Armstrong Alloy System Fuselage

The Armstrong Alloy System Fuselage is a modular aluminum fuselage designed to serve as an accessible entry point into Armstrong's foil ecosystem. Offered in 65 cm and 75 cm lengths, it uses the same front-foil and stabilizer attachment geometry as Armstrong's higher-end Titanium Core fuselage, giving riders a clear upgrade path without needing to replace wings or tails. The hexagonal cross-section of the fuselage body is engineered for stiffness and strength while keeping the front-foil swap process straightforward — a practical advantage during on-water sessions where conditions change.

Armstrong machined the Alloy fuselage from aircraft-grade 6061 and 7075 aluminum, pairing the airframe with titanium and surgical-stainless-steel fasteners (custom M7 and M8 × 1.25 screws) to resist saltwater corrosion over time. The fuselage connects to the mast through Armstrong's proprietary Bottom Bracket interface. Hardware is sold separately as the Alloy System Hardware Set.

• Material: 6061 and 7075 aircraft-grade aluminum
• Available lengths: 65 cm, 75 cm
• Mast section thickness: 17.5 mm
• Hardware: Titanium and surgical stainless steel (M7 and M8 × 1.25 screws)
• Mast interface: Armstrong Bottom Bracket
• Front foil / stabilizer compatibility: All current Armstrong front foils and stabilizers

The Alloy fuselage suits riders entering the sport or those looking for a durable, cost-effective second setup. Because it shares attachment points with Armstrong's carbon and titanium fuselages, a beginner can start here and later move to a lighter fuselage without replacing any wings. It also works well as a loaner or travel setup where ding resistance matters more than shaving grams.

The 75 cm length provides additional stability and a wider effective wind range, making it a natural choice for newer foilers or heavier riders who benefit from the extra separation between front foil and stabilizer. The 65 cm option tightens the turning radius and increases responsiveness, suiting intermediate riders progressing toward tighter carves and quicker transitions. Both lengths pair with the full Armstrong wing and stabilizer catalog, so riders can tune the setup as their skills develop.

Within Armstrong's range, the Alloy fuselage sits below the Titanium Core (TC) and A+ System carbon fuselages in both price and weight. It was introduced alongside the Step 1 (S1) foil package as part of Armstrong's push to offer a complete alloy-based kit at a lower price point — without locking buyers out of the broader component ecosystem. Riders who outgrow the alloy setup can upgrade to the A+ TC fuselage for reduced weight and increased stiffness while keeping the same wings and stabilizers.

Compared to entry-level fuselages from other brands — such as the Slingshot Hover Glide aluminum fuselage or the Cabrinha alloy fuselage options — the Armstrong Alloy fuselage differentiates itself through full cross-compatibility with Armstrong's performance-level carbon wings, letting riders scale their setup incrementally rather than replacing an entire foil package at once.
