Rusty Thruster Fin

These fins feature a neutral template and shallow vector foil, making them a versatile, all-around choice. They perform reliably in a wide range of conditions, offering enough control for powerful surf while remaining responsive enough for smaller, weaker waves.

The G10 fiberglass uses a high cloth-to-resin ratio, which creates a stiffer, more durable fin compared to standard molded options. This construction provides a more precise, dynamic flex pattern and a crisp rebound, so you feel more energy return during your turns.

The Rusty Thruster Fin Set is available in both Futures and FCS fin systems. Be sure to check which system your surfboard uses before purchasing to ensure a proper fit.

Choosing the right size depends primarily on your weight and the volume of your surfboard. Generally, the Medium size is designed for surfers weighing between 145 and 195 lbs, while the Large size is better suited for surfers over 180 lbs or those riding larger, higher-volume boards.

The thinned tips are engineered to provide a snappier, more responsive feel during turns. By reducing the material at the tip, the fin can load up and release energy more efficiently, giving you that crisp rebound sensation.
