Full Futures EA Arakawa

No, these are designed specifically for the Futures fin system. They will not fit into FCS or FCS II boxes.

This quad set is designed for boards with four fin boxes, typically performance shortboards or hybrids. It provides a more stable, drive-oriented feel compared to a thruster setup, making it ideal for down-the-line speed.

Solid fiberglass is stiffer and more durable than composite or honeycomb materials. This stiffness provides a very consistent, predictable flex pattern, which is great for maintaining control when you are pushing hard through turns in powerful waves.

Medium fins are generally recommended for surfers weighing between 145 and 195 pounds (65 to 88 kg). If you are outside this range, you may find the fins feel either too stiff or too loose depending on your specific board and wave conditions.

While they are engineered for critical, powerful conditions, the balanced template makes them surprisingly versatile. You will still get good maneuverability in smaller surf, though you might find a lighter, more flexible fin set provides more 'pop' in very weak waves.
