The Armstrong APF 1675 and 1880 are the original pump foil specialists — Armstrong's purpose-built pump foiling wings designed for ultra-low stall speeds, exceptional pumping efficiency, and the kind of long flatwater pump sessions that redefined what's possible in light wind and small swell. Two front wing sizes: the APF 1675 for most pump foilers up to ~90 kg seeking the perfect balance of pump efficiency and usable performance, and the APF 1880 for heavier riders or those wanting maximum low-end lift and pump endurance. Both kits at £1,859 include the front foil, 72 cm alloy mast, TC60 fuselage, the purpose-designed Pump 202 stabiliser, hardware, and an extra-large kit carry bag. The Armstrong A+ System makes them fully compatible with the wider Armstrong foil ecosystem. Free UK postage.

Pump Foil Specialists

Product overview

The APF (Armstrong Pump Foil) foils have redefined pump foiling potential with ultra-low stall speeds, incredible stability and high efficiency to take you further with less effort than ever.

The APF's design DNA is rooted in efficient performance at low speeds thanks in part to a straight leading edge and high-camber foil section. The foil section gives the APF a very low stall speed with excellent low-speed controllability and predictability to go further in flatwater pumping or light downwinding.

Stable when you need it, responsive when you want it. The APF delivers pitch stability in key phases of flight and a quick response to pitch inputs for zippy acceleration when you want it. The specially designed Pump 202 stabiliser works in harmony with the front foil to support flight speeds throughout the pump cycle.

Key features

Designed by Armie Armstrong & Chris Porter. Collaboratively designed by Armie Armstrong and aerospace engineer Chris Porter, the APF foils are the brainchild of their collective foil knowledge and design prowess. Chris and Armie's approach to innovating and optimising all areas of the APF's design have led to pump foils that are truly designed from tip to tip for performance and user friendliness.

Ultra-low stall speed. The foil section gives the APF a very low stall speed with excellent low-speed controllability and predictability to go further in flatwater pumping or light downwinding.

Pump 202 stabiliser (standard). Cutting-edge pumping performance to complement the APF front foil range. The Pump 202 is designed specifically to complement the Armstrong Pump Foil (APF) front foil range — engineered for pump efficiency at the speeds the APF 1675 and 1880 like to fly.

A+ System compatibility. Proprietary Armstrong A+ System foil connection design offers industry-leading stiffness, durability and modularity. The APF kit is fully compatible with the wider Armstrong foil ecosystem.

Honest advice from us

The APF range is for committed pump foilers and downwinders — these aren't beginner foils (S1 is the answer for that) and they're not the most carving-friendly foils (the HA or MA MkII handle that better). The APF wings exist to deliver one thing brilliantly: maximum pump efficiency and the lowest stall speeds in the Armstrong range.

Which APF size? The 1675 is the recommended starting size for most pump foilers — broad usable range, suits riders from beginner pump foilers through advanced. Most riders should start here. The 1880 is for heavier riders over 90 kg or experienced pump foilers under 90 kg who want maximum low-end lift and pump endurance. If you weigh under 80 kg and want pump foiling with more glide than the 1675, also consider the APF 1350 (separate kit) which we also stock.

The Pump 202 stabiliser that ships with this kit is the right call — designed specifically alongside the APF range to work at the speeds these foils like to fly.

About Armstrong

Armstrong is a New Zealand foil company founded by Armie Armstrong, a pioneering windsurfer and watersports innovator. Armstrong's modular A+ System has set the industry standard for foil compatibility — front wings, masts, fuselages and stabilisers all interconnect across the Armstrong range, meaning riders can progress from S1 (Step 1) beginner foils through to HA (High Aspect) racing foils without replacing their mast or board fittings. Built in Thailand at Armstrong's own facility, designed in New Zealand, ridden by world-class athletes including Austin Tovey, Noah Flegel and Annie Reickert.
