Fore-sails include jibs, genoas and staysails. For racing purposes, extra sail can be carried&colon; additional staysails and spinnakers. In addition, there are 3 staysails on the main mast. Most staysails are triangular; however, some are four-cornered, notably some fisherman's staysails. Variations in the sail plan were tried, particularly with additional jibs, gaff rigging and staysails. As a result, the vessel lost topsails and staysails. Square-rigged masts may also have triangular staysails that are deployed fore-and-aft between masts. Actually, all three sails are both jibs and staysails in the generic sense. Triangular staysails set forward of the foremost mast are called jibs, headsails, or foresails.
