Armstrong A+ System 795mm Integrated Foil Drive Carbon Mast

The Armstrong A+ System 795mm Integrated Foil Drive Carbon Mast is a purpose-built carbon mast designed to house Foil Drive motor systems directly within the mast structure, eliminating the external clamps, wiring, and electrical tape associated with aftermarket motor installations. Developed as a collaboration between Armstrong Foils and Foil Drive, this mast uses the same Toray high-modulus carbon fiber layup found in Armstrong's standard Performance Carbon Mast line, maintaining the stiffness and feedback characteristics riders expect from Armstrong's flagship construction. The mast is part of the A+ System, Armstrong's proprietary assembly interface that joins the mast, fuselage, front wing, and stabilizer through a hexagonal tapered fit.

The mast ships in two pod-height configurations: a 185mm pod position oriented toward foil-assist disciplines (wing foiling, surf foiling, prone foiling with motor-assisted takeoffs), and a 650mm pod position designed for full-time e-foil use where the motor remains submerged during riding. Both configurations share the same 795mm mast length and carbon construction.

• Mast length: 795mm
• Construction: Toray high-modulus carbon fiber (Performance Mast layup)
• Assembly system: A+ System (hexagonal tapered fit)
• Pod height options: 185mm (Foil Assist), 650mm (E-Foil)
• Motor compatibility: Foil Drive V2 motors (Standard and High Power)
• Hardware included: Protective cover, T30 Torx tool, puck hardware (M4/M5 titanium), mast-top hardware (M8 titanium), mast-bottom hardware (M6 titanium barrel nut)
• Sold separately: Motor, battery, 4x M7 79mm titanium mast-top screws, 4x titanium T-nuts

This mast targets riders already invested in the Armstrong foil ecosystem who want to add Foil Drive motor assist without compromising their setup's hydrodynamic profile. The 185mm Foil Assist configuration suits wing foilers, surf foilers, and downwind riders who use the motor primarily for takeoffs, repositioning, or getting back upwind — disciplines where the motor retracts above the waterline during active foiling. Armstrong positions the 185mm pod height as the general-purpose option that balances low drag with stable motor engagement across conditions.

The 650mm E-Foil configuration is aimed at riders who want continuous powered foiling, with the motor pod positioned for full-time submersion and consistent thrust delivery. Both variants assume intermediate-to-advanced foiling ability; this is an upgrade component, not a starter setup. Riders need an existing Armstrong A+ foil package and a Foil Drive V2 motor system to complete the build.

The Integrated Foil Drive mast sits alongside Armstrong's standard Performance Carbon Mast in the A+ System range. Where the standard Performance Mast serves unpowered foiling across all disciplines, this variant adds the internal motor cavity and cable routing specific to Foil Drive integration. Both share identical carbon construction and the same A+ assembly interface, so riders can swap between powered and unpowered masts within the same foil package without changing fuselages or wings.

Within the broader integrated-mast market, Armstrong's offering competes with Foil Drive's own integrated masts built on other brand platforms, including Axis and Uni Foil integrations available through Foil Drive's product line. The Armstrong version leverages the A+ System's established reputation for assembly rigidity and the brand's extensive wing and stabilizer catalog. At $1,999.99 for either pod configuration, pricing aligns closely with other premium integrated carbon mast options in the Foil Drive ecosystem.
