Armstrong Foils Downwind MK III Foilboard

Downwind progression starts here.

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 thingsfun 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 manoeuvrability 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 fibres 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 manoeuvrability and a hyper connected feel on foil, delivering high performance to riders on all board sizes.

Features:

  • Displacement hull: Efficient paddling to get on foil easily.
  • Mini squash tail: Keeps dimensions compact with a clean release.
  • Flat deck: More foot placement options and increased volume per size.
  • Split foredeck: Sheds water with ease.
  • Vent: Maintains integrity of the board on hot, sunny days.
  • Raised deck wedges and arch bars: Dual central arch bars and rear corner blocks provide intuitive foot placement references.
  • New deck grip: Grippy, comfortable, and lightweight.
  • Forward Geometry Foil Track: Our proprietary Forward Geometry foil track increases
  • responsiveness by placing the foil more centrally and reducing swing weight in turns.
  • Carbon PVC Sandwich construction: Strong and super durable for endless shuttle laps.
  • Dual Carbon Stringer System: Deck to bottom i-beam dual stringers provide maximum
  • structural rigidity and durability.
  • Carbon foil tracks: Proprietary carbon fiber foil tracks are keyed directly into the fibers of the stringers for a fully integrated construction.
