• [Marine-Grade Durability & Performance] Crafted from high-impact reinforced polymer, these surfboard fins deliver exceptional saltwater corrosion resistance and UV protection. Engineered for rigorous wave conditions, the 9.2oz/261g design provides optimal weight-to-strength ratio, enhancing board stability without drag. Stiff yet flexible construction maintains integrity during hard carving turns, while anti-fade plastic ensures long-term color retention. Ideal for surfing, SUP touring.

Install in 10 seconds: Insert, slide, lock - no tools required. The adjustable depth collar allows 3-position height customization (2”-4” exposure) for shallow reef or deepwater performance. Removable design simplifies travel/storage - fits paddle board bags effortlessly. Note: Includes universal grub screw for vintage boxes.
• [Hydrodynamic Streamlined Design] Wind-tunnel tested profile reduces turbulence by 40% versus standard fins, delivering superior tracking and directional control in flatwater and waves. The aggressive rake angle (12° base) generates lift for faster paddle board acceleration, while deep-tapered edges prevent spin-out during sharp turns. Optimized flex pattern creates responsive wave engagement - perfect for downwinding, coastal cruising, or river SUP adventures.
• [Pro-Grade Construction & Versatility] CNC-milled base plate ensures zero wobble at 15+ mph speeds. Dual-density construction combines rigid core (for drive) with softer tip (for flex control). The 3-stage rocker profile enhances wave responsiveness while preventing ventilation. Non-slip grip pads secure footing during stand-up paddle transitions. Backed by 5-year saltwater warranty - trusted by coastal instructors and tournament paddlers.
