The Kon-Tiki expedition was a 1947 journey by raft across the Pacific Ocean from South America to the Polynesian islands, led by Norwegian explorer and writer Thor Heyerdahl. The raft was named Kon-Tiki after the Inca god Viracocha, for whom "Kon-Tiki" was said to be an old name.
A raft is any flat structure for support or transportation over water. [1] It is usually of basic design, characterized by the absence of a hull . Rafts are usually kept afloat by using any combination of buoyant materials such as wood , sealed barrels , or inflated air chambers (such as pontoons ), and are typically not propelled by an engine.
A raft is a structure with a flat top that floats. It is the most basic boat design, characterised by the absence of a hull. The classic raft is constructed by lashing several logs, placed side by side, to two or more additional logs placed transverse to the others. In many Asian countries, the rafts are similarly constructed using bamboo.
A Carley float. The Carley float (sometimes Carley raft) was a form of invertible liferaft designed by American inventor Horace Carley (1838–1918). [1] Supplied mainly to warships, it saw widespread use in a number of navies during peacetime and both World Wars until superseded by more modern rigid or inflatable designs.
There are many types and combinations of these materials with lower-end entry-level paddles being composed of cheap aluminum and plastic. Higher-end models are constructed of high-end composites and mostly utilized by professional rafting guides, raft racers, and expedition paddlers. [5] The basic paddle design for rafting consists of 3 parts:
Rafting to Vancouver, British Columbia Canada (August 2006). Raftsmen in Northern Finland in the 1930s Timber rafting on the Willamette River (May 1973).. Timber rafting is a method of transporting felled tree trunks by tying them together to make rafts, which are then drifted or pulled downriver, or across a lake or other body of water.
Heyerdahl was born in Larvik, [8] Norway, the son of master brewer Thor Heyerdahl (1869–1957) and his wife, Alison Lyng (1873–1965). As a young child, Heyerdahl showed a strong interest in zoology, inspired by his mother, who had a strong interest in Charles Darwin's theory of evolution.
The final design was capable of hooping 1,600-1,700 barrels per day, far more than a barrel cooper could hoop on their own. [ 8 ] By 1912, Beasley's barrel-hooping patent had been generating $20,000 in annual royalties (equivalent to $651,655 in 2024) – much of it from oil and sugar refineries with whom the invention had become popular.
