Then you're right, Badger.
In fact the problem is in the terminology: river sup should be sup in rivers, which do not necessarily occur to have white waters. And if not, the boards (and the fin set) should be almost the same as for open waters (I use a flexible long central fin in such rivers).
What we usually call "river sup" should more precisely be defined as "white water (river) sup".

Badger, you are in the wrong section with your advice: here you are in the "Whitewater and River Sup" :-)
You simply cannot go on whitewater with fins even half long the one you mention.

Hi everybody from Italy, this is my first message, I guess, thus a short presentation: I'm Andrea, 50 y.o., 30 years amateur paddling on all kind of canoes and waters and since 2011 only sup. I've been practising river sup since last year.
To reply to your question: The trend now for river sup is 2+2 lateral fins 2" height. Central fin is not used. Moreover in turbulent waters a taller fin proves contraindicated because of instability trasmitted to the board. On the contrary, for calm rivers central taller fin (say 5") helps a lot the directivity.
