Looks great. Don’t fuss about it. Instead where are you looking. What are your arms( steering) doing ?

Change your line

Love it Steve !!

What master G said and try changing your line. You go straight to the bottom of the wave and decelerate

Understanding Waves and Energy Dynamics

1. The Nature of Ocean Waves

• Helix Structure of a Wave:

• An ocean wave is a 3-dimensional transverse helix. While the energy moves forward, water particles move in circular or elliptical orbits.

• Deep Water Waves: The orbits are more circular.

• Shallow Water Waves: As waves approach the shore, the orbits flatten into ellipses due to the interaction with the ocean floor.

• Takeaway for Surfers:

Waves don’t move in straight lines but in curves and spirals. Riding a wave efficiently means aligning with its helical motion.

2. Efficient Movement on a Wave

• Why Straight Lines Don’t Work:

Straight lines cut across the wave’s natural flow of energy, leading to resistance and instability. Waves are dynamic systems; to move efficiently, you must follow their curves.

• The Fastest Path – Arcs and Figure-8s:

• The most efficient way to travel on a wave is by carving S-shaped arcs or figure-8s, which sync with the wave’s energy flow.

• These movements align with the brachistochrone curve, the path that minimizes time while harnessing gravity and the wave’s lift.

3. Forces at Play in Surfing

• Centripetal and Centrifugal Forces:

• Centripetal Force: This “center-seeking” force is generated when you lean into a turn, keeping you grounded and stable as you carve along the wave.

• Centrifugal Force: This outward force occurs when you resist or fail to lean properly, often throwing surfers off balance.

• Practical Implications:

• Turning is essential to maintain control and balance. By leaning and engaging the rail early, you counter centrifugal force with centripetal force, keeping you locked into the wave.

4. Rail Engagement and the Coanda Effect

• The Role of the Rail:

• Your surfboard’s rail doesn’t slice through water like a knife. Instead, it uses the Coanda effect, where water clings to the rail’s curved surface, providing lift and hold.

• This interaction allows the board to grip the wave, giving you control and stability during turns.

• How to Engage the Rail:

• Apply pressure to your toe or heel edge to direct the water flow around the rail.

• Anticipate and start your turn before over-acceleration stiffens the board. Early engagement makes turning smoother and more effortless.

• Late Engagement:

• If you miss the timing, more water passes under the board, increasing resistance. In this case, you must go lower and force the rail into the water, which requires more effort and sacrifices grace.

5. Posture and Movement

• Low vs. Stacked Stance:

• Stacking for Stability: Aligning your joints (ankles, knees, hips, shoulders) like building blocks creates a stable posture. From this position, you can lean into turns without losing balance.

• Going Low Strategically: Lowering your stance applies more pressure to the rail but should be done to engage the rail, not just for balance.

• Over-crouching (without engaging the rail) wastes energy and limits your mobility.

• Key Principle: Use a combination of stacking and leaning to conserve energy and maintain control.

6. Anticipation vs. Reaction

• Anticipating Turns:

• Start your turns early, before the board stiffens due to over-acceleration. This keeps your movements smooth and minimizes the need for forceful corrections.

• Timing your bottom turn with gravity and the wave’s energy flow ensures an efficient and graceful ride.

• Reacting to Over-Acceleration:

• If you delay the turn, you may need to drop lower to force the rail into the water, making the turn look heavy rather than fluid.

Scientific Concepts Behind Waves

• Helical Motion:

Waves are driven by energy that moves in spirals. Aligning with this motion through arcs and turns helps harness energy efficiently.

• Chaos Theory and Quasi-Periodic Structures:

• Ocean waves appear chaotic but follow underlying patterns influenced by wind, swell, and bathymetry.

• These patterns are quasi-periodic (irregular yet structured), meaning surfers must adapt to shifting energy pockets on the wave.

• Prime Numbers and Wave Energy:

• Waves distribute energy in uneven (quasi-periodic) patterns, similar to prime number distributions. This explains why energy is concentrated in certain parts of the wave, like the pocket.

• Surfing involves finding these energy-rich zones and aligning your movement with them.

Key Takeaways for Coaches and Students

1. Waves Are Dynamic:

• Think of a wave as a moving helix with shifting energy zones. Align with its curves, rather than fighting them, to surf efficiently.

2. Timing Is Everything:

• Anticipate turns to avoid over-acceleration. Early engagement of the rail leads to smoother, more effortless surfing.

3. Engage the Rail with Precision:

• Use the Coanda effect to guide water around the rail, creating lift and hold. Apply pressure strategically, rather than forcing.

4. Posture Is Key:

• Stack your joints for stability and lean into turns. Only go low when necessary to engage the rail, not as a default position.

5. Adapt to the Wave’s Natural Energy:

• Waves are irregular and constantly shifting. Be present, flexible, and responsive to their dynamic flow.

This structured approach combines the science of waves with practical techniques, helping coaches and students understand how to harness energy and move with efficiency and flow. It’s not just about riding the wave—it’s about reading and aligning with its rhythm.
