## Questions & Answers

**Q: Will this fit an irocker cruiser?**
A: This fits iRocker’s eariler model blackfins. 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

Bought this to fit to my SUP to take it on a river camping weekend. 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 great as had a few lakes to cross on the trip
