FCS I Surf Fins

FCS I is one of the most widely used surfboard fin systems in the world and has been trusted by surfers for more than two decades. At Boardwalk you'll find FCS I fins for a variety of surfboards, wave conditions and riding styles.

Whether you're looking for an all-round thruster setup, a fast twin fin or a replacement center fin, the right fins can transform the way your surfboard performs.

What is FCS I?

FCS I uses two screws to secure each fin in the fin box. The system is simple, reliable and still found on countless surfboards around the world.

While many modern surfboards now use FCS II or Futures, there are still plenty of boards that rely on the classic FCS I system.

Choosing the Right Fin Setup

The size, shape and flex of your fins have a major impact on how your board feels in the water.

• Smaller fins create a looser feel
• Larger fins provide more hold and control
• Stiffer fins offer drive and quick response
• Softer fins generate more flex and flow

Choosing the right fin setup allows you to fine-tune your surfboard for different conditions and surfing styles.
