The pivot fin model is often overlooked, but this test shows it is a serious competitor to the standard Greenough 4A raked fin. The difference between the two boils down to a trade-off between nose stability and turning looseness.
Key Takeaways & Tips
Pivot Fin Design
The pivot fin is significantly wider at the base than the Greenough 4A, taking up nearly the whole fin box base. It sits more upright and is slightly stiffer than the raked fin, resulting in a very flowy, controlled feel.
Noseriding on Pivot Fin
Noseriding on the pivot fin feels like driving a Cadillac—it is extremely smooth, stable, and locked in. The wider profile provides confidence to launch into the critical part of the wave, anchoring the board securely in the pocket.
Greenough 4A Performance
The Greenough 4A excels due to its looseness and speed, which makes the setup for the nose ride nearly effortless and allows for the quicker turns needed on an unpredictable beach break.
Fin as a Quiver Staple
Both fins deserve a place in your quiver. The pivot fin is ideal for predictable waves where nose riding is the goal, while the Greenough 4A is better suited for fast, weird, and unpredictable waves where looseness and speed are priorities.
Common Mistakes to Avoid
Flubbing the Cutback
When riding the pivot fin, you need to be slightly more deliberate with your foot placement. Failing to get your back foot close enough to the tail and placing it in the middle of the board will cause you to flub the cutback.
Avoiding Wider Fins
Shying away from beefier, wider fins. While the Greenough 4A provides adequate stability, wider pivot fins offer a new level of nose stability that is worth experimenting with.
Riding Pivot in Fast Waves
Choosing the pivot fin on an unpredictable, very fast day. On such days, the speed and looseness of the Greenough 4A are necessary to quickly adjust and maintain momentum.
