The 5.36" Big Boy Thruster Fins use an expanded performance outline to deliver reliable hold and smooth release across a wide range of shortboard conditions. Increased depth and base area enhance drive through turns while maintaining predictable response during directional changes.

Built from layered Pro Glass fibreglass, the fins offer consistent flex behaviour, structural durability, and dependable feedback under load. The irregular cream and black laminate pattern is integrated into the glass layup, creating natural visual variation without altering performance characteristics.

This Futures-compatible three-fin set is suited to surfers seeking stability, power transfer, and controlled turning from a larger thruster template rather than a standard medium outline.
