FCS II PERFORMER QUAD SPLIT KEEL FIN SET
Overview
The Performer Quad Keel is based on the theory of taking a full-size keel template and turning it into a quad set by extracting area from the back of the fin and re-shaping it into a mini quad rear.
The side fins have been designed from scratch with the leading edge inspired by the popular Modern Keel, and a trailing edge similar to the Reactor template. The low-profile quad rear is compact yet matches aesthetically the side fins, almost like a little sibling.
The smooth curves directly translate to how this set feels in the water. The robust, rounded tip and high surface area across all 4 fins ensure this set has exceptional acceleration from take-off and plenty of down-the-line speed and drive. When turning it delivers a trustworthy feel with an underlying level of response that allows you to break the line and turn in a tight arc when the wave presents steeper and more critical opportunities.
Ideally suited to smaller, weaker waves, this set is adaptable to many higher-volume hybrid tri-quad models and quad-specific models such as the Machado Seaside Fish.
- Specialty split keel quad fin set.
- High area quad keel set adds bite and control to hybrid boards with wide tails, without sacrificing pivoting capabilities.

Performance Glass
Performance Glass (PG) fins are machine-cut from layers of solid fibreglass. 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.
