I read Undaunted Courage by Stephen E. Ambrose a few years ago, and lately I've been thinking about what it would be like to roughly retrace the Lewis & Clark expedition's route up the Missouri and down the Columbia. It's a not very well thought out, bucket-list sort of idea at this point, but while I'm procrastinating from doing my schoolwork I thought I'd put it out here:
What boat would you build for this trip?
I don't think I'd be interested in listening to a motor for that distance, and it would detract from the experience, so it would need to be a sail & oar design. There would be portages, first for dams on the Missouri and later for rapids and the rocky mountains. I'm not enough of a masochist to want to haul the boat over the mountains by hand, but for the rest of it it would need to be light enough to carry. For safety's sake I'd want at least one other person with me, so say a crew of 2-3. There's a lot of research on the route that I haven't done yet, all of which would probably inform the ideal design, but off the cuff, what would you do?
