FCS II Modern Keel Fins

Traditional keel fins are often swept back, which prioritizes drive and long, drawn-out lines. The upright template on these fins shifts the pivot point forward, allowing you to make tighter, more responsive turns without sacrificing the speed you expect from a twin-fin setup.

While designed with traditional fish shapes in mind, these fins are versatile enough for modern fish designs that feature a bit more rocker or performance-oriented rails. They are best suited for boards where you want to maintain that classic twin-fin feel but need a bit more maneuverability.

Performance Glass is stiff and consistent, offering a very reliable, predictable flex pattern. It provides a solid, 'locked-in' feel that handles speed well, making it a great choice for surfers who push hard through turns and want a fin that won't feel twitchy or unstable.

These are FCS II fins, meaning they are designed for the FCS II tool-less fin system. They will click directly into any FCS II box, but they are not compatible with older dual-tab systems that require screws.

These keels excel in clean, open faces where you can really lean into your turns and maintain momentum. While they provide plenty of speed in smaller waves, their design really shines when you have enough face to execute roundhouse cutbacks and drawn-out arcs.
