Ultimate Guide to Installing a Fin on Your SUP:

Slide the washer forward in the track to its designated spot.  This is where your fin will sit. Positioning the washer correctly is crucial for the fin's alignment, affecting the board's balance and your control while paddling. Take a moment to ensure it's placed exactly where you need it.

Lower the dowel into the track and slide it back towards the washer. The dowel acts as a locking mechanism, securing the fin's front portion and ensuring it stays upright and stable. This step is essential for maintaining the fin's position, especially when maneuvering through water.

Lower the front of the fin and line up the hole in the top with the hole in the washer. This alignment is crucial for the screw to fit through both holes seamlessly, ensuring the fin is securely attached to the board. A correctly aligned fin optimizes the board's performance, offering better tracking and stability.

Drop the screw in through the aligned holes and tighten into the washer.  Use a suitable tool for tightening the screw, ensuring it's snug but not overtightened. This balance is vital to keep the fin securely in place without damaging the board or the fin assembly.

Tighten the screw a turn and a half to two times after making contact with the bottom.  This ensures the fin is securely fastened, ready to withstand the forces of paddling. However, over-tightening can strip the threads or damage the fin box, so proceed with caution.
