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,

A modern ketch's sails may be any type of fore-and-aft sail, in any combination, and most are Bermuda rigged. The modern ketch is popular in northern Europe and among long distance cruisers. Both the ketch and the yawl rig have proved generally to be more suitable for motorsailers
