Mast (sailing) single pieces of timber, which were known as pole masts. For square-sail carrying ship, the masts, given their standard names in bow to stern (front to back) order, are: Some names given to masts in ships carrying other types of rig (where the naming is less standardised) are: Most types of vessels with two masts are supposed to have a main-mast and a smaller mizzen-mast, although both brigs and two-masted schooners carry a fore-mast and a main-mast instead. On a two-masted vessel with the main-mast forward and a much smaller second mast, such as a ketch, or particularly a yawl,

Other similar craft include the snow and the pink. Both the
