Mine is a 2019. I believe the US fin box had been replaced on the blackfin paddleboards newer than 2019. So I don’t think/know if it would fit any new iRockers. **Q: Is this fin still installed with the screw in the front and the pin that slides along the shaft towards the back (stern) of board!** A: There are photos of the fin installed on the amazon product page. The pin is in the front, the screw is in the back. **Q: Does this come with the ‘no tool’ fin screw? One place says it does and another place says it does not.** A: Yes, if you select the option with fin screw (usually the more expensive option) No, if you select the option without screw (see photos, and descriptions) **Q: I have a Riviera RP 12'6 . Was wondering if the it will fit ? Thanks** A: Yes, this should fit your SUP ## Customer Reviews ### ⭐⭐⭐⭐⭐ Did the job and tuck a few knocks as the river was shallow over some rapids but kept me pointing in a straight line which was gr *by A***R on Reviewed in the United Kingdom on 30 January 2017* Bought this to fit to my SUP to take it on a river camping weekend.
