One watercraft that I never see mentioned is the two man fishing boat, available from Bass Pro, Cabela's, etc. They're designed to be used w/ an electric trolling motor and cost in the $4-500 range plus $100 for the motor. They are extremely stable and I would have no hesitation in taking any of my equipment out in one. I canoed a lot as a young man, but now, in my 70's don't have the strength or endurance to use a paddle for very long. I initially bought mine for fishing, but after frequently seeing good opportunities for waterfowl and wading bird photography, I started carrying a camera and long lens on all my trips. I wouldn't take one on big waters, but most of my fishing is on small watershed lakes, etc. I rigged one up specifically for photography, w/ lowered seats, camouflage, etc. but found I could approach just as close in the conventional mode, so I've stuck with that.
