I am considering the purchase of a watercraft for fly fishing of mainly lakes, ponds or slow streams. I have a float tube, but with that much of my body in the water in early spring, I can't last too long in the cold water. I am looking at pontoon boats, prams or any other such floating vessel that fits the need of a fly fisherman. So I would like to know what fits your needs and what model and key features you find important.

Thanks in advance.
