The Duotone Foil Assist 3-Blade SLS Propeller has landed — the most powerful propeller option in the Foil Assist range, built to unlock more thrust, faster acceleration and higher top speeds for advanced and heavier riders (80kg+). We put all three propeller options through a proper back-to-back test in real UK winter conditions, riding the Duotone Mid Fish with a Crest 925 front wing, and the results were clear: propeller choice comes down to rider weight, not headline power. The aluminium 3-blade design delivers serious thrust and earlier take-off for the right rider, while the 2-Blade SLS remains the all-round sweet spot for most. Read our full comparison of the 2-Blade Regular, 2-Blade SLS and new 3-Blade SLS propellers to find the right match for your weight, foil size and riding style.
