''Paopao'' (from the Samoan language, meaning a small fishing-canoe made from a single log), is the traditional single-outrigger canoe of Tuvalu, of which the largest could carry four to six adults. The variations of single-outrigger canoes that had been developed on Vaitupu and Nanumea were reef-type or paddled canoes; that is, they were designed for carrying over the reef and being paddled, rather than being sailed. Outrigger canoes from Nui were constructed with an indirect type of outrigger attachment and the hull is double-ended, with no distinct bow and stern. These canoes were designed to be sailed over the Nui lagoon. The booms of the outrigger are longer than those found in other designs of canoes from the other islands. This made the Nui canoe more stable when used with a sail than the other designs.
