Hey OP, I'm the OP of
>>129793Looks like you got it taken care of, my only recommedations would be to use old school external frame packs. You can put them frame side down in the bottom of the boat and it keeps them out of the water. They are also good for portages, put the middle thwart on the shoulder straps where it meets the frame. Put your sleeping bag in a dedicated dry bag that you can put in the normal spot, use old/cutdown canoe straps to attach.
I would also take a cartridge stove as they are a lot more user friendly than the whisper bomb, but six days is a while and you may use a lot of fuel. I would also throw in a grill, just a square grill. Dig a hole in a sand or gravel bar and you can use it to grill fish in foil.
Looks like fun, wish I was going.
