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.

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)

Why Your Swim Goggles Keep Fogging Up - What Actually Stops It

When goggles fog, the session stops working. You lift your head more often, lose your line, and disconnect from the water. The fix is not a spray or a wipe. It starts with understanding why fogging happens in the first...
