=== Single-outrigger ("proa") === {{See also|Sakman|Walap|Wa (watercraft)}} [[File:National Museum of Ethnology, Osaka - Single outrigger canoe (model) - Woleai Atoll in Federated States of Micronesia - Collected in 1985.jpg|thumb|Model of a ''[[Wa (watercraft)|wa]]'', a single-outrigger vessel, from [[Woleai]] in the [[National Museum of Ethnology (Japan)]]]] A [[single-outrigger canoe]] is a canoe with a slender outrigger ("ama") attached by two or more struts ("akas"). This craft will normally be propelled by paddles. Single-outrigger canoes that use sails are usually inaccurately referred to by the name "[[proa]]". While single-outrigger canoes and proas both derive stability from the outrigger, the proa has the greater need of the outrigger to counter the heeling effect of the sail. The outrigger on a proa can either be on the lee or windward side, or in a tacking proa, interchangeable. However, more recently, proas tend to keep the outrigger either to leeward or to wind which means that instead of tacking, a "shunt" is required, whereby the bow becomes the stern, and the stern becomes the bow.
