I was just thinking of versatility. 16 foot is real long for small river running. I've been using a 12 foot and that seems a might long for playing around. A kayak on a lake, other than the BWCA, sounds boring. Unless you add some sails and a ama's of course. Speaking of the BWCA, what does one of these weigh? Can't use the sail up there, but the pedal drive would probably go unoticed.

Man am I dumb, I really thinking about getting one of these.
