bateau

A bateau or batteau is a shallow-draft, flat-bottomed boat which was used extensively across North America, especially in the colonial period and in the fur trade. It was traditionally pointed at both ends but came in a wide variety of sizes. The name derives from the French word, bateau, which is simply the word for boat and the plural, bateaux, follows the French, an unusual construction for an English plural. In the southern United States, the term is still used to refer to flat-bottomed boats, including those elsewhere called jon boats. Construction Bateaux were flat-bottomed and double-ended. They were built with heavy stems at bow and stern and a series of frames amidships, likely from natural oak crooks when available, and planked with sawn boards, likely pine although builders would have used whatever material was available. These boats would have varied from place to place, from builder to builder and also evolved over time, however in general, they were long and wide. The bottoms were planked and flat, without a keel, but possibly with a larger "keel-plank" in the center and sometimes reinforced with cross cleats. The sides were planked, tapering to sharp at either end. History The French explorers of North America used bateaux as well as the native canoes and cartols. The boats' shallow draft worked well in rivers while its flat bottom profile allowed heavy loading of cargoes and provided stability. The smallest batteau required only one crewman, while larger ones, reaching up to in length, required up to five. The largest batteaux could carry two to ten tons of cargo. Batteaux could mount a small sail although the flat bottom was not optimal for sailing. In military records, it is seen that the boats were propelled primarily by oars with one oar being used at the stern as a rudder.
