Rusty Surfboards Thruster Fin

The Rusty Thruster set is designed as a versatile, all-around performer. Thanks to the neutral template and shallow vector foil, they handle everything from small, mushy beach breaks to more powerful, lined-up surf with equal reliability.

G10 fiberglass is incredibly durable and stiff, which allows for a high cloth-to-resin ratio. This construction creates a very precise, dynamic flex pattern that feels predictable and responsive under your feet, especially when you are pushing hard through turns.

The thinned tips are engineered to provide a crisp, responsive rebound. This design helps you maintain speed and flow through your turns, ensuring the fins don't feel sluggish when you're transitioning from rail to rail.

These fins are available in both Futures and FCS configurations. Be sure to check which fin box system your board uses before selecting your set.

Size selection typically depends on your body weight and the volume of your surfboard. Generally, the Medium size is ideal for surfers weighing between 145 and 175 lbs, while the Large size is better suited for surfers over 175 lbs.
