Polynesian Oceangoing Sailing Canoe This is a Hawaiian replica of the type of large double-hulled canoe in which Polynesians sailed around the Pacific as they settled many different island groups. This canoe, called the Hokule’a, has taken many voyages using traditional Pacific techniques of celestial navigation. The two hulls provided greater stability, and canoes designed like this sailed thousands of miles over the open ocean. (© Monte Costa/PhotoResourceHawaii.com)
