What is surfing a twin fin like?

If you’ve never ridden a twin before, you’ve probably heard the standard: twins are fast and loose.

While that can certainly be true, there is a lot of variety in the world of twin fin setups.

How your twin fins will feel really depends on:

  • The template and flex of the fin.
  • The size and shape of your surfboard’s tail.
  • The toe-in angle of the fins.

A shorter, wider twin fin or traditional keel is going to feel fast and drivey.

A more raked, narrow twin fin will have a little more versatility and control in turns and vertical maneuvers.

As you increase the toe angle of the twin fins, you’ll sacrifice some of their natural speed for a little more response in your turns.

If you’ve got a hybrid surfboard with a 5-fin set up you can add a rear trailer fin to add some stability to the twin fins.

You’ve really got to experiment!


How to Surf Your Quad as a Twin Fin

If you’ve got a quad surfboard that you’d like to experiment as a twin set up, you’ll keep the front fins in and remove the rear quads.

Depending on the board’s design, this may or may not work well.

Do you have a need for speed? Twinnies might just be calling your name.

Like all things fins and surfboards, experimentation and new experiences is what makes the magic.

Twin fins are a versatile set up that can work in mushy waves to fast, hollow surf.

You’re sure to have some fun.
