My buddy and I converted a couple of big wide light air sailboards into paddle boards with some added traction pads on the decks. It's really a cheap way to get into the sport and much better than spending $1000+ before you know if you'll like it or not. So now if the wind dies we put our sails away and paddle for a little while. If I'm spending the day on the lake when it's not windy i'd much rather Kayak though.

p.s carbon paddles are worth every penny.
