Scale: Unknown. A model of an oru or outrigger canoe from Sri Lanka made entirely in wood which has been varnished a mid brown colour. The hull consists of a long narrow dugout with two broad washstrakes sewn onto each gunwale to give more freeboard. Both washstrakes have gunwale beading lashed to their upper sides. The method of sewing produces a series criss-cross pattern with vertical bars over a lath on the outboard side of the hull and vertical bars on the inboard. There is an off centre float that has been carved from a single piece of wood which is connected to the starboard side of the hull by a pair of booms. The two booms are each made from a single piece of wood, and between them an open platform frame has been rigged and attached to the gunwales. Two long rectangular planks of wood are attached to the gunwales fore and aft which serve as fore and aft decks.

The oru is sophisticatedly designed to combine speed, manoeuvrability and stability. The shallow draught dugout log hull is raised with side washstrakes fixed on shaped inserted frames and sewn to the hull with coir rope. Similar sewing patterns are found on the sewn boats of the Indian Ocean, such as the mtepe, the beden of Somalia, the sambuq of Oman, the oruwa of Sri Lanka and the Indian masula surf boat.
The hull ends are sharply raked for riding the surf. When sailed the outrigger float is kept to windward, counteracting the wind pressure on the sail. The two booms connecting the float to the hull also support a platform for fishing gear and crew. In lieu of a keel leeboards can be used which can be raised when beaching or when in shallows. A steering oar is used at either end of this truely double ended craft. Orus are found on the West and South coast of Sri Lanka. Those from the South set a rectangular sail on a T-shaped mast and yard; those from the West set a rectangular sail on a V- shaped mast and sprit. The crew on larger orus can number up to eight.
