    Perfect Fit

    We lost a fin and tried this as a replacement. It fit perfectly on paddle board. Same durability and functionality. Thankful we didn’t have to buy a new board.

    Worked perfectly!

    I needed a replacement due to breaking one at the beach. Installed easily. The knot was not very good and was too excited to get in the water that I didn’t care. I ended up losing the fin from the time I loaded the board up to leave and arriving home. That’s my fault tho.
