The One-Lock Aluminum Mast is the lightest aluminum mast on the market. Constructed with 6061 grade aluminum, the design optimizes aluminum placement for maximum weight savings and stiffness. The mast’s chord sits at 118mm, achieving a perfect balance between efficiency, stiffness and weight. This combination delivers direct and precise feedback. At the mast’s foot, our optimized One-Lock collar enhances efficiency and minimizes drag by ensuring smooth water flow from the front wing to the stabilizer, all while holding true to our durability standards. The mast also includes our RTS foil board mounting kit, which dramatically simplifies setup. Once the mast’s position is set, you can fully assemble and disassemble your foil in under 30 seconds, without the need for tools.
