Maximum Speed. Minimal Drag.
Tribal ASY Speed Carbon
A no-compromise, GPS-proven fin, built purely for Speed
Engineered for only one thing: top speed
The Asy Speed Carbon is THE go-to speed fin. Built purely for speed, the Asy Speed Carbon is a no-compromise, GPS proven fin designed to deliver the lowest drag and highest acceleration possible on broad reach and speed runs.
It doesn't compromise for comfort or versatility. This fin was created with one clear purpose: to go as fast as physics and conditions allow. With its optimised asymmetrical- ultra thin profile and full carbon construction, this is the fin used by record chasers and elite GPS sailors in optimal flat water locations.
If you’ve got the skills and the set-up, Asy Speed Carbon is your ticket to pushing the limits of what's possible on flat water in a specific speed direction and gives you the edge to set PBs, club records or even national benchmarks.
WHY ASYMMETRICAL MAKES A DIFFERENCE
In speed sailing, drag is the enemy. A symmetrical profile produces lift on both sides, but that means extra drag when you're only sailing on one tack.
The Asy Speed Carbon eliminates that extra drag. It uses a profile shaped to generate lift only on the active tack, giving more power, less drag and better acceleration. That’s how the fastest GPS runs in the world are made!

Frequently Asked Questions
Why do I need to choose Port (LHF) or Starboard (RHF) tack?
Asymmetrical fins only generate lift on one tack. Choose Port (left hand front) for typical left-to-right speed courses (e.g. La Franqui), or Starboard (right hand front) for right-to-left set-ups.
Can I use this fin for regular Freeride or Slalom?
No. The Asy Speed Carbon is designed only for straight line speed sailing on one tack. It’s not very suitable for gybing and sailing upwind can be hard.
Is it fragile?
No. It’s precision gear. As with all Carbon fins, avoid hitting sand or rocks. Use only in clean, deep, flat water conditions.
Will it improve my GPS results?
If you have the right spot, board and technique, absolutely. This is a race caliber speed fin for advanced riders.
