Traveler. A sail-positioning system composed of a track on which slides a car attached to blocks to permit positioning sheet leads under load. The parts of the running rigging: mainsheet block, traveler, traveler car/track, halyards (jib, spinnaker, main), mainsheet, cunningham, boom vang, gooseneck, jib cunningham or jib downhaul, topping lift, downhaul, whisker pole, spinnaker pole. Figure 6–1 Main Sheet Traveler System

Figure 6–2 Boom Vang Boom Vang. A tackle, usually running between the boom and the base of the mast, which removes twist from the sail and tightens the leech by downward pull on the boom. Tackle. An arrangement of line and blocks used to provide increased mechanical advantage.

Importance of deck layout to boat operation, crew usage. The relation of line stoppers and winches. Each line had a winch prior to invention of line stoppers. Figure 6–14 Deck Layout

Vocabulary Bitter End. The inboard end of a line, chain, or cable. The end made fast to the vessel, as opposed to the “working end,” which may be attached to an anchor, cleat, or other vessel. Boom Vang. A tackle, usually running between the boom and the base of the mast, which removes twist from the sail by downward pull on the boom. Cleat. Fitting, usually with two projecting horns, to which lines are made fast. Downhaul. A line or tackle used to exert a downward pull on a sail or spar. Line Stopper (Rope Clutch). A clamp-type device that contains a cam for securing a line. It can be released quickly. Tackle. An arrangement of line and blocks used to provide increased mechanical advantage. Traveler. A sail-positioning system composed of a track on which slides a car attached to blocks to permit positioning sheet leads under load. Turning Block. A block used to change the direction of a line (such as a sheet or halyard) to make hauling more convenient.
