Another common feature are pitched roofs with ornamented gables. The most notable of which are the saddlebacked roofs, a design common for longhouses used for village meetings or ceremonies. The overall effect of which is reminiscent of boats, underlining the strong maritime connections of Austronesian cultures. The boat motif is common throughout, particularly in eastern Indonesia. In some ethnic groups, the houses are built on platforms that resemble catamarans. Among the Nage people, a woven representation of a boat is added to the ridge of the roof; among the Manggarai people, the roofs of houses are shaped like an upside-down boat; while among the people of Tanimbar and eastern Flores, the ridge itself is carved into a representation of a boat. Furthermore, elements of Austronesian structures (as well as society in general) are often referred to in terminologies used for boats and sailing. These include calling elements of structures as "masts", "sails", or "rudders" or calling the village leaders as "captains" or "steersmen". In the case of the Philippines, the villages themselves are referred to as "barangay", from an alternate form of "balangay", a type of sailboat used for trading and colonization.
