Armstrong Foil Drive Foil Assist Integrated Carbon Mast

Seamless power assist meets signature Armstrong feel. Fully integrated, freakishly smooth.

The Armstrong Foil Drive Integrated Mast is purpose-built to bring power assist into the Armstrong ecosystem. Engineered with a forward-set motor pod for smoother lift and reduced drag, this mast delivers that signature Armstrong feel with electric acceleration and zero clutter.

Whether you're chasing bumps or waves on windless days or just starting out, this setup is your session-extender. Beginners can learn faster with powered assist. Advanced riders can chase more waves, boost recovery time, or ride spots they normally couldn’t. This is your fast track to more waves and quicker progression.

Key Features

Pod Height – the sweet spot

The 185 mm motor pod position hits the sweet spot for most foil-assist disciplines: low drag, well-balanced, and basically invisible once you’re on foil. While some advanced riders prefer to mount it closer to the board and beginners stretch it out to 220 mm for extra margin, 185 mm remains the goldilocks zone for everyday versatility.

Fully integrated for efficiency – smoother lift, lower drag

The motor pod is positioned further forward than typical integrations, reducing drag at the front end and enhancing lift from the prop. The result? Seamless acceleration and a noticeably smoother ride when powering up.

Design – industry-leading performance

This mast uses the same layup and design DNA as our industry-leading Performance Carbon Mast, meaning you get high stiffness, low flex, and ultra-precise feedback whether you’re pumping through bumps or carving through sections.

Construction – built the Armstrong way

Manufactured with Toray high modulus carbon fiber and finished to the same spec as our Performance Masts, this mast is built to handle real-world torsional loads without flinching. Premium construction meets plug-and-play practicality for Foil Drive riders.

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 stabilizer with a hexagonal tapered fit into the front foil. This design is incredibly strong, torsionally rigid, and durable when combined with our material selection. Paired with premium titanium and stainless steel hardware, corrosion is minimized and the whole package has an industry-leading fit and finish.

Features

• Forward-set Foil Drive motor pod position for reduced drag and improved lift
• Based on the Armstrong Performance Mast platform
• Super stiff carbon layup for maximum control
