Float tube/pontoon/kickboat fisherman

[raincheck]

i am wanting to go from a float tube to a one man pontoon with a trolling motor. getting older and dont want sore legs from kicking all day--LOL

I have seen kayak's with motors.My self i plan on fishing moving water and won't need a motor too get in the way.Weigh is what i look at because i have too load boat at the water.Most kayaks will hold 300lbs or more.
