If I had to chose one boat to do it all, it would be a Pocket Canyon. Big enough to load a sufficient amount gear for more than week, small enough to paddle solo and tackle some good white-water. If you outfitted with a center air bag and some knee straps it is agile tandem canoe that can handle some really big water and that can be easily rolled. Light enough to keep your mouth clean while portaging on some hard trails. It is also surprisingly fast on flat water despite its rocker. A fun boat!
