Dave is correct in saying that they both have their advantages and disadvantages. Being able to move and fish and the same time is one of the main things I've loved about float tubing for the past 15 years. In freshwater I like the "stealthness" of being so small. Kayaks on the other hand cover way more ground (or water). When I'm out and see birds going crazy working the bait too far away for me to kick in my float tube is when I wish I had a kayak. Having both is the way to go!!!<P>You can't catch tomorrow what you kill today - please practice catch and release.
