I would recommend an AIRE Super Puma or just a Puma. The Super is a little bigger and longer. Both are small and stable. They are a three man set- up. I have used both and they are very similar. You would need the fly- fishing frame, which includes the frame, seats, oar locks..etc.
They are great boats and two guys can grab a side and toss it in the back of a pick- up truck.
I did a fishing trip on the Green River in Utah in a Super Puma that my boss owns. At this one rapid all the Dory type boats had to "rope" their boats through the rapid with no one on board. It looked difficult and time consuming. We blasted right through that rapid in the Puma and never had a problem.
They have a web site with good info.
