I want to share my insights, particularly on narrow boards and downwind boards, which I’ve come to find offer a unique set of advantages and challenges in the sport of wing foiling.

I recently tried using a downwind board for wing foiling after seeing it become a popular trend locally. I was initially skeptical that the narrow, “torpedo-like” shape would provide enough stability, but I was blown away by how well it performed. This specialized wing foiling downwind board seems to have the volume distributed perfectly to provide exceptional glide in light winds while still feeling very stable and balanced.

I think that the future of wing foiling might lean towards longer and narrower boards. Their efficiency in generating forward momentum, crucial for wing foiling, sets them apart from traditional designs. This new shape is seen as potentially reshaping the sport, especially in light wind conditions.

The Advantages of Narrow Boards

The effectiveness of narrow downwind boards in picking up speed more easily than shorter, wider shapes is attributed not only to their narrowness but also to their specific nose and tail design. These boards have a “pointy”, wave-piercing nose and a similar tail, significantly impacting their hydrodynamics. The required effort to push the board through water depends on two key factors: the board’s projected area (as seen from the front) and its “aerodynamics” or friction coefficient.

Enhanced Speed and Glide

Narrow boards excel in their ability to generate speed and maintain glide. Their streamlined shape allows them to cut through water more efficiently than wider boards. This feature is particularly useful in wing foiling, where speed is crucial for getting on foil. A narrow hull requires fewer pumps and less effort to activate the lift, making the process of getting up on foil smoother and more efficient.

Improved Swing Weight and Responsiveness

A common misconception is that longer boards, especially narrow ones, have poor swing weight. However, my experience shows that narrow boards can initiate and move through rolls faster, providing a superior surfing experience. For instance, my 7’x20″ Starboard Ace Foil 2024, despite being longer, is of the best narrow boards I have tried and more enjoyable to ride than my shorter, wider boards due to its ability lift early and to quickly roll into turns.

Board Takeoff

Narrow boards, due to their design, lose hull speed less quickly when off foil, requiring fewer pumps to get up. This aspect becomes evident when comparing my experiences with different board sizes and shapes.

Light Wind Performance

The narrow board allows for the use of smaller wings and foils, facilitating easier lift-off with minimal pumping. This feature is particularly beneficial in light wind conditions, where maintaining momentum can be challenging. Additionally, the narrow board proves advantageous when the wind drops completely, as it can be swum back to shore twice as fast compared to wider boards.

The Challenges of Narrow Boards

Potential for Clipping the Nose on Waves

While narrow boards offer many benefits, they are not without their challenges. One issue is the potential for the board’s nose to catch on waves, especially in small period swell troughs. This problem can be mitigated by adapting to the board and choosing the right mast length.

Stability Concerns

Initially, there were concerns about the stability of narrow boards, especially when getting started. However, I found that the foil acts as a significant stabilizer, and the length of the board adds to overall stability. Once you’re up and winging, these boards stabilize quickly.

Suitability for Different Skill Levels

Narrow boards might not be the best choice for everyone, particularly for highly advanced riders who are accustomed to smaller boards. For beginners to advanced surfers, however, these boards offer numerous benefits both on and off foil.

Stance Adjustment

One downside noted is the need for stance adjustment due to the reduced width of the board. This change requires some adaptation but is manageable with practice and experience.

Handling in Strong Winds

Regarding concerns about long boards being difficult to handle in strong winds, I’ve found no issues on the water. The key is in understanding the board’s dynamics and adapting your style accordingly.

Comparing to Sinker Boards

While narrow boards might not replace sinker boards for highly advanced riders, they offer a broad range of benefits for most other skill levels. It’s important to evaluate these boards based on their unique attributes rather than directly comparing them to sinker boards.

My Journey with Narrow Boards

Progression and Gear Evolution

My journey through different board sizes and shapes, from a 5’10” x 29″ 123l board to a narrower 5’3″x22″ 83l board, has been eye-opening. The narrower boards have allowed me to push my limits, experiment with smaller foils, and enjoy a more dynamic wing foiling experience.

Safety and Relaunch Ease

The narrow boards also provide an added safety benefit. They paddle back to shore easily, which is reassuring when pushing limits. Plus, their relaunch is straightforward, inspiring confidence to attempt more advanced maneuvers.

The Perfect Kit and Further Testing

Finding the perfect wing foiling kit is an evolving process. My current focus is on finding the right balance of board size, wing, and foil to maximize performance in varying wind conditions. Additionally, I’m exploring how different board widths affect performance and how board weight influences ride quality.

In Conclusion

This comprehensive exploration of narrow boards in wing foiling reveals that they offer significant advantages in terms of speed, glide, and maneuverability. While they present certain challenges, these can be mitigated with experience and appropriate gear selection. For many wing foilers, from beginners to advanced riders, narrow boards represent a valuable option to enhance their experience on the water.

The introduction of narrow boards in wing foiling is opening up new possibilities, especially in light wind conditions. These boards, with their unique design and synergy with the right foil and wing setups, are not just a passing trend but a potential game-changer in the sport. As we continue to explore and embrace these innovations, the future of wing foiling looks both exciting and promising.

One thought on “Pros and Cons of Narrow Boards for Wing Foiling

    I have many wing boards including 93L, 74L, and 72L models in different dimensions. The narrower boards are easier to take off in light winds regardless of volume. With my 78kg weight, the 103L 7’2″ x 18″ DW board is just incredible. The first time I tried it in low wind and choppy conditions, the balance wasn’t too difficult.

    The wing assists with stability. It did not took much time to learn to start. You need little wind to get lift so 9-8kt is plenty. As you say in the article paddling is also very easy. What I found to be super nice is that in a choppy conditions with light winds, the DW cuts through better with less braking effect so you can take off faster. I am hooked on narrower boards I think I’ll never buy a board wider than 20″ again.
