I’m honored to be among the first to test a groundbreaking new prototype racing prop designed by Jeff Argov at —and I can confidently say this prop is a true game changer for efoil racing. On my Ultra, I’ve gained several miles per hour of top-end speed, with smoother acceleration through high-G turns and noticeably less flex at full power. The balance is dialed in too—minimal added front-foot pressure, responsive handling, and unmatched consistency lap after lap. While proper form, a shortened tail piece, and correct shimming are still key, this prop gives racers a massive edge in performance and control. I couldn’t be more excited for what this means for the future of competitive efoiling.
