In this video, Ludovic provides a technical masterclass on pump foiling, a type of hydrofoiling where the rider stays above water by pumping their legs. He breaks down the physics of maintaining momentum and “pumping” indefinitely by focusing on weight distribution and timing.
Overview of Pumping Technique
The video is a deep dive into the four critical phases of the pumping cycle. Ludovic explains that the key to pumping longer and further isn’t raw power, but optimization and efficiency. By using slow-motion footage, he demonstrates that many riders waste energy by pushing at the wrong time, which causes the foil to “push water” instead of gliding through it. He emphasizes a smooth transition of weight rather than jerky movements to maintain the foil’s lift.
Key Technical Points
- The Four Phases: He breaks the movement into four distinct parts: the descending phase, the minimum elevation transition, the climbing phase, and the maximum elevation transition.
- Energy Management: The goal is to use as little energy as possible by only applying pressure at the specific moment the board is ready to react.
- Weight Distribution: Ludovic warns against pushing on the front foot to start a descent; instead, he advises a smooth weight transfer to let gravity and the foil’s natural pitch do the work.
- Pitch Control: He highlights the importance of “pitching up” without stalling, ensuring the foil remains in its most efficient “glide zone.”
- Recovery: A significant portion of the advice focuses on how to recover from a low-energy state by correcting the rhythm of the pumps rather than just pumping harder.
1. The “Dead Spot” Trap
Ludovic points out a common mistake: The “Dead Spot.” This happens at the very top and very bottom of the pump. Most beginners try to force the board through these transitions, but he explains that these are actually moments where you should be “weightless.” If you push during the dead spot, you’re essentially fighting the water, which drains your cardio in seconds.
2. The “Swing” vs. “Push”
He reframes the entire movement. Instead of thinking about pushing down, he suggests thinking about it like a playground swing. You don’t just jump on a swing; you find the natural frequency of the pendulum. By aligning your body’s rhythm with the foil’s natural frequency, you can maintain flight with about 30% less physical effort.
3. Equipment “Cheat Codes”
While he focuses on technique, he subtly highlights how a high-aspect-ratio wing (long and thin like a glider) reacts differently to these four phases than a “surf” wing. A reader would find it interesting that his technical advice changes slightly depending on how much “glide” your specific wing naturally has.
4. The Mental Game: “Visualizing the Curve”
Ludovic emphasizes a mental shift. Instead of looking at your feet, he suggests visualizing the S-curve the foil is making underwater. If you can “see” the curve in your head, your feet will naturally follow the path of least resistance.
A Quick Fun Fact
Pump foiling is one of the few sports where you are technically “creating your own wind.” Because there is no wave or sail, you are the engine. Ludovic’s method is essentially teaching you how to build a more efficient engine through physics rather than muscles.
