- deal breaker
I SUP mostly shallow rivers in my area with plenty of rocks. The flexibility of this this fin allows me to hammer through them without getting spit off most of the time. The shape of the fin also makes my Rivershred track well going upstream. I've used it on the lake a few times and it has enough trail to make lake paddling enjoyable.
The fin fit perfect and works really well in the river. I appreciate that the screw is behind the fin so I don't worry about what it knock into. (it is a little harder to put in that way but not a deal breaker) I have an inflatable SUP and the rivers I love can run a bit shallow and rocky in places. This fin allows me to track and maneuver in the river without an issue and prevents me from bottoming out and going superman.
