Armstrong Downwind Mk III SUP-Foil Boards 2025

The Armstrong Downwind Mk III

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 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.

A goldilocks ratio of dimensions and volume makes for optimum glide, stability and maneuverability so you don’t need to be a pro to up your time on foil.

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.
