The FCS II Performer Keel Twin fin large/X Large fin set in the classy Performance Glass construction. This full-bodied template was designed to suit a range of traditional wide-tail fish models and is the highest area FCS II keel in the range.The Performer Keel has a neutral sweep angle, full tip and flowing curves that are synonymous with the performer family of fins. Predictable in nature with a turbo boost of drive and forward acceleration, this versatile keel is suited to heavier and more powerful surfers. The key features of the Performer Keel are stability, speed and control, with a hearty dose of drive and flow With maximum drive and flow on offer, the Performer Keel will have you soaring down the line, even in the softest of waves. When the section pops up you'll be able to jam a nice turn or carve with confidence and control.The Performance Glass (PG) fins are machine cut from layers of solid fiberglass. These fins are stiff, and are widely used by pro level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations. Don't be too scared by this description, some of the kooks here at boardshop have used them and they do actually work well!Give them a try! Several team riders have put these twins through their paces and loved them.PLEASE NOTE: These FCS II fins are NOT compatible with the original FCS and FCS Fusion fin plugs.

Overview
FCS II Fins are designed for speed, in and out of the water. Thanks to their patented tool-less system, you can swap fins with a simple click, no fin key or screws required. This system saves time and effort without sacrificing hold or performance.
Made for FCS II fin boxes - the ones with two slots and no need for screws. They’ll still work with optional grub screws if your board has them, but they’re not essential. If your board has FCS I (older screw-in) boxes, these won’t fit.
