Replacement Fins for Inflatable Paddle Board

【Perfect Compatibility & Pre-Purchase Clarity】: Side fins fit ~1.18 inch (30mm) base openings, while the 9-inch center fin fits standard ~1.38 inch (35mm) openings. We offer 3 side fin options to match most SUP bases—check our size chart for details. No guesswork, just a seamless fit for your longboard, surfboard, or inflatable paddleboard.

【Complete 3-Piece Set (No Fin Dock Included)】: Each order includes 1x9" central SUP fin + 2x5" side fins—everything you need for replacement or upgrade. Refer to our product size chart for exact fin dimensions; note: fin dock is not included to avoid unnecessary bulk.

【Upgraded Durable Material for All Adventures】: Crafted with 70% PA + 30% fiberglass (not just basic nylon!), our fins balance rigidity and flexibility. They resist fractures, handle calm lakes to choppy oceans, and stay tough through yoga sessions, weekend explorations, or pro-level wave cutting.

【Streamlined Design for Precise Control】: Aerodynamic fin shape follows hydrodynamics—boosts water-breaking efficiency and maneuverability. Whether you’re a beginner or pro, it enhances straight-line tracking, steady steering, and smooth turns, keeping you on course in any water condition.

【Quick-Release & Worry-Free After-Sale】: Pop fins on/off in seconds for easy storage/transport (no tools needed!). If the fins don’t fit your base (low probability), contact us for a hassle-free return or solution. Shop with confidence—we stand behind your on-water experience.
