So, we'd like to carry a boat for going down rivers and exploring curious things on water, while being self sufficient with food and camping equipment. Giving up on the boat and building bamboo rafts was one of the propositions:) We ended up buying a small 12kg inflatible kayak that packs in a 60L backpack,
I've discovered today that we are completely defeated by this awesome guy 200 years ago.
1840s, Peter Halkett Invented an unusual boat.
Halkett had long been interested in the difficulties of travelling in the Canadian Arctic, and the problems involved in designing boats light enough to be carried over arduous terrain, but robust enough to be used in extreme weather conditions. the hull of the boat could be worn as a cloak, the oar used as a walking stick, and the sail as an umbrella
Spurred on by the successful testing of the boat-cloak, Halkett designed a larger version that folded into a knapsack. When inflated, it could carry two men, operating a paddle on each side, and when deflated served as a waterproof blanket to allow the users to camp on wet ground Although the Admiralty saw no use to which Halkett's designs could be put in general naval service, this larger design was extremely well received by explorers
