Performance Overview:
These surfboard fins combine the speed and freedom of a twin fin with the added control of a stabilizer. The 5.5" twins generate strong drive and down-the-line speed, while the 3.5" centre stabilizer adds hold through turns and improves rail-to-rail transitions.

The balanced template avoids the extremes of ultra-pivot or ultra-rake designs, making this setup highly versatile across a wide range of conditions.

Construction Insight:
Pro Glass construction delivers consistent flex and long-term durability. Compared to lighter materials, it provides a more stable and predictable feel under load — ideal for surfers who want reliable performance in critical sections.
