Futures Billy Kemper Quad Fin

These fins are specifically engineered for heavy, high-energy surf. The upright template and stiff fiberglass construction are built to provide control and reliability when you are riding steep, critical sections where you need to hold your line.

The hybrid foil—80/20 on the front fins and 50/50 on the rear—is designed to balance drive and responsiveness. This setup allows for quick, precise rail-to-rail transitions while maintaining enough hold to keep you locked in during tight turns.

The Pivot template is designed for tight-radius turns and quick, snappy pivots. Because these fins are upright, they allow you to turn your board in a smaller arc, which is ideal if you are surfing aggressively in the pocket.

Full fiberglass provides maximum stiffness and durability, which is essential when surfing powerful waves. Unlike more flexible materials, this construction ensures the fins won't flex or lose their shape under the high pressure of heavy surf, giving you a consistent, predictable feel.

A Ride Number of 2.8 places these fins firmly in the 'Control' category. This means they are designed to feel stable and secure, prioritizing hold and predictability over speed generation, which is exactly what you want when the waves get serious.
