product knowledge and foiling skills,they are ensuring every product meets the demands of our customers, from newbie to the highest performing riders. As athletes they are also competing in the GWA wave circle and have the chance to constantly test new gear in different conditions to those in their Hawaiian home waters. These firsthand insights contribute to groundbreaking innovations like the Skybrid mid-length boards, the Crushprone foilboard or our Float wave wing. The ability to analyze and push prototypes to the edge right in front of their home on Maui allows us to create some of the most advanced foiling gear on the market.
Finn and Jeffrey ́s product feedback directly influences our design work, and they are working very closely together with our wing designer Ken Winner(who is also based on Maui), our foil designer Jerome Bonieux as well as our Duotone R&D office team with Klaas Voget, Max Pajank and Alex Held.
Finn and Jeffrey were born in Canada, but moved to Hawaii as babies. Growing up in the powerful surf of Maui, the brothers always had a natural connection to the ocean from a very young age. They quickly became pioneers in the foiling scene, from Wing Foiling to Downwind Foiling and Surf Foiling and their effortless style impresses everyone. They are are a source of inspiration for many aspiring younger foilers and lots of our Duotone Wing & Foiling Young Blood riders.
With always new prototypes in the works and the latest advancements in Wing & Foiling technology, the Spencer brothers continue to design, test, refine, and innovate. Whether they’re charging massive swells, racing at top speeds, or working on the next innovative design, one thing is certain: Finn and Jeffrey Spencer are shaping the future of Duotone Wing & Foiling.
With this video we would like to share some insights from Finn and Jeffrey Spencer, and their journey towards the future of Wing & Foiling R&D.
