Staysails are a type of sail used on sailing vessels. They are triangular sails set between the mast and the gaff of a fore-and-aft rigged vessel. The term 'STAYSAIL' comes from the fact that they are attached to the stay, which is a wire rope running from the masthead to the bow of the boat. The jibs are sails that are set forward of the mast and are used to help the boat turn into the wind. They are usually triangular in shape and are attached to the forestay, which is a wire rope running from the masthead to the bow of the boat.
