The Mach 7-7 introduced a radical, new concept: the "ion speed" slick bottom. Its groundbreaking design forever changed the face of bodyboarding, offering unprecedented speed (especially as compared to other boards of the era) and ushering in a whole new generation of high tech bodyboards with slick bottoms. Only produced for two years, the first generation Mach 7-7 featured 70/30 rails and a black bottom. The black bottom was prone to bubbling and was later changed to the more familiar orange color. Photo: Henry Marfleet.
