Lightweight breakdown frame
Hey, new to the forum and loaded with questions! I have recently been floating rivers up above the Arctic Circle in AK. We have encountered some light class III using our a Ally canoes and done well, but we want to paddle some rivers with heavier class III and class IV water. (A folding canoe loaded with 3 weeks of camping and fishing gear is not the greatest whitewater boat as you might imagine) You cant stand up and fish either. I want a more stable boat that will handle bigger water and allows one passenger the ability to fish standing. This is a travel boat, not a play boat. I won't intentionally steer towards the biggest holes to play. I would also like the option to take a third person on the trip. All this is easily accomplished with a raft or cataraft but the problem arises from having to get the boat to AK on a commercial flight then load all this crap in a bush plane. Some of those guys are Nazis about weight. I have decided on a cataraft with pontoons from JPW. That way I can pack each pontoon in with other gear. Function, weight, and durability are primary, comfort is secondary. I need ideas for a minimalist breakdown frame that will:
1) be under 50 lbs.
2) Break down to meet minimum size requirements for checked baggage on a commercial flight.
3) assemble without tools or basic tools. (ounces matter)
4) be ultra reliable. ( the nearest road is hundreds of miles from these rivers and the pilot is planning on picking you up 65 miles south of where he dropped you off on a specific day at a specific hour)
Any ideas no matter how out of the box they seem are welcome. I have no experience with catarafts or frames but have experience with pipe and pipefitting/welding. I have been canoeing for over 30 years so I have some paddling experience.Thanks in advance, -Joe
