FUTURES Channel Islands AMK Twin Keel Fin

These fins are specifically designed for keel-inspired twin-fin surfboards. They excel on boards with a bit more volume and flatter rocker profiles, where you want to emphasize speed, glide, and drawn-out lines.

The solid glass construction provides a stiffer, more consistent flex pattern. This results in a very responsive, predictable feel that holds its shape well through high-speed carves, offering a more traditional, 'locked-in' sensation than lighter composite fins.

Yes, these are designed specifically for the Futures fin system. They will fit any surfboard equipped with standard Futures boxes.

They are incredibly versatile, but they really shine in small to shoulder-high conditions. The wide base generates significant drive and acceleration, helping you maintain speed through flatter sections or weaker waves where other fins might bog down.

Unlike upright twins that prioritize pivot and tight turns, the AMK Keel is built for projection and flow. The wider base and keel shape provide more surface area for stability, making them ideal for carving and maintaining momentum rather than quick, vertical snaps.
