The Zen 4 Twin Fin is the most beloved and successful surfboard in the    Chemistry Surfboards lineup. Designed for speed, flow, and versatility, this high-performance twin fin delivers exceptional performance across a wide range of wave conditions — from punchy beach breaks to clean, powerful point waves.

Evolution of the Zen Series

Introduced as the latest evolution of the Zen line first launched in 2021, the Zen 4 features a refined outline with increased forward volume. This design upgrade provides excellent paddle power, early entry, and effortless wave-catching ability, making it ideal for everyday surf.

High-Performance Twin Fin Design

Built primarily as a twin fin, the Zen 4 features a 4-channel bottom that delivers surprising hold and drive, even in steep or hollow sections. A double wing pin tail enhances control and stability, allowing confident surfing in heavier, faster waves.

Versatility in All Conditions

The Zen 4 carves smoothly on rail without any wash-out at the end of turns. Its relaxed rocker profile promotes easy paddling and down-the-line speed, while still responding beautifully in powerful surf. Whether conditions are firing or sub-par, this board thrives.
