About this fin
The Christenson Tri-Quad fin set delivers a solid and dependable feel that can be pushed hard in critical conditions. Performance Material Size Overview The Christenson tri-quad has been spec'd to work across his performance and hybrid models. The point of difference with this set is that it's made from our Performance Glass material (PG - solid fibreglass layers) and features a custom foil that's engineered to deliver a medium/firm flex pattern. The set utilises the Accelerator thruster set paired with the Performer quad trailer fins. The Accelerator template is known as a versatile, all-round fin that delivers a balance of speed, flow & response with added control through turns courtesy of a fuller tip profile. Paired with the Performer quad trailer, the quad set will deliver a very solid and dependable feel that surfers can push hard without fear of losing control. The PG material was chosen by Christenson to work on a variety of his board models. While slightly heavier than our PC fins, the PG material provides a solid and connected feel when driving through turns and carves. 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 30 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 .
