Achieve maximum time on foil
If you’re just learning or already seasoned, a forgiving foil that helps keep you flying makes all the difference when building your pumping skills. The APF’s outline shape, straight leading edge and high camber foil section offer ultra low stall speeds, quick acceleration and a relaxed, efficient pumping cadence optimised for exploring flat water or cruising effortlessly on micro bumps.
Set up for rock solid stability
The APF delivers pitch stability in key phases of flight without completely sacrificing sensitivity and manoeuvrability for expert riders. The specially designed high camber Pump 202 stabiliser works in harmony with the APF to provide excellent pitch stability throughout the entire pump cycle. This solid feeling underfoot lets you focus on building your technique and developing efficiency to go further than ever before.
