Perfect
My ex unpacked my daughter's paddle board at Christmas and of course, the skeg went out with the trash. I had no idea if this model would fit, but thought it might be a universal size based on reviews and availability. I also couldn't tell what the little, black, side tab in the photos was for (my board does not have detachable fins); it's just the piece that slides through the channel perpendicular to keep the skeg from sliding out when the board is in use or transit. A better description in the product details would be helpful. The fin fits perfectly and was super easy to install. We put this on the turquoise-green Streak board kit (purchased from Amazon December 2020). (Note: I am not a fan of detachable stuff for kids! Nor am I fan of opening large boxes with multiple parts amongst the frenzy of Christmas morning, especially when said contents won't be used for several months.) ... show more

Perfect. Exactly as expected!
I needed a replacement after my fin/keel or whatever it's called decided to swim away in the local lake. I have a slight amount of warping around the part that holds the fin, so I was even more concerned about it fitting because of that. But I just made sure I chose the same length of fin as before and that it looked the same, and it worked out wonderfully. Slid in like a charm and looks even sturdier than the one by Aqua Plus SUP came with! ... show more

Works excellent for our paddleboard
The kids tend to get a little close to our beach and the fins break off. I always have these on hand and they’re a cinch to replace. Definitely recommend.
