A Halkett boat is a type of lightweight inflatable boat designed by (1820–1885) during the 1840s. 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. Halkett's first design was a collapsible and inflatable boat made of rubber-impregnated cloth. When deflated, the hull of the boat could be worn as a cloak, the oar used as a walking stick, and the sail as an umbrella. This was followed by a two-man craft that was small enough to fit into a knapsack, and when deflated served as a waterproof blanket. Although widely praised by Canadian explorers, Halkett's designs had a limited market, and he was unable to persuade the Royal Navy that they would serve any useful purpose in general naval service. Efforts to market them as platforms for fishing and duck shooting failed, and they were commercially unsuccessful. Only two Halkett boats, that of Orcadian explorer John Rae, and one held in the Hudson's Bay Company Museum Collection at the Manitoba Museum are known to survive today. ==Peter Halkett== Peter Halkett was a Lieutenant in the Royal Navy in the 1840s. The son of John Halkett, a director of the Hudson's Bay Company who for many years had lived in Canada before returning to England, Peter Halkett had long held an interest in the exploration of the Canadian Arctic. He had a particular interest in John Franklin's disastrous Coppermine Expedition of 1819–1822. Franklin's three-year exploration of the northern coast of Canada in search of the Northwest Passage had ended in disaster amid accusations of murder and cannibalism, with 11 of the 20 members of the group killed and the survivors reduced to eating lichen, their own boots, and the remains of rotten carcasses abandoned by wolves. The party had become stranded on the wrong side of the Coppermine River after their boats had been destroyed in a storm; John Richardson had attempted to swim to safety and suffered severe hypothermia. A single member of the party had fashioned a small canoe from canvas and willow, and the survivors had been obliged to cross the river one at a time using the makeshift canoe. Halkett was an amateur inventor, and during his spare time whilst serving in the navy he worked on solving the problem of how to design a boat that would be small and light enough to transport easily on foot through wilderness, but robust enough to carry people in safety across wide bodies of water.〔 His solution was to design a boat in which all components would double as items of clothing, or accessories that Halkett assumed the user would be carrying in any event.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Halkett boat」の詳細全文を読む スポンサード リンク
