The Armstrong Pump Foil (APF)

This range redefines pump foiling potential with its ultra-low stall speeds, incredible stability and high efficiency to take you further with less effort than ever.

• EASY TO FLY WITH ULTRA-LOW STALL SPEEDS
• PITCH STABLE TO HELP YOU BUILD A NATURAL PUMPING CADENCE
• CO-DESIGNED WITH AEROSPACE ENGINEER CHRIS PORTER

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 optimized for exploring flat water or cruising effortlessly on micro bumps.

Set up for rock solid stability

The APF delivers pitch stability in key phases off light without completely sacrificing sensitivity and maneuverability for expert riders.The specially designed high camber Pump 202 stabilizer 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.

Designed with Chris Porter

Designed in collaboration with career aerospace engineerChris Porter, the APF foil shares its DNA with his reputed Crisp 333 and 381 stabilizers. Our approach to finding gains across all areas of the foil design have led to a pump foil that’s truly designed from tip to tip for the discipline

A New Addition to the APF Family

APF design DNA distilled into a smaller size.

The APF (Armstrong Pump Foil) foils have redefined pump foiling potential since their release last year. The new APF 1350 fills the space between the APF 1675 and HA 1180. It’s ideal for lighter riders chasing pump foiling or learning to downwind, or riders of any weight seeking the low-speed takeoff of the APF but with more speed and glide than an APF 1675.

Best of both worlds

Ultra-low stall speed with the performance to glide at speed.

The APF 1350’s design DNA is rooted in what makes the APF foils so good at low speeds – a straight leading edge and high camber foil section – and benefits from the latest research and design that went into our HA foils. Like the larger APFs, the 1350 foil section gives it a very low stall speed with excellent low speed controllability and predictability. The outer portion of the foil shares its section design with the HA foils to achieve a greater average glide speed and efficiency.

Rock Solid Stability

Stable when you need it, responsive when you want it.

The APF 1350 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. This solid feeling underfoot lets you focus on building your technique and developing efficiency to go further than ever before.

World Class Design

When a foil mastermind and aerospace engineer combine.

Collaboratively designed by Armie Armstrong and 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 a pump foil that’s truly designed from tip to tip for performance and user friendliness.

A+ System

The ultimate modular foil assembly system

The A+ System is our proprietary foil assembly design that joins the mast, fuselage, front foil and stabiliser together for a solid and smooth feeling on the water.

– Hexagonal carbon fibre fuselage with a titanium rod core creates a uniquely smooth feel underfoot.

– Premium 316 steel and titanium hardware eliminates corrosion and provides a naturally snug fit, no tef gel required.

– Polycarbonate Pro shims allow for half degree incremental changes to stabiliser pitch for incredibly easy tuning of the foil’s flight characteristics.

Features

• High aspect ratio: 10.7 AR for excellent glide efficiency.
• High camber section: Creates a low stall speed with excellent low speed controllability and predictability.
• Rounded safety wing tips: For safety in case of a fall onto the wing tip.
• Toray carbon fibre: Built from premium Toray high and intermediate modulus carbon fibre for exceptional stiffness and light weight.
• Armstrong A+ System: Our proprietary connection system offers industry-leading strength, durability and modularity.
