The term "jib" is the generic term for any of an assortment of "headsails". Her normal sailing rig consists of a mainsail, foresail, two headsails, and no topsails. A boom may be found on small headsails. Either of the two headsails made be fitted with a boom or a wishbone boom. Triangular staysails set forward of the foremost mast are called jibs, headsails, or foresails. It had a long bow sprit with jibboom and up to three headsails. The simplest and most common furling systems are for jibs and other headsails. The addition of headsails can make a cutter-ketch. Many restrict the use of spinnakers, trapeze harnesses, and the use of twin headsails. Jibs and spinnakers are the two main types of headsails on a modern boat. Headsails may be used at the bow.
