Maximum drive and down-the-line speed from a controller-style split-keel quad template, built in durable solid black Pro Glass for powerful hold and smooth release.
The 4.7" / 4.25" Controller Split Keel Quad Fin set is designed for surfers seeking strong projection, extended rail hold, and fast acceleration in modern quad surfboards. The split-keel inspired front fins generate substantial drive and stability, while the slightly reduced rear fins maintain manoeuvrability and controlled release through turns.
Constructed from solid black Pro Glass fibreglass, these fins provide consistent flex behaviour, structural strength, and long-term durability suited to regular surfing. The larger surface area and drawn-out template support confident performance in powerful waves while still maintaining responsiveness in everyday conditions.
This quad configuration is produced for compatibility with FCS-style dual-tab fin box systems and is supplied as a complete four-fin set ready for installation.
