Frequently Asked Questions about Surf Fins

What is a fin?

A fin is a protruding and elongated piece made of fiberglass or plastic that is essential for controlling our board. Surfboards and boats require fins to achieve stability, control, and direction. At Mundo Surf, you will find them at a good price with all kinds of accessories to enjoy surfing.

What is a Tri-fin surf fin system used for?

The Tri-fin or "thruster" fin configuration is the most common and versatile on a surfboard.

It is the configuration that 90% of riders use, as it can provide the drive and speed of a twin fin but with the extra grip of the center fin, necessary for hollower and larger waves.

What is a Twin fin anchoring system used for in a surfboard?

This system of two fins is commonly used for retro-fish, mini-simons, or some other board models. It is also used by riders who like to have a lot of drive in their surfboard.

This system generates a lot of speed and drive. With a wide base on each fin, it allows for long and smooth old-school turns.

When to use a quad fin surf fin system?

A set of 4 surf fins, 2 in the front and 2 in the back, is the format that generates the most speed and grip for your surfboard. Since speed is essential in surfing, it is an option that more and more surfers are using.

Professionals usually use them in hollow and fast waves, while intermediate-level surfers can even use them in small waves for that extra speed they provide.
