From FCS

This upright keel template is designed primarily for traditional fish shapes, but the application extends to contemporary keel shapes as well. It has a lower sweep (rake) than most conventional, wider based keels which allows it to pivot in a really tight radius.

The high area and depth not only deliver a feeling of control when pushed harder on the open face, but helps to maintain tremendous speed through roundhouse cutbacks.

Performance Glass

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.
