The A+ System is our proprietary foil assembly design that joins the mast, fuselage, front foil and stabilizer together for a solid and smooth feeling on the water. Built to handle the progression of modern foiling, it delivers exceptional stiffness, durability, and compatibility across disciplines.
A+ was engineered for long-term ecosystem compatibility. It supports multiple fuselage lengths, cross-discipline mast use, and seamless integration as foil ranges evolve. Designed for easy disassembly and compact travel packing, it enables progression without breaking compatibility.
The A+ System HEX connection was designed to maximize strength and precision without extra weight. Its 6 sided design increases surface contact, spreads load evenly and reduces stress points. The strongest design, built to fit any foil, so you can start on Alloy, upgrade your mast and keep your foils.
The A+ System comes completely apart, allowing every component to pack down individually for efficient travel and storage. Masts, fuselages and wings separate cleanly, meaning no oversized bags, no complicated airline check-in conversations and no compromise on performance when you arrive.
The A+ System pairs titanium hardware with a reinforced fuselage spine and bolt mast connection to maximize stiffness, spread load evenly and deliver clean, reliable power transfer under high load.
Titanium and 316L stainless hardware work together for maximum stiffness and minimal movement. The result is clean power transfer from mast to foil, even in heavy loading.
At the heart of A+System is a titanium internal spine integrated into the fuselage. Titanium manages compression and shear loads while carbon maintains stiffness and hydrodynamic shape, creating a structure that behaves like a single beam. The result is reduced flex under load, cleaner power transfer, and a more direct feel underfoot.
Dual bolts for a more secure connection, increasing torsional stiffness and delivering greater control at speed. Confidently handling the torque of modern high aspect wings.
The A+ System is built with ultra precise tolerances, With a topologically optimized connections and HEX connection,for locked-in feel and immediate feedback under load. it delivers a lighter, stronger that maximises durability without unnecessary bulk.
Engineered with tight tolerances that hold firm under load. Each join locks down with a crisp, responsive feel that gives riders immediate feedback on the water.
Within the A+ System, the mast top and fuselage sleeve have been topologically optimized to add strength where loads are highest and remove material where it is not needed. Paired with the HEX connection, this creates a smarter, lighter and stronger interface with cleaner hydrodynamics and long-term durability, without unnecessary bulk.
The Armstrong Feeling is our signature freeride experience flowy, intuitive, and predictably smooth. It’s where elite performance meets easy control, giving you the confidence to push harder while making every session feel effortless.
