Connected Performance

The Midlength Mk Il marks the next step forward in Armstrong's board design, debuting our all-new molded board technology. Built to deliver a lighter, stronger, and more connected ride, it represents a major leap in durability, response, and long-term performance.

Refined through years of testing in New Zealand's most demanding conditions, the Midlength Mk Il blends Armstrong's signature feel with a new level of control and consistency. It's designed not just to perform, but to keep performing session after session.

Built Stronger. Ride It Longer

The Midlength Mk II introduces a new approach to board construction, focused on long term performance and durability.

The molded process ensures every board is produced with consistent shape, flex, and strength, while significantly increasing stiffness and reducing weight. The result is a board that not only performs at a high level but maintains that performance over time.

Direct Connection

A thinner profile combined with increased stiffness brings riders closer to the foil, creating a more immediate and responsive feel.

Energy transfer becomes faster and more efficient, improving control through turns, smoother transitions, and more stable recoveries. The board feels smaller and more agile without sacrificing volume or stability.

Light Where It Matters

Reduced swing weight transforms how the board moves. It feels lighter in motion, easier to control through direction changes, and more responsive during pumping and manoeuvres.

This lighter, more agile feel allows riders to progress with confidence, while maintaining the stability expected from a midlength platform.

Pure Strength Construction

At the core of the Midlength Mk II is a construction built for real world use.

With multi density PVC rails, reinforced standing areas, dual carbon stringers, and integrated carbon foil tracks, every element is designed to handle repeated stress without fatigue or softening.

It is a board built to last, without compromising performance.

Calm, Connected Ride

On the water, the Midlength Mk II feels composed and predictable. The increased stiffness delivers a clean, connected sensation underfoot, allowing riders to stay fully in tune with the foil.

Touchdowns release cleanly, takeoffs feel efficient, and control at speed is improved. The result is a smoother, more intuitive riding experience across a wide range of conditions.
