Around the canoe or bangca, an outrigger is a thinly, hanker, firm, hull used to stabilise an inherently unstable main hull. A outrigger is placed stiffly & parallel to a independent hull soh that the main hull is less in all likelihood to capsize. If only the single outrigger is utilized in a vessel, its weight reduces the tendency to capsize inside 1 counsel & its buoyancy reduces the tendency in the more counsel.

Within the rowing boat or galley, an outrigger (or merely rigger) occurs as triangular metal frame that holds a pin (into which the oar is slotted) away from a gunwale to optimize leverage.
