Armstrong Downwind Mk III Ocean SUP-Foil Boards 2025

The Armstrong Downwind Ocean

Harness offshore ocean energy.

Building on the legacy of the popular Downwind Performance board, the Downwind Ocean is slightly more compact and maneuverable while also being a faster paddling shape. The core evolution lies in its hull design which is now displacement rather than planing, leading to greater paddling speed and straighter tracking – without needing the length of the prior Performance board.

Speed

Access ultimate speed.

The new displacement hull results in greater paddling speed and straighter tracking, perfect for chasing down open ocean swell. It also now requires less effort to get up to speed, so when you’re digging deep for that last popup of the run, the board’s giving you every advantage possible.

Maneuverability

Surf the entire run.

Thanks to the faster shape, the Ocean is shorter than the prior Performance board per volume. If you’re looking to lay some snappy S turns all the way down your run, the Ocean is the board for you. With less length in the way, pumping responsiveness is also given a major boost.

Control

Put down the power.

The new shape features more rounded rails and softer chines that provide a consistent, comfortable stability so you can put down paddling power. The flatter deck now provides a wider standing area so you can get those feet whenever you want them for maximum control at Mach speeds.
