Overview
- Upright keel template designed for traditional fish shapes.
- Lower sweep (rake) than most conventional, wider-based keels which allows it to pivot in a tight radius.
- High area and depth not only deliver a feeling of control when pushed harder on the open face but help to maintain tremendous speed through roundhouse cutbacks.
- Black and clear in Performance Glass.
Board Types
- Designed to fit the FCS II Fin System.
- Recommended for all board types including fish, funboard and twin fin boards.

Performance Glass
Performance Glass (PG) fins are machine-cut from layers of solid fibreglass. These fins are stiff and are widely used by-level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.
