You should seriously look at folding kayaks like Folbot (www.folbot.com),
Klepper and some others. Look at using the double with a single seat
setup. These folding boats can easily carry 300 pounds of stuff. They
paddle well and have been sailed around the cape, accross the Atlantic and
countless expeditions. The Folbot double is about 60 lbs, you can carry
wheels to help portages if you want, some fold very small. And you can
break them down if you want to portage that way. They sail well and some
have rowing options as well as the usual kayak paddling position. People
have slept in them in a pinch. For your stated needs you couldn't better
describe the strong points of folding kayaks. Check out "The Complete
Folding Kayaker" by Ralph Diaz.

What would be your choice for a non motorized minimalist long distance
touring boat suitable for extended trips on large rivers? I'm not so
much interested in manufactured name brand boats as I am in TYPES of
boats suitable for this use. The following criteria should be used.
1. Light enough for one person to portage over land and car top.80lbs
2. Able to carry enough food and water and gear for one week.
I'm guessing 300 lb capacity including person.
3. Able to allow the user to lie down and sleep in the boat if
necessary.
4. Able to be paddled by one person, rowed or sailed.
5. Able to withstand large wakes from commercial vessels and pleasure
motor boats.
