I just got a kayak a little while ago and I really dig it, but there are times whe I stare whistfully at the float tubers. I think it reakky depends on the type of fishing you want to do - if you want to fish in lakes, the harbors, near the surfline, GET A FLOAT TUBE!! Nothing is worse than trying to paddle with one hand to avoid getting caught by a set wave while trying to fight a fish with the other. Kelp beds and water that is slightly offshore is the middle ground where both work well. If you are into going offshore looking for thresher sharks or other open ocean fish, get a kayak. Also get a kayak if you are into trolling. Some popular kayak models are the cobra explorer, perception swing, scrambler xt, and malibu 2. I have a swing, which is a fast boat,but not as stable as others. Basically its all about finding what is best for you. Just make sure it has lots of deck space, a comfy seat, and hattches if possible.
