### ⭐⭐⭐⭐ 







  
  
    Does the job
  

*by N***S on Reviewed in the United States on August 17, 2016*

I use this on one of my SUP boards when the kids are using it or if I'm fishing shallow waters - does the job and no breaks after a fair amount of use.  Nice that it comes with one of the tool less fin screws.  The only downside is that it doesn't seat tightly in the skeg box of my boards (I think the tab for the fin screw is a little too thick, so the bottom of the fin doesn't bottom out in the box before the bottom of the tab seats down on the screw plate), but not an issue as I always have the fin slid all the way back and am not surfing with it.

    Seems to work!
  

*by B***U on Reviewed in the United States on June 20, 2021*

I've only tried it out once, a 3 mi. paddle with my touring isup. It seemed to work as well as the original fin. I got the flexible fin for floating rivers.

Added this to a Yolo racing board and turns are a lot faster
