By far the most elaborate technically, the most seaworthy and carefully built, are the sea-going canoes of the third type (see Fig. II (3)). These are undoubtedly the greatest achievement of craftsmanship of these natives. Technically, they differ from the previously described kinds, in the amount of time spent over their construction and the care given to details, rather than in essentials. The well is formed by a planking built over a hollowed log and closed up at both ends by carved, transversal prow-boards, kept in position by others, longitudinal and of oval form. The whole planking remains in place by means of ribs, as in the second type of canoes, the kalipoulo, the fishing canoes, but all the parts are finished and fitted much more perfectly, lashed with a better creeper, and more thoroughly caulked. The carving, which in the fishing canoes is often quite indifferent, here is perfect. Ownership of these canoes is even more complex, and its construction is permeated with tribal customs, ceremonial, and magic, the last based on mythology. The magic is always performed in direct association with Kula expeditions.

After having thus spoken about, first, the general impression made by a canoe and its psychological import, and then about the fundamental features of its technology, we have to turn to the social implications of a masawa (sea-going canoe).
