Overview

The Christenson Twin + 1 set is crafted to complement a range of twin fin designs, from high-performance models to more traditional fish shapes. This twin set excels at generating effortless down-the-line speed while providing a fluid and controlled feel during turns. The addition of the centre stabilizer fin enhances drive and predictability through the turning arc and when driving off the bottom.

Lending design elements from the keel category, the CC Twin features a full tip, straighter trailing edge and a high degree of sweep, meaning this twin set is geared towards smooth performance style surfing.

Mimicking the outline of the side fins, the new stabiliser template has the appearance of a shark's dorsal fin. Wide and stocky at the base, with a full rounded tip. The side and stabiliser fins work seamlessly together so you can push hard off the bottom and drive through turns without the fear of skipping out.

The Christenson Twin + 1 set is designed to work with specific models in the CC range, however it is also a versatile option for a wide range of surfboards, including fish, funboards, and dedicated twin fin setups. This design is perfect for surfers seeking a balance of speed, maneuverability when carving smooth lines or pushing limits in steeper wave sections.

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 pro-level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.
