Must Know Surf Fin Definitions

To know what fins will best suit your needs, you will need to be familiar with a few terms to better understand exactly what you are buying.

  • Template: The outline of the fin.
  • Area: The amount of area inside the template.
  • Base: The widest point of the fin (where the fin connects to the surfboard).
  • Depth: Distant from the tip of the fin to the base.
  • Rake: The angle at which the fin is tilted backward.
  • Flex: Flexibility of the fin for side-to-side movements.
  • Foil: The contours that run along the fin.
  • Toe: The angle the fins are pointed in towards the stringer.
  • Cant: The angle the fin leans towards the rail.

What to Look For When Buying Surfboard Fins

It is important to be honest with yourself when buying new fins for your surfboard.

You should strongly consider the size of the swell, the angle of the waves, the size of your board, the fin setup you would like to use, and whether you will be trying to generate speed or maintain it.

Keep in mind that the more rake the fin has, the more control you will have while sacrificing drive.

The less sweep your fins have the tighter your turns will be, which is best for punchy beach breaks and steep waves.

Greater sweep is ideal for longboards and rolling waves where slow long turns are favored.

Finally, the flex of the fin will affect your speed generation

The greater the flex, the more “whippy” your board will feel, but it will be easier to generate speed.

Less flex will maintain speed better while adding to your surfboard’s control.

Other aspects to consider include:

  • Fin Depth: Longer fins hold in the water better and therefore provide more control in turns. 

Shorter fins feel more “loose” and are best for spin-like maneuvers.

  • Base Length: The longer the base, the faster your board will be able to move, however, fins with shorter base lengths are capable of making sharper turns.
  • Cant: The greater the cant of your fins, the more playful your board will feel, and the more responsive it will be during turns.

Boards with little to no cant (90°) will have more drive, stability, and speed, but be slower to turn.

  • Toe: Fins that are “toed-in” will have better responsiveness but feel looser.

Fins with little or no toe angle will feel more stable and faster due to less friction but respond slower when on the rails.

  • Foil: A flat inside face of the outside fins creates a balance of control, speed, and looseness, while a curved or concave inside face maximizes lift and minimizes drag, which is ideal for speed generation.

What Are the Different Surfboard Fin Setups?

Although the list of surfboard fin setups goes far more in-depth than the short description below, the following table will help you gain an understanding of the most common fin setups.

Number of Fins Description
Single 1 One large single fin near the rear foot area, usually used on large surfboards.
Twin 2 A single fin on each rail on the surfboard.

 

This is a common setup for fish boards.

Thruster 3 Three fins of the same size. One on each rail and a single fin at the tail.

This is the most common fin setup.

2+1 3 The same as a thruster setup but the tail fin is larger than the two side fins.
Quad 4 Two fins on each rail. The rear fins are sometimes larger than the front fins.

Conclusion

When most people start surfing they don’t give much consideration to the fins on the surfboard that they are buying.

Everyone thinks about their surfboard size but fails to realize the significance your fins have on control, drive, stability, and speed.

It’s important to choose fins that best suit where you will be surfing, the board you will be using, your size, as well as your surf style.
