The Single F captures the essence of a thin single fin on a foil. This mid-length surf foil is designed to catch waves earlier, carve with more aggression, and extend every session. Its tight rocker, wide tail, and forward-positioned deck provide instant balance and a natural glide, from takeoff to turn.

Perfect for beginners, a valuable addition to any expert’s quiver—for both casual sessions and challenging waves.

The Single F comes without a pad to give you complete freedom of use, but can be paired with our dedicated pad—a recommended addition for reliable grip and more precise control on the water.

Experienced riders will appreciate it for its ability to catch more waves. More waves mean more time in the air and faster progress.

Experts will keep this in their quiver for smaller sessions, such as summer sessions. It’s also ideal for more challenging waves thanks to a faster takeoff and easier planing compared to shorter boards, which tend to pitch up during the takeoff.

The Single F is for those who want to surf more, carve deeper, and stay on the water longer.

The Single F is designed for those who want to surf more, carve deeper, and stay on the water longer.

The Single F was born from a legacy: surfing, the ocean, and those sessions you never want to end. AFS was founded in Brittany, at the heart of a surf territory that has shaped our vision of riding from day one.

Our reputation was built on wave riding and carving. The SILK range is the ultimate expression of that heritage. The Single F pushes surf foil further: more flow, more feeling, and above all more time on the water, through a mid-length shape designed to fly but crafted with the soul of a single fin.

A light concave underfoot for more control and engagement through turns, without ever sacrificing comfort.

Get on waves earlier and enjoy easy take-offs, even in imperfect conditions. The board then holds its speed effortlessly.
