The primary advantage of adjusting the cunningham is the speed and ease with which the luff tension can be changed while sailing or racing. By either hauling or easing the line, the tension in the luff can be changed, thereby shifting the point of maximum draft of the sail forward or aft respectively, optimizing sail shape and thus performance ...
As the boat tacks they change over. Another function of the running backstay is to adjust the tension of the forestay to suit the sailing angle and sea condition. In general, during a hard beat when the boat sails very close to the wind, the running backstay is tightened to increase the tension of the forestay. The genoa is sheeted in.
Rigging comprises the system of ropes, cables and chains, which support and control a sailing ship or sail boat's masts and sails. Standing rigging is the fixed rigging that supports masts including shrouds and stays. Running rigging is rigging which adjusts the position of the vessel's sails and spars including halyards, braces, sheets and ...
Running rigging is the rigging of a sailing vessel that is used for raising, lowering, shaping and controlling the sails on a sailing vessel—as opposed to the standing rigging, which supports the mast and bowsprit. Running rigging varies between vessels that are rigged fore and aft and those that are square-rigged.
Stays are ropes, wires, or rods on sailing vessels that run fore-and-aft along the centerline from the masts to the hull, deck, bowsprit, or to other masts which serve to stabilize the masts. [1] A stay is part of the standing rigging and is used to hold a mast upright.
The earliest B&R rig was the result of wind tunnel tests and research by Lars Bergstrom and Sven Ridder at Sweden's Royal Institute of Technology. [6] The first generation, built around 1970, included a backstay and was used on many production boats. A patent application for the B&R rig was submitted in 1973 and was granted in 1975. [1]
In a windsurfing rig, the downhaul is the primary load-bearing line which controls the sail's shape. Modern windsurfing sails incorporate a sleeve for the mast, and therefore do not have a halyard which tensions the top of the sail. The downhaul is tensioned early in the rigging process and is generally not adjustable on the water, and is ...
In 2005 a smaller 4.2 m 2 sail was approved, [9] which can optionally be used in favour of the standard 5.3 m 2 sail. [10] The smaller sail is more efficient than a larger sail that is reefed. The first 4.2m² national championships were held in 2010. [7] In 2020, after two years of development, a new 6.4m² rig for the Topper was introduced. [11]
