The ocean is not a backdrop. It is the whole point.

Understand the Water is POD's editorial series for people who spend serious time in the water. Not beginners looking for a starting point, not casual observers. People who want to go deeper into the mechanics of wave riding, bodysurfing technique, swim fin selection, open water swimming, ear health, and the physics of what actually happens when a human body meets a moving body of water.

Every article in this series is written from direct experience. No academic framing. No generic advice recycled from elsewhere. The same standard applies to every POD product function first; nothing is added that does not serve a clear purpose. This standard applies to every piece of content published here.

The series covers five disciplines: bodysurfing, bodyboarding, surfing, swimming, and open water. New articles are published regularly.
Published regularly, accurate, honest, and never needing updating, regardless of when someone reads it.

Read what is relevant to your water. Come back when the next one drops.

Understand The Water

Why Body Position Changes Speed in Bodysurfing

One of the biggest things bodysurfers feel in the water, often without fully putting it into words, is how much body position changes speed. Sometimes you feel light, clean and fast across the wave. Other times you feel heavy, flat...

How to Choose the Right Swim Fin and Why

Matching Fin Design to How You Move in the Water Choosing the right swim fin is not about chasing speed or power. It is about finding a fin that works with how you move in the water. Fins support movement,...

Swimming vs Bodysurfing vs Bodyboarding

How the Same Mechanics Apply Across Different Conditions How speed works in the water does not change. Body position, movement, drag, and control still apply. What changes is how you apply those principles. Different water environments and equipment shift the...

How Swim Fins Affect Position and Stability

How Fins Help Maintain Alignment and Control in the Water Movement creates speed, and fins help you apply it more efficiently. The next step is control. Control is what allows you to maintain position in the water. Without it, speed...

What Swim Fins Actually Do

How Swim Fins Support Movement in the Water Swim fins are often associated with speed, but they do not create it. Speed in the water still comes from how your body moves. Fins change how that movement is applied. They...

How Movement Creates Speed in the Water

Body Position and Alignment Speed in the water starts with how your body is positioned. Before any movement happens, your body either works with the water or against it. The difference is drag. A flat, aligned body reduces resistance. A...

Bodysurfing Speed - The Missing Link Most Riders Miss

For years, I wrote about handboard shape, bottom contour, concave, control, stability and how certain configurations improved speed on a wave. That was not wrong. It came from decades of testing in real surf, with and without a board, and...

Why Swim Goggles Leak (and How to Fix It)

When goggles leak, the session breaks down. You lose your rhythm, your sighting goes, and your attention shifts from the water to the equipment. The instinct is to tighten the strap. That rarely fixes it. Most leaks come down to...

The Invisible Cushion: Why Handboards Fail vs Physics-First

Beyond Buoyancy: Why "Floating" is the Enemy of Performance Have you ever felt your handboard "track" beautifully for a second, only to have the nose suddenly dive, or the tail slide out just as the section gets critical? Or perhaps...
