Review on Tool-Free DORSAL Surf SUP Fin: Longboard, Surfboard, Paddleboard Center Fin For Improved Performance by Jon Robertson

Works well. I bought a plastic SUP from Home Depot and the included fin was very small, so the board didn't track well. It's a cheap plastic board and I wasn't expecting too much in the way of performance but having to switch sides after each paddle stoke was annoying. I was going to get rid of it but did some research and decided to try a larger fin. I'm getting around 3-4 paddle stokes a side now, so will hang onto the board as it can take a bit of a beating and not worried if my kids are rough with it. At least now I can go for a casual paddle and enjoy it. The first time I fitted the fin it was a bit tight in the slot but that was more to do with my board than the fin. I had to force it a bit the first time but after that it fits fine. I take it off every time I transport the board on my roof racks.
