You are on the right track wanting one with pedal drive but I will tell you my findings with them.
Most people are still going to some form of an electric drive for their Yaks. Either by trolling motor or the drive motors. So while the pedal driven ones do address some of the problems that anglers have with the paddle models, there still are things that are better suited for electric motors.
One of my biggest problems was actually getting mine to the water. You're either going to have to build a rack or buy a trailer, and that only gets you from the house to the lake parking lot. To get it in the water, you either gotta buy a dolly for it or drag it. And trust me, you're not gonna drag that sucker far before you get tired of it. Most of the pedal drive Yaks are right at 100 lbs empty, and then you've got to add in your tackle, life vest, anchor, maybe a drink or two to keep you hydrated out there, etc. The more you go, the more stuff you just gotta have, and that means loading and unloading. Then there is the room factor...in most of them, you are restricted to what you can reach while sitting in the cockpit. Storage compartments way in the front or back of the Yak are basically useless when in the Yak or at least they were to me. What I figured out was simply this: by the time I paid $2,000+ for the yak, then another $500+ for a electric motor, and then a trailer....I am at more money than what I could get an aluminum boat for with motor, trailer, and much more room inside it. I sold my Yak and haven't looked back. Lol
