Madagascar outrigger pirogues have their origin in two main regions of the globe: the Indonesian’s Arc-Borneo (two floats canoes) and Sri Lanka (single float canoes). Cultural intermingling and good seamanship, gradually evolve from these two influences the typical Sakalava pirogue. She is composed of a narrow center hull (usually between 4 and 9 m) made with a hollowed trunk topped by several pieces of timber and assembled planks. The float is built in a very light wood. It is linked to the hull by two highly flexible and solid wooden poles cleverly fixed with ropes, ensuring to the whole a high resistance combined to flexibility.
