Design

Precision in every dimension

The Performance-X’s section is all about minimal resistance, maximum flow. With a 106.8mm chord and just 12mm of thickness, it delivers a lighter, looser feel in the water, especially noticeable when laying into turns. The Performance-X has been engineered to thrive at these dimensions, letting you work with the foil's forces, not against them.

Materials

Ultra-High Modulus Efficiency

Built from ultra-high modulus carbon, the Performance-X Mast 12mm pushes the limits of what’s possible in layup engineering. This next-gen material unlocks a significantly thinner profile without compromising weight, stiffness, or feel. The result? Reduced drag, increased glide, and a structure that stays predictable and keeps the Armstrong feeling.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.
