DW / SUP Foils

Downwind (DW) foiling is akin to SUP surfing; the difference is that it  involves riding a hydrofoil board while harnessing the energy of wind and waves. This discipline allows riders to glide over the water by utilizing the downwind side of groundswells, or shorter range wind fetch.  

The key to selecting a downwind setup is finding the right balance between stability, lift, and speed. While a low-aspect, slow foil may be wonderful for developing the skills to link bumps, it can be frustrating to paddle up and may not be ideal for those who want to progress more quickly.

Moreover, large surface areas offer more lift and stability at lower speeds, making them ideal for beginners or those in less powerful swells. A mid to high-aspect front wing of 1200-1600 cm² is a good starting point, depending on your body weight. A great example is the Unifoil Progression 200 at 1290cm².

Mast length is also important; a longer mast will offer more stability and clearance, but  it can be harder to paddle up due to added drag. Conversely, a shorter mast may breach too easily, depending on swell size. A mast around 75-80cm seems to be the best of both worlds. As for the rear wing, we suggest you go as big as you can find in a high-aspect shape.

Once you are capable of foiling efficiently downwind, pumping and gliding can be made more efficient  with a higher-aspect foil with a shorter chord and longer wingspan.

Tips for Downwind Foiling

1. A larger front wing can help with early lift and stability but may require more skill to maneuver effectively. For example, a front wing size around 1260 cm² is recommended for optimal performance if you are 175-180 pounds.

2. A mast length of around 75–80 cm strikes a balance between stability and ease of paddling up onto the foil.

3. A carbon paddle is preferred for efficiency; aim for at least 50% carbon content for optimal performance.

4. Wearing a helmet and buoyancy vest is advisable to enhance safety during rides, especially in challenging conditions.

Downwind foiling represents a thrilling way to explore wind driven swell and ground swell by combining elements of surfing, paddling, and hydrofoiling. By selecting appropriate gear—specifically designed foils and boards—and following best practices, riders can enjoy this unique discipline while maximizing their time on the water.
