Full-power thruster control in durable Pro Glass construction, tuned for larger surfers, powerful boards, and committed rail surfing.
Photo is indicative only as pattern layout is irregular.
The 5.36" Big Boy Thruster Fins are engineered to deliver reliable hold, controlled drive, and predictable release for surfers who require a larger, more supportive thruster template. Built in solid Pro Glass with an irregular red and black finish, this set provides consistent flex characteristics suited to performance shortboards, step-ups, and boards ridden with extra force through the rail.
The balanced outline and moderate rake promote forward projection without sacrificing turning response, making the template suitable for everyday surf as well as heavier conditions. Designed for Futures-style fin boxes, the three-fin configuration maintains stability under load while allowing clean transitions between turns.
