Captain Fin Co. Jeff McCallum Quad

These fins are specifically engineered for boards with wider tails, such as fish, grovelers, or hybrid shapes. The quad setup helps generate speed and maintain drive on boards that might otherwise feel sluggish in flatter sections.

The Jeff McCallum Quad Especial is designed exclusively for the Futures fin system. Please ensure your surfboard is equipped with Futures boxes before purchasing, as they are not compatible with FCS or other fin systems.

The flat foil on both the front and rear fins provides a consistent, predictable feel through turns. It allows for a clean water flow, which helps you maintain speed and responsiveness without the added drag sometimes found in more complex foil geometries.

Yes, the fiberglass construction offers a more rigid, reliable flex pattern compared to standard composite fins. This stiffness translates to better energy return and stability, especially when you are pushing hard through high-speed maneuvers.

These are size Large fins, which generally provide the best hold and drive for surfers weighing between 165 and 195 pounds (75-90 kg). If you are significantly lighter or heavier, you may want to consider a different size to ensure the right amount of surface area for your weight.
