JS Industries Hydroglass Thruster Fin

These fins are designed for open-face waves that reward drawn-out carves and powerful, committed maneuvers. The consistent flex pattern helps you maintain speed through turns, making them ideal if you prefer smooth, rail-to-rail transitions over quick, snappy pivots.

Yes, they are specifically optimized to generate drive and glide, which helps maintain momentum even when the waves lack power. While they excel in open-face conditions, their ability to create speed makes them a reliable choice for less-than-ideal days.

The Hydroglass Signature fins are built using 34 layers of glass bonded with polyester resin. This high-density construction creates a very consistent flex pattern, which translates to a more predictable and stable feel under your feet compared to lighter, more flexible fin materials.

These fins use the FCSII single-tab system, which is the industry standard for most modern performance surfboards. They are specifically recommended for use with the JS Industries Charger and Daily series, but will fit any board equipped with standard FCSII boxes.

The thruster setup provides a balanced feel, offering a mix of control, drive, and maneuverability. It is the most versatile configuration for a wide range of conditions, giving you a reliable pivot point in the center of the tail while maintaining hold on the rail.
