I will second the kayak or canoe option. I prefer the kayak, sits lower and more stable if you buy the right one. Now for a boat the old 14' Alumacraft semi V hulls are real light and great hulls team them up with a 18-25 hp boat motor and trolling motor and trailer and you would be well below your 1000 lb weight limit and a good rig in my opinion. A lot of people prefer the flat bottoms, but the semi V will ride a lot smoother and the person in the front will be a lot more comfortable when running in a chop.
