The Harley Ingleby Series Surfboards brings together the shaping prowess of legendary board builder Billy Tolhurst and the innovative Thunderbolt tech of forward-thinker Yu Sumitomo to create high-tech boards designed by and for two-time world champion Harley Ingleby. The Harley Ingleby Series is the apex of longboard evolution—proven, high-performance shapes with the lightweight strength and flex characteristics of a proprietary, space-age construction process combining hand layups, EPS cores, and targeted carbon fiber elements.
