DETAILED DESCRIPTION
The Entry Point to the Armstrong Carbon Range
Armstrong has positioned the MK II as the carbon entry point in their lineup. It’s the original mast, redesigned to offer carbon stiffness at a much more accessible price than the Performance or Performance-X models. For any rider wanting to upgrade from aluminum to carbon without jumping to a top-of-the-line model, the MK II checks all the boxes: dependable stiffness, progressive control, and the same build quality found throughout the A+ Armstrong range.
A 15.8 mm Profile for a Stable Feel in the Water
Where the Performance-X uses an ultra-thin 12 mm profile for pure speed, the MK II has a 15.8 mm thickness with a 116 mm chord. This more substantial profile gives it a very stable feel in the water, a huge plus for all-round riding, freeride wing foiling, progressive surf foiling, or SUP downwind. The mast tracks straight, isn't twitchy, and builds confidence in all conditions.
A+ Compatibility and Premium Hardware
The MK II is fully compatible with the A+ Armstrong system, mounting directly to all A+ Armstrong front wings, fuselages, and boards without an adapter. The hardware is identical to the rest of the range: it includes three M6 28.5 mm and five M7 26 mm 316L stainless steel screws with a Rainbow Titanium coating, five M7 T-nuts, one 8 mm titanium barrel nut, and a Torx T30 key. A padded bag is included with the mast for transport and storage.
Long-Term Reliability and Durability
Armstrong built the MK II for long-term durability, making sure it holds up to the demands of session after session. This is the everyday mast for riders who want a solid carbon investment without paying a premium for a highly specialized profile or carbon weave. The MK II is a true all-rounder, suited to every discipline in the A+ range: wing foil, kite foil, surf foil, SUP downwind, and wake foil. It's available in four lengths from 65.5 cm to 86.5 cm to suit all riding styles and water depths.

FAQ - ARMSTRONG MK II CARBON MAST
The Performance-X is a specialist mast: it has an ultra-thin 12 mm profile, UHM carbon construction, and an integrated 0.5° geometry, designed for advanced riders focused on pure speed and glide. The MK II is the carbon entry point: it has a more forgiving 15.8 mm profile, a wider 116 mm chord, and standard carbon construction, built for allround performance and daily use at a significantly more accessible price.
Yes, if your foil uses the Armstrong A+ system. The MK II uses the standard A+ connection, so it mounts directly to all current A+ front wings, fuselages, and boards without an adapter. Just check that your setup is A+ and not the older V1 system.
The 65.5 cm is ideal for flat water, learning, and small wave Surf foiling. The 72.5 cm is the standard allround choice for most conditions. The 79.5 cm gives you more clearance in chop. The 86.5 cm is reserved for bigger open water, downwind, or pumping sessions where more ride height is an asset. For the most responsive feel, choose the shortest mast that suits your discipline.
That's exactly how Armstrong positions it: the entry point to carbon. You get the stiffness and precision of carbon without the price of a high-end mast. Its 15.8 mm profile also has a similar feel to a thicker aluminum mast, which makes the transition feel natural. It's a mast built to last for many seasons.
Marine-grade 316L stainless steel and the Rainbow Titanium coating are the best materials for resisting corrosion in salt water. Armstrong uses them across the range to maximize the mast's lifespan, especially at the connection points which are under constant mechanical and chemical stress. Even so, always rinse your gear with fresh water after each session.
