The Downwind Mk III board is all about progression whether you’re just figuring out downwinding or
pushing the limits of surfing downwind in short period skatepark conditions. The displacement hull design
works wonders to increase paddling speed and help you get on foil, and the refined outline keeps things
fun once you’re flying.

Glide

Bump catching made easy.
The speedy new displacement hull makes getting onto bumps easier than ever. It’s quick and
efficient so you can get up to speed without needing perfect paddling technique or heaps of
strength.

Responsiveness

Lay down carves.
The Mk III’s outline is shorter and slightly narrower than the prior Downwind board for improved
maneuverability when on foil. Combined with the Forward Geometry foil tracks, that means you’ll
be carving harder and pumping more efficiently.

Comfort

No sacrifices for performance gains.
Despite the reduced dimensions, the Mk III remains comfortably stable thanks to its rounded rails
and flatter deck with increased standing room. The new rail shape makes the board’s roll stability
more consistent and comfortable so you don’t find yourself suddenly thrown off balance.

More Grip, More Control

Progression starts here.
The Downwind Mk III’s deck grip is tailored specifically to provide maximum control and comfort to enable
your downwinding progression. Similar in feel to the deck grip on our Surf foilboard, this design features
unique micro-cutouts through the main section of the grip that are grippy enough to feel securely locked in
for critical maneuvers but still flat enough for easy foot repositioning throughout your ride. Dual central
arch bars and rear corner blocks provide extra traction, and blue markings indicate the foil track location
underneath.

Proven Construction

Lighter, stronger.
A wraparound PVC layer gives the rails an extra layer of protection from paddle strikes and provides the
nose and tail with greater durability for getting knocked around during shuttle runs. Proprietary carbon
fiber foil tracks are keyed directly into the stringer fibers for a fully integrated construction.

Dual Carbon Stringer System

Maximum rigidity.
The ultra stiff double skin carbon PVC sandwich combined with Armstrong’s reputed i-beam top to bottom
dual stringers provides maximum structural rigidity and durability. Proprietary carbon fiber foil tracks are
keyed directly into the stringer fibers for a fully integrated construction.

Forward Geometry Foil Track

Easier paddle up and improved responsiveness.
Emphasizing modularity within board design, Armstrong introduced a major innovation to foilboards in
2021 with the Forward Geometry concept. Designed to work with any brand of foil, the FG design
increases responsiveness by placing the foil more centrally and reducing swing weight in turns. The new
Downwind Mk III board carries on that design legacy with FG foil tracks that are strategically placed well
forward for maximum maneuverability and a hyper connected feel on foil, delivering high performance to
riders on all board sizes.
