Hi. I just purchased my first "proper" SUP. I need a small river friendly fin for it which I assumed would be easy to find and quite cheap - seems I was wrong :-(
Any suggestions on how to find a river fin at a reasonable price?
Thanks - Doug
Is it a US box (like longboard)?
Old windsurfing waveboards used to use 19 - 25cm fins like that and nobody wants them anymore. Get a half stuffed one and sand it a bit to refresh - $30 ish
Windsurfing Perth will have plenty, if you don't mind plastic which would be fine for the river: www.seabreeze.com.au/Classifieds/Windsurfing-Accessories/~-id_9/2016-Plastic-Fin-9-ABase.aspx?_page=8&search=gvyj2BKrnvk2v6j2XgqwWg%3D%3D
I have this fin from Hala gear that is a 4.5" flexible fin. Other companies sell the same fin in the 4.5" and shallower 3" as well. It fits most fin boxes. If you do a search for river fin for stand up paddling, you will probably get a hit from a company closer to you that sells a river fin.
Another option is to get a standard dolphin fin or touring option that has some flex/plastic construction and sand it down for shallow water use. Most inflatables come with these flexible dophin fins standard, and shops typically carry aftermarket dolphin fins.
