How to Choose the Right Fin Setup

The quiet decision-maker under your board — here's what actually matters when choosing.

Fins are the quiet decision-maker under your board — they shape how it turns, how it holds a line, and how it feels the moment you put weight on your back foot. Here's what actually matters when choosing.

How many fins, and why

  • Thruster (3 fins): the most common setup and a genuine all-rounder — a good default if you're not sure yet
  • Twin (2 fins): a looser, faster feel, well suited to bigger or more experienced riders in our range
  • Quad (4 fins): extra drive and speed down the line, a favourite for punchier waves
  • Longboard Single or 2+1: built for the smoother, more cruisy feel longboards are all about

Fin box systems, briefly

Your board's fin boxes decide which fins physically fit:

  • Futures — single tab
  • FCS1 — two tab, screwed in
  • FCS2 (Click Tab) — no screws, clips straight in

If you're not sure which your board has, check the boxes themselves — the shape gives it away, and we cover this in the Fin Selector too.

The rest comes down to you, not just the board

Your weight, your local break, how powerful the waves usually are, and your skill level all shift which fin actually suits you best — a fin that's perfect for a heavier, experienced surfer at a punchy beach break can feel completely wrong for a lighter, newer surfer at a mellow point break.
