NRS SUP Board Fins

NRS SUP Board Fins let you customize your board for the type of paddling you're doing. Shallower ones for quick turns and rocky streams, longer ones for straight ahead tracking. Three interchangeable sizes to choose from. 2, 5 and 9 deep fins are interchangeable on NRS SUP boards and other boards that use the same holding plate: Item 86104.01. Fins are made of a rugged nylon reinforced plastic that can take the hard knocks of stand up paddling. Base of the fins is 1 38W x 7 38L. A tethered locking tab holds the fin securely in the plate.
