The FCS surf fins play an essential role in the maneuverability, stability, and performance of your board. Among the most popular systems, FCS (Fin Control System) has established itself as a key reference since its launch in 1995!
Let's discover the latest FCS innovations, the different available fin models, as well as tips for choosing the ideal equipment based on your style and surfing conditions.
A continuous technological evolution: from FCS I to FCS II
At its launch, the FCS I system revolutionized surfing by allowing surfers to easily change fins thanks to a screwed plug system. In 2013, FCS introduced the FCS II system, which eliminated the need to use screws or hex keys to attach the fins.
The FCS II system is based on a pressure locking mechanism, allowing surfers to quickly change fins depending on wave conditions. This system has become a standard in the industry, with many modern boards directly compatible with these inserts!
The different materials of FCS fins
FCS offers a wide range of materials and technologies, each providing unique properties in terms of flex, weight, and performance. Here is an overview of the main models:
- Performance Glass (PG) These fins are designed to mimic the characteristics of traditional fiberglass fins. They are rigid at the base but offer progressive flex towards the tip, allowing for good control and increased precision in turns.
- Performance Core (PC) and AirCore AirCore technology incorporates a polyurethane foam core, making the fin lighter while maintaining optimal rigidity. This type of construction allows for better responsiveness and promotes more dynamic turns.
- Neo Glass Eco This innovation from FCS is part of an ecological approach. Composed of 50% bio-based resin and recycled fiberglass, it offers an excellent compromise between performance and environmental respect.

The new features of FCS in 2025
FCS continues to push the boundaries of innovation with new fin models and collaborations with the world's best surfers. Among the latest releases, we find:
- FCS II H4 Designed in Switzerland with extreme precision, this fin combines an asymmetrical design and ultra-light carbon construction to maximize speed and stability.
- FCS II Kolohe Andino: This signature model is ideal for surfers seeking optimal maneuverability and quick transitions between turns.
- FCS II Carver Neo Glass Eco An environmentally friendly option, perfect for long turns and powerful carves.
How to choose your FCS fins?
The choice of fins depends on several factors, including:
- Your surfing style The "Carver" derivatives are ideal for powerful turns, while the "Accelerator" favor quick transitions.
- Wave conditions Small fins with more flex are perfect for soft waves, while stiff fins will offer more control in hollow waves.
- Your board Some boards are better suited to wide or narrow fins depending on their rocker and tail.
FCS's ecological commitment
In addition to offering high-performance fins, FCS is committed to a more sustainable approach. With the range EcoBlend, FCS reduces its carbon footprint by using recycled materials and less polluting manufacturing processes.
Moreover, the company participates in reforestation and ocean cleanup initiatives, contributing to the preservation of our marine environment.
FCS remains the undisputed leader in the world of surf fins, combining innovation, performance, and environmental respect. Whether you are a casual surfer or a professional, there is an FCS fin perfectly suited to your practice!
Do not hesitate to test different configurations and to adapt your quiver according to the conditions and your style.
