  • Fin System: FCS II
  • Fin Set-Up: Thruster (set of 3 fins)
  • Construction: Performance Core, medium flex pattern
  • Fin Family: Reactor ("designed for speed and tight turns, with added tail release")
  • Suitable Conditions: Loves beach breaks, and good in any performance wave. Lively when the surf lacks oomph, but capable in hollow surf too
  • Ideal Board: Performance thruster or hybrid with moderate or low rocker

Defined by it's relatively upright and "pivoty" template, and featuring a centre fin slightly smaller than the side fins, the Reactor fin encourages fast surfing and tight turning arcs. Factor in the versatile Performance Core construction, and you've got a great all-round fin that will bring your rail into play and help you find speed in mushier surf.

Sam Lamiroy surfed this fin in a medium in Magicseaweed's recent fin test (see below for the full edit): "It made the board much more lively, especially in junky waves. It allowed me to put the board exactly where I wanted to. I remember Al Byrne once said to me, 'fins need to get you on the rail'. So it's less about driving and how they set you up. These fins allow you to turn in a tighter arc, get you on rail and allow you to really surf. [...] A very good fin."
