I tried to post a long reply, however, it got lost somewhere, so I’ll give the condensed version. Fly-boy hit most of the points. I find in saltwater there are two reasons to go kayak rather than pontoon, one is speed and the other wind resistance. Most of the time, I am chasing moving fish, so I have to be able to catch up with them, kayaks are much faster (except in the instance below). Also the wind is almost always blowing. I would hate to be in a pontoon in a stiff offshore breeze. Now that I’m used to it, I have no problem casting from a siting position in a kayak. In fact, I usually use a sidearm cast.
