Chipironier, also known as a batel, batteleku trainera or "gazolin", are one of the smallest traditional coastal fishing vessels on the Basque coast. Originally made of wood, with a length of 4.50 to 8 m (14.8 to 26.2 ft), its lines are characteristic of the long tradition of Basque shipbuilding in the Basque country. First operated by sail and rowing, this type of propulsion has greatly influenced the architecture of coastal navigation boats. It produced boats with long, narrow, light shapes and shallow draft, shapes which offered little resistance to advancement.[1] These boats adopted the engine at the beginning of the 20th century from 1920.[2] The crew is made up of one to five men.
