FCS II Modern Keel PG Surfboard Twin Fins Natural/Alpine
The FCS II Modern Keel PG Surfboard Twin Fins in Natural/Alpine are engineered for traditional fish shapes and twin-fin setups, providing precision, speed, and control. Featuring an upright keel template with a lower sweep (rake) than conventional fins, these keels pivot easily in tight turns while maintaining stability through roundhouse cutbacks. Their high area and depth give surfers confidence when pushing hard on the open face, making them ideal for agile, performance-focused riding.
Constructed from Performance Glass, these fins are stiff and durable, maintaining consistent flex even under extreme forces. Compatible with the FCS II Fin System, they suit a wide range of boards including fish, funboards, and twin-fin designs.
