I saw one at the Tennessee Boat and Fishing show Friday. I've not paddled the Jackson's model, but I have paddled a Hobie Paddle Board, and I don't want anything to do with it. It's too much of a workout for me, slower than a kayak, turned slower, and can't pack as much crap on it. There is no seat, it's made to constantly stand (I have bad knees) you can place a cooler on it if you want to sit. The plastic thing/paddle holder is removeable. The Jackson Superfishal is HEAVY 69lbs, that's really close to the weight of a 12' kayak. I have seen one video of someone placing a 2 stroke motor on one, and that was interesting.
