Deflow Rocket Thrusters - Large

These fins are generally better suited for intermediate to advanced surfers due to their aggressive pivot and responsive feel.

Large refers to the surface area of the fins, which provides more hold and drive for heavier surfers or those riding boards in larger surf.

These fins are compatible with specific box systems (Evo/FCS or Futures). You must select the version that matches your surfboard's installed fin boxes.

The Rocket Thrusters have a more upright template, meaning they turn tighter and faster than a standard raked fin, which is designed for holding long, drawn-out lines.

Yes, rinsing your fins and fin boxes with fresh water after every session prevents salt buildup and keeps the hardware in good condition.

Check if the grub screws are properly tightened. If the screw is stripped, replace it with a new one.

Check the fin box for sand or debris. Rinse thoroughly with fresh water and ensure the grub screw is backed out far enough to allow entry.

This may indicate impact damage. Inspect the base and foil for cracks. If the integrity is compromised, avoid using the fin to prevent potential box damage.
