Made Simple: Armstrong’s Carbon Mast Lineup
Three Masts, Three Very Different Rides
Armstrong’s 2027 carbon masts split cleanly into three jobs: an accessible everyday carbon, a stiffer flagship built for power and feedback, and an ultra-thin glide specialist. Here’s how they compare, with the specs that actually change how each one feels on the water.
Carbon Mk II
Entry-point carbon. Stable, predictable, and accessible. The natural step up from alloy with reliable stiffness across every discipline.
- 0° geometry — stability & early take-off
- Refined section profile reduces drag
- 15.8mm section — stable, reliable platform
- Improved layup — stiffer without a harsh ride
Performance Mk II
The new flagship. Stiffest section in the range with sharper feedback and rock-solid stability for downwind, freestyle, and powered turns.
- Reworked section & chord shape — stiffness and efficiency
- Greater bending & torsional stiffness sharpens feedback at speed
- Refined mast top & fuselage joint — stiffer and smoother in the water
- Per-size angles & taper fine-tune control and efficiency
Performance-X
Thinnest section in the lineup. Lighter, looser through carves. Built for downwind, fast winging, and clean carving lines. Finesse over stiffness.
- 12mm section maximum glide; bye bye drag
- Ultra-high modulus carbon — thin profile, no compromise on weight, stiffness or feel
- Reduced chord — looser feel and fluid turns
- Refined mast top & fuselage joint — stiffer, smoother flow
- Per-size angles & taper fine-tune control

Which One Is Yours?
Carbon Mk II if you’re stepping off alloy and want a stable, do-everything mast at the friendliest price.
Performance Mk II if you want the stiffest, most connected ride in the lineup for powered turns and downwind runs.
Performance-X if glide and a looser, lighter feel through carves matter more to you than outright stiffness.
