SUP fin JP-Australia Race RTM US-Box 8.4

SUP Race RTM Fin is designed for high-performance stand-up paddleboarding – whether you're competing or covering long distances at speed. Its elongated, slim profile delivers outstanding tracking, meaning fewer paddle strokes per side and more efficient forward momentum. Constructed using RTM (Resin Transfer Molding), this fin offers an ideal stiffness-to-weight ratio, ensuring crisp responsiveness with minimal flex. Its hydrodynamic shape minimizes drag, helping you maintain top speed with less effort, especially over longer sessions. The US-Box mounting system provides broad compatibility with most race and touring boards and allows for quick installation and fine-tuning of fin placement to suit different conditions and paddling styles. Notes: The manufacturer does not include a screw for the US-Box system. It should be purchased separately
