Armstrong Midlength Mk II X-Form Foiloard

Armstrong Midlength Mk II X-Form Foiloard. 

The Midlength Mk II 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 II 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 around Armstrong's new X-Form Precision Molded Board Technology, the Midlength
Mk II delivers an uncompromising strength-to-weight ratio with precision-tuned
performance. Stronger, stiffer, and more durable than traditional constructions, it
maintains the connected feel Armstrong boards are known for while eliminating
softening and fatigue over time.
On the water, the Midlength Mk II feels composed, responsive, and predictable. The
thinner X-Form profile delivers a more direct connection to the foil while the refined
bottom design reduces sticking and tracking for cleaner touchdowns and faster recovery.
Combined with a surf-style squash tail, Forward Geometry foil track, integrated carbon
foil tracks, dual carbon stringer system, and redesigned deck grip, the Midlength Mk II
delivers greater control, confidence, and progression across all foiling disciplines.

Construction:
X-Form - Precision Molded Board Technology
From the beginning, Armstrong was built on a simple belief: riders should be able to
trust their equipment in the harshest conditions, every day. X-Form was born from that
same mindset. When existing manufacturing methods couldn't deliver the strength,
precision, and durability we envisioned, we didn't compromise, we built our own
purpose-designed factory. X-Form represents our commitment to doing things properly,
using precision manufacturing to create boards that are stronger, more consistent, and
built to progress with riders over time.
Why we built X-Form?
Optimal Strength to Weight Ratio.
X-Form was developed to reduce weight while solving long-standing durability and
consistency challenges, this construction delivers an uncompromising strength to weightratio with precision-tuned performance. Because performance means nothing if your
gear doesn’t last.
By eliminating the inconsistencies and long-term fatigue associated with traditional
board construction, X-Form creates boards that are lighter, stronger, more durable, and
more connected underfoot. The result is predictable performance, increased longevity,
and a direct connection to the foil that riders can feel every session.
What exactly is X-Form?
Exact Form, Every Time.
X-Form is Armstrong's precision molded board technology and manufacturing process.
Developed using proprietary CNC-machined molds, precision-engineered internal
components, and advanced composite construction, every X-Form board is formed in a
single molding cycle under uniform pressure and temperature. The process permanently
locks in the board's rocker lines, rails, bevels, and contours while ensuring every internal
component is aligned to exact tolerances. Drawing on Armstrong's experience designing
and manufacturing high-precision molded foils, X-Form brings the same level of
manufacturing accuracy and consistency to board construction.
X-Form Benefits:
More Direct Connection
The strength and precision of X-Form construction allow for a considerably thinner board
profile, creating a more direct connection to the foil. The result is cleaner feedback
underfoot, improved control, and a more responsive feel that helps riders stay
connected to what the foil is doing.
Built to Last
Designed to withstand the demands of everyday progression, X-Form delivers a
stronger, stiffer, and more durable construction than traditional board manufacturing
methods. The precision molded process helps maintain the board's structural integrity
and ride characteristics over time, reducing softening and fatigue session after session.
X-Form Features:
Foil Assist Compatible Window
Foil Assist compatible window for clean, uninterrupted remote signal.
Double Sandwich Foot Area
Complete PVC wrap of deck and underside of board with extra reinforced foot panels
which are doubled up with another layer of high density PVC to handle the heaviest of
landings.High Density PVC Wrap
Entire internal surface of board wrapped in high density PVC. Even if it does crack it
won't absorb water like EPS foam would.
High Density PVC Rails
High density PVC foam wrap of the whole perimeter of board. Protects the areas of the
board most at risk to damage.
Ultralight Large Sphere EPS Core
The high-pressure molded layup is super stiff and the ultralight EPS core absorbs shocks
for a solid and smooth ride.
Dual Carbon Stringer System
Armstrong's reputed I-beam top-to-bottom dual carbon stringers provide maximum
structural rigidity and durability by fully connecting the deck and bottom of the board.
Carbon Foil Tracks
Proprietary carbon fiber foil tracks are keyed directly into the stringer fibers along with
carbon fiber for a fully integrated and ultra-strong construction where it counts most.
Shape & Outline
Balanced, Responsive, Predictable.
On the water, the Midlength Mk II feels composed, responsive, and predictable.
The improved stiffness profile creates a clean, connected sensation underfoot, allowing
riders to feel exactly what the foil is doing. The result is more confidence at speed,
better control in critical moments, and a smoother, more intuitive riding experience
across disciplines.
Refined Profile
Thanks to the new X-Form construction the refined profile features a considerably
thinner board, delivering a more direct connection to the foil and reducing unwanted
touch-downs.
Optimized volume distribution
Optimized volume distribution maintains stability and balance while allowing the board
to sit lower to the water, creating a cleaner, more responsive feel underfoot. The result
is a thinner, more connected board that enhances control, feedback, and confidence
across all conditions.
Reduced Sticking & Tracking
The new bottom design is shaped to optimize fluid dynamics at every phase of flight.
A refined double concave transitioning to a subtle V helps generate early lift, making
take-offs easier and more efficient while smoothing touch-downs.When the board reconnects with the water, it glances off the surface rather than
sticking or tracking, allowing for quick, clean release back onto foil. Shallower chines
and a flatter bottom through the rear further reduce drag and resistance, creating a
fast, predictable feel that supports take-offs and landings.
Surf Style Squash Tail
The surf-style squashed tail adds stability when getting onto the board, making early
positioning and balance more intuitive. By allowing the rails to remain more parallel for
longer, the shape increases surface efficiency and helps generate speed quickly,
improving take-off performance. The result is a tail design that feels stable underfoot
while delivering faster, more confident launches onto foil.
Forward Geometry Foil Track
Armstrong's Forward Geometry concept, introduced in 2021, redefined foilboard design
by placing the foil more centrally to reduce swing weight and increase responsiveness
while remaining compatible with any foil system. The Midlength Mk II continues this
legacy with FG foil tracks positioned further forward for enhanced maneuverability and a
more connected feel on foil across all board sizes.
Deck grip
More Grip, More Control
The new Midlength Mk II deck grip is designed to reduce weight while increasing grip
and control underfoot. Despite the lighter construction, it maintains Armstrong's
signature soft feel, providing comfort and confidence for riders learning new skills, using
Foil Assist, or spending extended sessions on an e-foil.
Deck Grip Features:
• Dual Foot Arch Bars - Intuitive foot positioning.
• Rear Foot Wedges - Intuitive foot positioning relative to mast position.
• Foil Track Indicators - For foot positioning relative to mast position.
• Triangle Cut Outs - Reduce weight and increase grip.
