Built for Durability

This upgraded SUP fin is constructed from high-strength PA66 material reinforced with 30% fiberglass for long-lasting performance in rough conditions. The matte-textured finish gives it a clean look while helping resist cracking and wear from sand, transport, and repeated use.

The thicker center profile and tapered edges help the fin move efficiently through the water while maintaining dependable stability for recreational paddlers and touring riders alike.

Easy Tool-Free Installation

No tools. No screws. No complicated setup.

This universal slide-in paddle board fin is designed for quick installation and removal so you can spend less time rigging gear and more time paddling.

The updated locking system helps keep the fin secure while paddling, even in choppy water conditions common around Panama City beaches, St. Andrews Bay, and coastal waterways.

Compatibility Information

This fin is compatible with many inflatable paddle boards using a universal slide-in fin box with approximately a 1.40-inch opening width.

Before ordering, we recommend measuring your existing fin base and fin box dimensions to ensure compatibility. Small variations may still fit depending on your board’s design.
