Firewire Machado Seaside Quad Fin

Yes, as long as your surfboard uses standard single tab fin boxes, which are compatible with the Futures fin system. These fins are designed to fit any board equipped with that specific box configuration.

The quad setup provides more speed and drive down the line, especially in smaller or weaker waves. While a thruster offers a more predictable, pivot-oriented feel, this quad set is designed to give you that extra acceleration without sacrificing the ability to make quick turns.

This combination creates a high strength-to-weight ratio. The bamboo provides a natural, lively flex pattern, while the carbon interlayers add stiffness and durability, ensuring the fins hold their shape under pressure without feeling overly rigid.

The added rake on the front fins helps with drawn-out, smooth carves, while the more upright trailer fins allow for tighter, immediate pivots. This balance creates a wider sweet spot, making the set versatile enough for both open-face carving and snappy pocket surfing.

The inside foil helps channel water flow more efficiently, which generates extra lift and speed. By transitioning to a flat foil, the design maintains a clean, predictable release, giving you a smooth transition between turns.
