✅ Good Things About Solid Fiberglass Side Fins

1. Durability & Strength

  • Solid fiberglass is extremely strong and less likely to break or chip than plastic or composite fins.

  • Ideal for surfers who put their gear through heavy use or surf in shallow reef or rocky breaks.

2. Consistent Flex Pattern

  • Fiberglass fins have a more natural and consistent flex than injection-molded or cheaper composite fins.

  • This gives you better control and predictable performance, especially during high-speed maneuvers.

3. Better Drive & Hold

  • Offer less drag while still providing solid hold — especially good in smaller boards or looser setups.

  • Still maintains good bite in the wave face, particularly helpful for down-the-line speed and control in turns.

4. Responsive Performance

  • Solid fiberglass is stiffer than most plastics, which leads to faster reaction when you pump or carve.

  • This can make your board feel more lively and precise during turns.

5. Customizable for Fin Setup

  • A 3.43" side fin works great as side bites in a 2+1 longboard setup.

  • Their versatility makes them a popular choice across different board types and surf conditions.

6. Good for High-Performance Surfing

  • Favored by intermediate to advanced surfers who want more control at higher speeds or in punchier waves.
