There are many inflatable canoes and you want to be looking at weight. My pack tops out at 50-55lbs and thats no inflatable, so I bet your looking at at least another 10lbs and then the paddle. Might want to go Kayak but if you have more gear a canoe is the way to go. Don't overlook the possibilities of using a canoe for shelter. Inflatable I don't know, I wouldn't do it but if travel is your game and portage is the name then you may need that. A regular canoe will provide a lot of shelter and warmth, and I bet an inflatable will do the same but dragging an inflatable through the woods might not be such a good idea. Then again if you have lungs like Franco Columbo you could always just deflate and inflate at will 🙂

i own already a cedar canoe but im looking for portge trough the woods
seen on tv show "ultimate survival alaska" some guys used back pack inflate canoe wich seduced me
http://channel.nationalgeographic.com/channel/ultimate-survival-alaska/
im looking for something similar

take a look at this awsome canoe http://www.prepperforums.net/forum/general-prepper-survival-talk/5543-canoe-ultimate-survival-boat-6.html thats bad asss lol

Inflatables are OK for short distances but they paddle like crap.
Canoes do great on very low input power. I thought about an outrigger and small sail on a canoe but never pursued it. The outrigger you could cobble together on site, all you would need to make is a mast mount, mast and sail.
I have a 12' aluminum canoe that is light enough to portage alone, barely enough for 2 people though.

As Perfesser said, inflatables paddle like crap, and that is not an understatement. They can be fun for running rapids in, but they have no discernible hull shape that would provide the required rigidity for any sort of efficient paddling. If you are looking for options that would make portaging through the woods easier, particularly if this means lighter weight, look towards kevlar boats. We've got tandem canoes at 18'4" that weigh in 44lbs. My brother paddles a solo canoe, 17'6" and comes in at 34.3lbs. They are pricey, but with some clever watching, he and I regularly find $3000 canoes, selling used for $750.

Another option, if you like the compactness of the inflatable boats, is to look into the folding canoes such as the ones made by Fol-bot and Pakcanoe. Assemble relatively easy, paddle much better than an inflatable, are pretty tough, and OKish on weight.

Those pack rafts are a beast, I agree across the board. They feel like you can use your legs like in a kayak, but they respond like a driverless semi rolling downhill sometimes. Unless they catch a teeny-tiny eddy.
They're harder to right, too, once they're over, and I keep feeling like the rivets are going to pop off one of these fine days.
Something that hasn't been addressed yet is "butt heavy" - which is in play with a lot of small boats, especially inflatables, but with the squat pack rafts like no others. The bag and legs only equal out so much, and I'm tall, but in some water ... one, you're straining looking up over a big backpacking rig like a grannie looking through a steering wheel and two, it really affects the steering. Maybe skinny and smaller people don't have as much problem with that, but I'm a pretty big girl.

That said, I do own two, so that I can float gear and a dog and the cat across a waterway. The bags that save your lungs are absolutely worth the money for a spare, even if you go with a foot pump as a primary.
I have a $500 USD 13' "kayak" (it's the open top design, two seater) that's better and replaced them in the truck because it's easier to tie something to as a stabilizer, and a $250 USD Advanced Elements inflatible kayak-kayak that I like the best. It has a big drawback, though. I'm nearly 200#, 5'10". That leaves me just 50# of weight to play with. That's okay, though, because you're not getting the dogs into it and it has laughable tie-downs. It's the better boat for take down and put-together, though, and a smallish pack (once it's removed). It handles better than any of my others and it paddles a whole lot better than any of the other inflatables I've tried.

thank you guys for all ur comment it help me
i like the idea of aluminium canoe and foldable canoe also seem very interesting but i would go for inflate canoe
near my BOL there 31 lake on the area and many river to cross
im not planning to go down rapid so i think even if inflate canoe paddle like crap i should be fine to can cross lake and small river
Regards

I doubt an inflatable would take well to being dragged over beaver dams and the odd log, something I do regularly.

Another option is the Sportsman's Pal. Its sort of like floating on a beer can but it is super light. I could carry it on one shoulder with my pack on the other for short distances. I took it a lot of places I probably shouldn't have. Nothing quite like traveling on a gentle river then going around a corner and being swept into class 3 rapids on the equivalent of a beer can to tighten you sphincter... Or dodging log booms. Ive been wanting a sit on top style since then because if I flip, I want to be able to climb back on. Unfortunately, that style is heavy and wont cut water well.
