Aqua Marina Slide-In Center Fin for Paddle Surfboards

Superior directional stability, quick tool-free installation, and maximum durability with the Aqua Marina Slide-In Center Fin

Get your paddleboard back on track or equip it with a high-quality replacement with the Aqua Marina Slide-In Center Fin. Designed as the official replacement and performance standard for Aqua Marina's wide range of iSUP boards and inflatable kayaks, this fin provides the directional stability (tracking) needed to maintain a smooth straight line without constant paddle corrections.

Made from high-tenacity fiberglass-reinforced Nylon, its structure combines lightness and resistance to minor impacts or accidental scrapes in shallow waters. Its main practical advantage is its Slide-In mounting system: simply insert the fin's base into the board's fin box and secure it with the included safety pin (clip). No tools, screws, or steel nuts that could get lost in the sand are required, making it easy to attach and detach the fin in seconds before storing the board in its backpack.

Key Features:

• Slide-In Fixing System: Ultra-fast assembly and disassembly using a sliding rail with a locking pin.

• High-Strength Synthetic Nylon: Great structural flexibility that withstands scrapes without easily fracturing.
