The Alloy System

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 of all levels 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.
