Z-Fins Silverline Fin (2026)

Z-Fins Silverline Fin

OVERVIEW

The Z-Fins S/LINE 2026 is a high-performance slalom and freerace windsurfing fin designed to deliver speed, control, and efficiency at a more accessible price. This second-generation S/LINE fin is based on the legendary Z-Fins SLM model, offering proven race performance without the full custom cost.

Built with 75% pre-preg carbon and 100% handcrafted, the Silverline fin achieves around 90% of the SLM performance at only 75% of the price. This makes it one of the best value slalom fins on the market for serious freerace and slalom riders.

On the water, the S/LINE slalom fin feels fast, efficient, and well balanced. It delivers excellent top speed and strong control, especially at high pace. Compared to the SLM, the wind range is slightly narrower, as the SLM offers more low-end power from its softer flex. Even so, the Silverline still unlocks the true potential of freerace and race boards, making it a perfect upgrade fin for riders who want real performance gains without entering the full custom price range.

The no tip cut design keeps the fin predictable and stable, while the single stiffness option ensures consistency across conditions. Produced in a focused 32–46 cm range, the Silverline covers the most popular slalom and freerace setups.

Available in Tuttle and Deep Tuttle, with Deep Tuttle compatible with Foil Box, the Silverline 2026 fits seamlessly into modern windsurfing boards.
