The F-ONE MOMENTUM is a state-of-the-art downwind foil range, engineered specifically for elite downwind SUP and wing foiling. Tailored for experts and downwind fanatics who demand infinite glide and extended flight time in the open ocean, the MOMENTUM is a proven competition winner—most notably securing victory at the prestigious 2024 Moloka’i to O’ahu (M2O) race. With a radical Aspect Ratio (AR) of 16.5, this foil is designed to harvest every ounce of energy from the swell, allowing riders to glide faster and for longer than ever before, even in the smallest bumps.

Precision and rigidity are central to the MOMENTUM’s performance, featuring a specialized Ultra High Modulus (UHM) Carbon construction. This advanced layup is 1.2x stiffer than standard High Modulus carbon, providing the instant feedback and control required to manage a profile this thin and high-performing. The foil utilizes F-ONE’s Monobloc structure, molding the front wing and fuselage together as a single piece to eliminate flex and maximize hydrodynamic efficiency. Whether you are racing across technical open-ocean channels or seeking the ultimate pumping efficiency for flat-water starts, the MOMENTUM delivers unmatched speed, stability, and finesse for the most demanding riders.

Expert Advice: The MOMENTUM is F-ONE’s ultimate downwind weapon for riders looking to cover massive distances. In UK waters, where we often deal with fast-moving but low-period wind bumps, the 16.5 AR is a genuine revelation—it stays "on foil" through sections that would stall other wings. For most UK experts, the 716 or 816 sizes are the real sweet spot, offering enough lift to get flying in our typical conditions while maintaining the top-end speed needed for downwind racing. We highly recommend pairing this with the XS 135 DW Monobloc tail to truly maximize the glide and stability of the rig.
