How did the dug out canoe and outrigger framework originate?
No actual evidence of how the development of the outrigger concept exists. What we know seems based on the pretext that the most logical and therefore less intellectually challenging solutions manifested first, followed later by the more advanced concepts. The log formed the basis of the earliest water craft. With the development of tools, notably the adze (a timber shafted tool with axe like head fashioned from clam shell or sharpened rock) logs were subsequently dug-out. Some cultures, such as the American Northwest Indians, combined this with the use of fire to hollow the log out. Earliest evidence of this maritime development can be traced back to Papua New Guinea, however within Africa this practice was also widely practiced amongst ocean and river peoples. Hollowed out, the log thus became a canoe which provided protection from the elements and provision for storage. However it had limited stability in rough and choppy waters and a series of experiments were initiated to improve
