The S-Twin is a modern classic that blends timeless fish design with contemporary performance enhancements. Inspired by the original Sherman round nose fish, this board has evolved through rider feedback and real-world testing in surf zones ranging from Hawaii’s North Shore to Brazil and California. The result is a globally trusted, highly versatile twin fin that thrives in small surf but performs well across a range of conditions.
The S-Twin features a wide outline with a signature single wing swallow tail, allowing for a pulled-in tail block that adds control and pivot without sacrificing speed or flow. The board’s slight single concave fading into vee off the tailhelps generate lift and makes for easy rail engagement—even in weaker surf. The vee out the tail adds looseness and smooth transitions, keeping the board locked in and flowing through turns with confidence.
With its low rocker, the S-Twin is designed to fly in mushier, softer waves, yet its agility and control make it a legitimate year-round option. Ideal as a twin fin with a small trailer, the board encourages experimentation in both fin setup and size. Some surfers ride it longer for glide and paddle ease, while others downsize to create a compact, high-volume speed machine.
Pros:
Wide outline and pulled-in tail offer both drive and control
Vee bottom aids in smooth rail-to-rail transitions, even in gutless surf
Low rocker ensures excellent speed generation in weak waves
Twin + trailer fin setup offers versatility and creativity
Accommodates a wide range of sizing preferences
Cons:

Summary:
The S-Twin is a refined twin fin that blends fishy fun with performance-focused details. It’s fast, loose, and fluid, with enough bite from the pulled-in tail and vee bottom to make confident turns. Whether you're looking to cruise smaller waves or add variety to your quiver, the S-Twin delivers with style, adaptability, and all-around rideability. A must-have for surfers seeking classic lines with a modern twist.
