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.

How Your Arms Control Direction and Speed in Bodysurfing

Most people think of bodysurfing speed in terms of the wave, the fins, or the handboard. But your arms play a much bigger role than many riders realise. They do more than sit in the water. They help guide direction,...

Mirror vs Clear Swim Goggles - When Each Actually Works

Most people choose swim goggles based on how they look. The lens colour, the frame, the mirror finish. What matters more is whether the lens matches the light you are swimming in. The wrong lens does not fail immediately. It...

How Trim Controls Speed on a Wave

Most bodysurfers have felt it. You take off clean, the wave has energy, the line looks good, and for a moment, everything feels light and fast. Then the speed drops away. The board feels flatter, the body feels heavier, and...

Why Body Position Changes Speed in Bodysurfing
