That's not nearly enough.
You need straight paddles of different lengths for paddling empty in three different waters: lakes, river currents, whitewater = 3 paddles
Then you need each two inches shorter to be of optimal length for a loaded boat = 6
Then you need bent shaft versions of each = 12
Then you need each paddle in a wood version and a carbon version = 24
Then you need each paddle with three different blade shapes: sugar island, animal tail, racing = 72
So, 72 paddles is the bare minimum. Then there are also different woods, various shapes of animal tail paddles and, of course, decorative and historical paddles. Et cetera, et cetera, et cetera. Ad, almost, infinitum.
