Armstrong S1 Alloy Mast

Armstrong S1 Alloy Mast

Modularity is core to the Alloy System design. It’s fully compatible with all Armstrong front foils and stabilizers so as riders’ style evolves, so can their setup. Building on the knowledge and technology that led to Armstrong's industry-leading carbon Performance Mast, the AA mast shape and structure are optimized 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 aluminum alloys.

Note: Mast only. Bottom Bracket, Top Plate, and Hardware set are required for a complete setup

Features

• 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.
