Lesson 4 - Flex and Materials

Welcome to another lesson in our course! Today, we’re diving deep into the world of fins and understanding how flexibility and materials directly impact your board’s performance in the water.

Have you ever wondered why some fins provide better control in powerful waves, while others help generate speed in smaller conditions? It all comes down to thickness, outline, and, of course, the construction material of the fin.

In this video, you will learn:
✅ How flexibility influences turns and board responsiveness.
✅ The difference between stiff and flexible fins and when to use each.
✅ A comparison of the main materials used in fin construction, from plastic to high-tech carbon and kevlar.
✅ The impact of outline and thickness on fin flexibility.
✅ How to choose the right material for your surfing style.

If you want to understand how to get the most out of your equipment and improve your surfing performance, this video is for you!

See you in the lesson!
