Deep Tuttle Box Fin S Max 39cm Select SML07430039

Description:

The Select S.MAX is a powerful, full-carbon slalom fin engineered for top-end speed and precise control in planing conditions. Constructed from a high‑modulus carbon layup, the blade offers an exceptional stiffness‑to‑weight ratio that transfers rider input into immediate forward drive. Its hydrodynamic profile blends the punchy power of the S1 pro with the sliding efficiency of the V.MAX v4, delivering both explosive acceleration and stable high‑speed glide. Designed for Deep Tuttle Box mounting, the fin installs securely on most slalom windsurf boards and is aimed at competitors and ambitious amateurs chasing speed. The refined outline and chord distribution reduce drag and improve tracking through turns and straight runs, while the carbon construction maintains shape and performance session after session. Lightweight and responsive, the S.MAX gives riders confidence at race pace and pairs naturally with stiff slalom boards and high‑aspect rigs.
