Progress without limits
Incredible pitch stability.
Unleash your inner foil ninja with the MA Mk II! This bad boy gives you the superpowers you need to level up your winging and surf foiling game. Coming from an HA foil? You're in for a treat—the MA Mk II is like having a forgiving best friend who catches you when you wobble, with stability so rock-solid you could build a house on it! The consistent lift will have you feeling like you've suddenly grown wings, making you brave enough to charge into those spicy powered conditions with a big goofy grin. Even the foiling royalty—like 2x GWA Wave World Champion Cash Berzolla—can't get enough of how this foil keeps things steady when sticking those "look-at-me-now" landings or going full beast mode in heart-racing conditions. Ready to make waves? Or rather, fly over them!
Draw your line
Foil section with a broad speed range.
The heart of the MA Mk II is its thoughtfully redesigned foil section shape, giving you an impressive range of speeds to work with. You'll appreciate how it now takes off at much lower speeds—just like the HA model—while still reaching the same exciting top speeds as the original MA. This versatility means you can confidently use the MA Mk II for whatever style you prefer, whether you're winging, prone foiling, or tow surfing. And don't worry about those occasional breaches—just like the original MA, this new version recovers immediately, allowing you to continue your ride smoothly without losing your momentum or confidence. It's designed to support your journey at every turn.
Dream carving machine 8 Aspect Ratio
Narrower span for a seamless roll feel.
The narrower span of the mid aspect outline increases carving speed for a given area compared to a high aspect foil, giving the MA Mk II a quick, seamless roll rate and super fluid carving feel. All sizes are 8.0 AR oriented at carving at higher speeds with increased pump and glide that’s perfect for surfing. Whether it’s winging or foil surfing, the MA Mk II is a dream to lay into a turn.

Armstrong Performance Mast Development
“As the sport develops, riders push themselves and the equipment to the limits. After listening to feedback, we wanted to develop a new, innovative, ultra high-performance mast that minimizes drag and ventilation while also being stiffer and even more responsive.” - Armie Armstrong
Collaborating with a team of America’s Cup foil engineers, we set out to develop a high performance mast to take us into the future. Our design goal called for a unique blend of strength, stiffness, drag and light weight. Combining CFD analysis with expert insight allowed us to tune each section of the mast from baseplate to fuselage connection for maximum efficiency.
“Working with the latest premium composites available, we torture tested over 100 prototypes to work out the optimal fiber orientation for strength and designed flex. In keeping with our philosophy of strength and light weight, we redesigned the mast top geometry to shave off every possible extra gram of dead weight.” - Armie Armstrong
Structural analysis shows that a combination of both high modulus (HM) and intermediate modulus (IM) carbon fibers best distributes loads throughout various sections of the mast. HM's stiffness minimizes flex in the mast's central strut area and IM's high tensile strength caters to the complex shapes of the top plate and fuselage connection.
The result is a top of the line mast consisting of top shelf materials, new mast section, refined baseplate, reduced drag fuselage connection and new construction method. Proprietary titanium M7 mast top hardware follows suit with a strong, light and drag reducing connection to the board.
These masts are designed with a mast rake angle. This fine tunes the board angle relative to the foil for a more comfortable and forgiving ride. It does not change the lifting force or balance of the foil itself, and it does not impact the foil’s “foot pressure” bias front or back. Board rocker also directly determines effective mast rake – boards from different brands have a variety of different rocker lines which influence rake angle – and more rocker in the rear half of board effectively increases mast rake. The 1 degree of rake we’ve placed specifically into the top of the Performance Mast shape provides three main benefits by adjusting the board relative to the foil underwater:
By bringing the foil closer to 0 degrees when the board is in the water, drag is reduced which makes takeoffs easier.
Touching down at speed or landing a jump is more forgiving and there’s less chance of crashing headfirst over the board.
By lifting the board nose slightly (1 degree = 17.46mm/m), mast rake makes it easier to ride fast without catching the nose at steep riding angles.
Simply put, the Performance Mast range takes the sublime Armstrong feeling further than ever.
The Armstrong Performance Mast range is a clean-sheet design created in collaboration with a team of America’s Cup foil engineers. These Performance series mast have achieved a unique combination of efficiency, stiffness, and control at speed that caters to wing, tow, and kite foilers. Top shelf materials have allowed this mast to take our sublime Armstrong feeling further than ever.
