Armstrong Alloy System Mast

The Armstrong Alloy System Mast is an aluminum foil mast offered in three lengths as part of Armstrong's modular Alloy System. Introduced as a more affordable alternative to Armstrong's carbon Performance Mast range, the Alloy System Mast draws on the same profile and structural knowledge developed for that carbon lineup. It pairs exclusively with Armstrong's Alloy fuselage components and ships with a mast cover included. The mast is available in 58 cm, 72 cm, and 85 cm lengths, giving riders flexibility to match mast height to their skill level and riding conditions.

Armstrong engineered the mast section at 17.5 mm thick — thin enough to move through water efficiently while remaining robust under the loads generated during higher-performance riding. The top plate and bottom bracket are machined separately and draw design cues from SailGP foiling hardware, using aerospace-grade aluminium to maintain tight tolerances.

• Material: Aircraft-grade 6061 and 7075 aluminium alloy
• Mast section thickness: 17.5 mm
• Weight (72 cm): 2.9 kg complete
• Available lengths: 58 cm, 72 cm, 85 cm
• Hardware: Titanium and surgical stainless steel; custom M7 and M8 × 1.25 screws
• Includes: Mast cover

Armstrong positions the Alloy System Mast for riders across the skill spectrum — from beginners stepping onto a foil for the first time to intermediate and advancing riders who want a durable, corrosion-resistant setup without the price of carbon. The shorter 58 cm length suits newer foilers who benefit from a lower ride height and quicker recovery when learning, while the 72 cm and 85 cm options give progressing and experienced riders more clearance for chop and swell.

Because the Alloy System is fully compatible with all Armstrong front wings and stabilisers, a rider can start on a larger, more forgiving wing and swap to smaller, faster foils as ability grows — all on the same mast and fuselage. The titanium and stainless hardware is chosen for long-term saltwater durability, making the setup practical for riders who want low-maintenance gear that holds up season after season.

Within Armstrong's catalog, the Alloy System sits below the carbon Performance Mast range in both price and weight. The carbon masts target weight-sensitive riders chasing outright performance, while the Alloy System prioritises durability, value, and ease of ownership. Both systems share the same wing and stabiliser compatibility, so upgrading from alloy to carbon later requires only swapping the mast and fuselage rather than replacing an entire foil.

The Alloy System Mast competes in a growing segment of aluminium foil masts aimed at entry-to-intermediate riders. Comparable options include the Slingshot Hover Glide aluminium mast and the Naish Jet alloy mast, both of which occupy a similar price bracket and target a similar progression-oriented audience. Armstrong differentiates primarily on its modular component ecosystem and the use of mixed 6061/7075 alloys with titanium hardware at this price point.
