A jib is a triangular Staysail set ahead of the foremost Mast of a sailing boat. Its Tack is fixed to the Bowsprit , to the bow, or to the deck between the bowsprit and the foremost mast. Jibs and Spinnaker s are the two main types of '''headsails''' on a modern yacht. On a yacht with two staysails the inner sail is called the staysail, and the outer (foremost) is called '''the jib'''. This combination of two staysails is called a '''cutter rig''' or a '''yankee pair''' and a yacht with one mast rigged with two staysails and a mainsail is called a cutter. A fully rigged Schooner has three jibs. The foremost one sets on the topmast Forestay and is called the jib topsail, a second on the main forestay is called '''the jib''', and the innermost is called '''the staysail'''. All three sails are both jibs and staysails in the generic sense. A square-rigged ship typically has four jibs, though vessels with more and fewer exist. Starting from the inside, these sails are called: # Fore ( Topmast ) staysail # Inner jib # Outer jib # Flying jib On yachts with only one jib, it is common for the Clew of the jib to be further aft than the mast, meaning the jib and mainsail overlap. An overlapping jib is called a ''genoa jib'' or simply a Genoa . On cruising yachts with more than one jib, it is common for the innermost one to be self-tacking, either by using a Boom along the foot of the sail, or by cleating the jib Sheet to a track, or both. On other cruising yachts, and nearly all racing sailboats, the jib needs to be worked when tacking. On these yachts, there are two sheets attached to the Clew of the jib. As the yacht comes head to wind during a tack, the active sheet is released, and the other sheet (the lazy sheet) on the other side of the boat is pulled in. This sheet becomes the new '''active sheet''' until the next tack. The "Hoyt Jib Boom" is a self-tacking jib used on some yachts where there is only a single jib to facilitate single handed sailing or sailing with unskilled crew. The "Hoyt Jib Boom" consists of a swivelling angled boom connected at the bow of the boat and which sweeps back under the jib and attaches to the Clew of the jib. The Jib sail tracks the main sail through a tack. In addition, a more efficient use of the jib sail is possible due to the better Jib shape as it is held by the Jib boom. "Wing a wing" downwind sailing is also made easier since the "Hoyt Jib Boom" acts as a pole off the wind. However, the "Hoyt Jib Boom" can affect ease of mooring - someone at the bow with a hook trying to tie up to a mooring buoy will be somewhat impeded. Also Passengers at the bow could trip or otherwise be bothered by this relatively solid boom since it is quite low to the deck, approximately at ankle height. Clearly the foot of the Jib is limited in size to the length of the Jib boom, therefore reducing the efficiency which might be obtained by using a jib which overlaps the main such as a Genoa Jib . The Harkin web site illustrates the three primary self tacking arrangements varying in complexity from the simplest traveller to the most complex Jib boom type. The traveller type self tacker with pulleys to the side of the deck has the advantage of keeping the foredeck clear but lacks the improved efficiency of the more complex Jib boom: {Link without Title} SEE ALSO |
