The double canoe constituted the backbone of Polynesian culture, since
it enabled the Polynesians to enter and conquer the Pacific. In Tonga, a
center of Polynesian navigation, two types were known: the tongiaki
and the kalia. Contrary to most contributions, the author argues that
the Tongans were not only the Western Pacific masters of navigation, but
also of canoe designing. Typical of Polynesian canoes was the sewing
technique which can be traced back to ancient India but was also
practiced in Pharanoic Egypt and southern Europe. The legend of the
magnetic mountain is to be viewed in this context. Oceanic navigation,
which declined during the 19th century, had developed its own
means of orientation at sea, including astronomy and meteorology.
