4A Center Fin: The Benchmark of Longboard Performance in Surfboard Fins
The 4A Center Fin is one of the most trusted surfboard fins ever designed, delivering smooth control, powerful drive, and timeless longboard performance.
What is a 4A Center Fin?
The 4A center fin is a classic longboard template known for its balanced outline, moderate rake, and dependable hold. Originally popularised during the golden era of longboarding, it remains a go-to choice for surfers who want predictable, flowing performance.
If you’re looking for surfboard fins that combine tradition with versatility, the 4A is the benchmark.
Why the 4A Template Still Dominates
The 4A isn’t just a “retro” fin—it’s a refined all-rounder that works across a huge range of conditions and boards.
Core Performance Traits:
Smooth rail-to-rail transitions
Consistent hold through turns
Reliable noseriding stability
Controlled, predictable release
Unlike extreme templates (pivot or highly raked fins), the 4A sits right in the performance sweet spot.

Choosing the Right 4A Size
General guideline for surfboard fins:
9"–9.5" → Smaller riders / performance boards
10"–10.5" → All-round longboarding
11"+ → Maximum hold and noseriding
👉 Larger = more hold and stability
👉 Smaller = more looseness and manoeuvrability
