JS Industries Hydroglass Thruster Fin

The Hydroglass Signature Thruster is designed for versatility, performing best in open-face waves. Their refined template helps maintain glide and speed even in weaker surf, making them a reliable choice for daily sessions.

This construction provides a consistent, predictable flex pattern. It offers enough stiffness to generate significant drive and speed during turns, while still allowing for smooth, fluid rail-to-rail transitions.

These fins are compatible with both FCS II and Futures fin systems. You should select the specific version that matches the fin boxes already installed on your board.

They are designed to complement both. The high-sweep template provides the hold and control needed for high-performance shortboards, while the drive characteristics also work well to add stability and speed to fish-style boards.

Since these are available in multiple templates, you should select a size based on your body weight and the volume of your board. Generally, lighter surfers or those on lower-volume boards should opt for smaller templates, while heavier surfers or those on larger boards benefit from the increased surface area of larger templates.
