A pirogue (or piragua or piraga) can be one of several kinds of small boats. One kind is associated particularly with the Cajuns of the Louisiana marsh. The early Cajun pirogues were cypress dugouts but today they are usually flat-bottomed boats. Pirogues are not usually intended for overnight travel but are light and small enough to be easily taken onto land. The design also allows the pirogue to move through the very shallow water of marshes and be easily turned over to drain any water that may get into the boat. A pirogue has "hard chines" which means that instead of a smooth curve from the gunwales to the keel, there is often a flat bottom which meets the plane of the side. The pirogue is usually propelled by paddles that have one blade (as opposed to a kayak paddle, which has two). It can also be punted with a push pole in shallow water. Small sails can also be employed. Outboard motors are increasingly being used in many regions. In West Africa they were used as traditional fishing boats.
