The Armstrong Midlength FG Mk II 2026 is a major step in Armstrong board design and introduces the new X-Form technology (Precision Molded Board Technology). Lighter, stiffer and more directly connected to the foil, it is a big leap in durability, responsiveness and lifespan. Refined for years in the demanding conditions of New Zealand, the Midlength Mk II pairs the signature Armstrong feel with a level of control and consistency we haven't seen before. It comes in 9 sizes from 4'8-inch (38 L) to 7'2-inch (130 L) and covers every discipline: Wing Foil, Prone, Foil Assist and SUP Foil.

DETAILED DESCRIPTION
X-Form: Precision Molded Board Technology
Armstrong developed X-Form technology (Precision Molded Board Technology) to cut weight while solving the durability and consistency challenges of board manufacturing. Every Midlength Mk II is formed in a single cycle, under uniform pressure and temperature, with zero distortion. Rigid proprietary CNC molds and internal parts machined to exact tolerances mean every board comes out identical: the intended behavior is preserved and performance is predictable from one session to the next.
Reinforced Dual Carbon Stringer construction
The entire inside of the board is wrapped in high density PVC: even if it cracks, water isn't absorbed the way it is with a standard EPS. The Large Sphere EPS core is molded under high pressure for maximum stiffness, while the HD PVC wrap rails protect the most exposed areas. The foot zone is backed by an extra PVC panel to take the hardest landings. The i-beam Dual Carbon Stringers tie the deck to the bottom for absolute structural stiffness, and the carbon foil tracks are keyed straight into these stringers for a perfectly integrated build.
Refined X-Form profile, direct connection to the foil
Thanks to the new X-Form construction, the refined profile of the Mk II gives a much more direct connection to the foil and drastically cuts unwanted touch-downs. Volume distribution is tuned to keep stability and balance while sitting the board lower on the water. The result: a sharper, more connected feel, with more feedback and confidence in all conditions.
Underside design, squash tail & Forward Geometry
The new bottom combines a subtle double concave running into a V at the back, for early lift, smoother touch-downs and a clean foil release. Softer edges and a flatter section at the back reduce drag. The surf-style squash tail adds stability right from the start and keeps the rails parallel for longer, which speeds up acceleration. Forward Geometry sets the foil tracks further forward to lower swing weight and improve handling, while staying compatible with any foil brand.

FAQ, ARMSTRONG MIDLENGTH FG MK 2 2026
The Midlength Mk II is an allround board designed by Armstrong for intermediate to expert riders who want a single board that covers several disciplines: Wing Foil, Prone Foil, Foil Assist and SUP Foil (on the large sizes). Its surf-inspired midlength outline is a good balance of glide, stability and handling.
The Mk II introduces the new X-Form construction: precision CNC molding in a single cycle, under uniform pressure and temperature, with proprietary rigid molds (unlike flexible fiber molds that can warp). According to Armstrong, it has a noticeably thinner profile and is stiffer, more durable and lighter at the same volume, with a more direct connection to the foil. The range also grows with two extra sizes (115 L and 130 L) that the Mk I doesn't have.
The choice depends on your rider weight and your main discipline. Guidelines:
- 38 L to 55 L: Prone Foil and Wing Foil for light to advanced riders (strong wind)
- 65 L to 85 L: Wing / Prone / Foil Assist versatility for 70-90 kg riders
- 75 L to 100 L: Foil Drive setup recommended by Armstrong (extra volume for balance, take-off and recovery)
- 115 L and 130 L: SUP Foil and Wing in very light wind, heavier riders or learners
If you're unsure, get in touch: our advisors will point you to the right board for your level, your weight and your program.
Yes. The board has a built-in remote signal window that gives a clear, interference-free connection to the Foil Drive unit. Armstrong recommends sizes 75 L to 100 L for an optimal Foil Drive setup (extra volume for balance and recovery).
No. The board has built-in strap inserts but the footstraps themselves aren't supplied. You can use Armstrong footstraps sold separately or the ones from your favorite brand.
Armstrong states that the Midlength Mk II is compatible with any foil system through the standard US foil tracks. Naturally, pairing it with an Armstrong foil (MA Mk II, HA, UHA, S1) or Foil Drive is optimized from the factory.
