FCS II Modern Keel Twin Fins
Upright keel template designed for traditional fish shapes.
XL - One size fits all riders.
Features
- Upright keel template designed for traditional fish shapes.
- Lower sweep (rake) than most conventional, wider based keels which allows it to pivot in a really tight radius.
- High area and depth not only delivers a feeling of control when pushed harder on the open face, but helps to maintain tremendous speed through roundhouse cutbacks.
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 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.
