Inflatable Boards Back Fin US Box 21cm Unifiber UF097070010

Inflatable Boards Back Fin US Box 21cm Unifiber UF097070010

Description:

The Unifiber Inflatable Boards Back Fin (US Box, 21 cm) is a high-performance rear stabilizer designed to improve tracking and directional control on inflatable stand-up paddle boards (iSUPs) and touring boards. Constructed from glass-fiber reinforced nylon, the fin delivers a stiff, impact-resistant blade that resists flex while remaining light for easy handling. Its hydrodynamic foiled profile reduces drag and increases straight-line efficiency so you cover more distance with less effort. The 21 cm depth is optimized to add stability in flat water and chop without compromising maneuverability in small surf. Precision molding and a reinforced base ensure durable fitment into a standard US Box, while the black, low-glare finish blends with most board designs. Ideal for recreational paddlers through experienced tourers seeking improved tracking and stability on long paddles.

Recommended Use:

This back fin is ideal for recreational and advanced paddlers who want improved tracking and stability for touring, fitness paddling, and general all-around use on inflatable SUPs. It performs best in flatwater, open-water touring and choppy conditions where added directional control prevents yaw and reduces corrective strokes. Pair with your board’s center/side fins and a reliable leash; most users will find it complementary to traction pads and backpack carry systems for longer excursions.
