Armstrong S1 Alloy Mast

One system, endless possibilities.

The Alloy System was designed to enable riders of all skill levels to chase endless experiences on the water. Its modularity, broad performance range and exceptional build quality empowers riders to progress without limits.

Modularity is core to the Alloy System design. It’s fully compatible with all our front foils and stabilisers so you as your riding evolves, so can your setup. Building on the knowledge and technology that led to our industry-leading carbon Performance Mast, the AA mast shape and structure are optimised from top to bottom for an excellent balance of efficiency and strength. This approach to design and attention to detail is exemplified in the Alloy System’s specially machined mast top and SailGP-inspired bottom bracket that are crafted from aerospace-grade aluminium alloys.

The system is outfitted exclusively with premium titanium and surgical stainless hardware for a light and highly corrosion resistant setup that’s durable over time. Industry-leading manufacturing tolerances make for a high performance, beautiful fit and finish overall.


Details

• Hexagonal fuselage shape is inherently strong, stiff and modular for an easy front foil swap.
• The mast section is 17.5mm thick; efficient through the water, yet strong to withstand the loads of advanced riding.
• Aircraft-grade 6061 and 7075 alloys for excellent strength to weight ratio.
• Titanium and stainless hardware save having to disassemble frequently so it’s easy to use and maintain with excellent corrosion resistance. Screws are custom-made M7 and M8 x 1.25.
