Nose

The front tip of the board that enters the water first.

Tail

Rails

The edges of the board that slice through the water.

Rocker

The curve of the board from nose to tail when viewed from the side.

Concave

Channels carved into the bottom that direct water flow.

Stringer

The wooden strip running down the center of traditional boards.

Foil / Thickness Flow

How thickness is distributed from nose to tail.

Key Takeaways

Volume matters most - It determines paddle power and wave-catching ability more than any other factor.

Rails are underrated - They affect forgiveness, speed, and control more than most surfers realize.

Rocker matches waves - More rocker for hollow waves, less for mushy waves. It's that simple.

Tail width = power handling - Narrow for power, wide for weak waves. Match your tail to your local conditions.
