For any starter it’s difficult to pin down a go to suggestion because, at this point, you don’t know to what extent you want to pursue kayak fishing. $2000 is not an insignificant price tag. I got a simpler ($700) fishing kayak because I have the opportunity to fish multiple small bodies of water near the family property that have no public access. For this application the kayak is far superior to a canoe.
You’re likely looking at two different directions: a kayak that is more versatile with respect to standing for casting, pitching, etc. but is less efficient to paddle. Or… a kayak that is better suited for travel efficiency lending itself to bigger water and trolling but is not ideal to stand in. It’s worth thinking about the kind of fishing you want to do.
One thing to point out is: everything is work. It can be difficult to maintain position in the wind while in a boat. It’s certainly a factor in a kayak. It’s also easy to not think about distance when you have an outboard but in the kayak that distance is real. You’re likely looking at a nominal travel speed of 4 mph. I haven’t tried any of the pedal drives so I don’t know how well they aid in positioning for fishing. A normal rudder is operated with your feet so I don’t know that a pedal drive becomes hands free to turn the kayak. I’m assuming it’s easier than holding a paddle in your hands. Pedal drive or not the wind will be a challenge.
Personally, kayak fishing becomes more attractive if you’re already interested in silent sports. Kayaks work great in hard to access or out of the way places. There is a certain game that is played in terms of rigging the kayak for the fishing you like to do. If it’s simply a money question a 12′ boat with a 9.9 hp will give you a world of fishing to access.
