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

A surfer being pulled off balance in the surf as his surfboard leash reaches full extension under load, with the text "The Moment a Leash Snaps" above and "Fit Changes Everything" below overlaid on the image

Why Surfboard Leashes Fail Under Load and Snap

When a surfboard leash fails, it rarely happens gradually. It happens in a single moment under load, often when you need it most. One second, you are connected to your board; the next, you are watching it pulled away by...

How Different Wave Types Affect Bodysurfing Speed

Not all waves move the same. Understanding the ocean terrain is the first step toward mastering the line. A small, steep shore break can feel faster than a larger, slower-moving swell. The difference is not just size. It comes down...

How Surfboard Leash Stretch Affects Control and Safety

A surfboard leash does more than keep you connected to your board. Under load, it stretches, stores energy, and releases it back into the system. When this happens smoothly, it absorbs force and helps maintain control. When it does not,...

Hands vs Handboards - What Changes and What Doesn’t

There is a common belief in bodysurfing that the handboard is what creates speed. That once you introduce a board, everything changes. The reality is different. The handboard does not replace the hand. It extends what the hand already does....

How to Choose Swim Goggles for Your Face Shape

Achieving a reliable seal in the water is not a matter of luck or strap tension. It results from anatomical alignment. When swim goggles match your face shape, they provide a watertight seal with minimal pressure, allowing you to focus...

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...

How to Choose Swim Goggle Lenses for Light and Conditions

Why Lens Choice Matters in the Water Most people choose swim goggles based on colour. Clear, tinted, and mirrored lenses. What gets missed is why those lenses exist in the first place. Fit and seal matter. That part is solved....
