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. It is a fine control which is used more frequently on racing sailboats than on cruising or day-sailing boats. [2]
Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel (e.g. fore-and-aft) and its shape, (e.g. (a)symmetrical, triangular, quadrilateral, etc.).
Gunter rigged Lobster 12.5. Gunter rig is a configuration of sail and spars used in sailing. It is a fore and aft sail set abaft (behind) the mast. The lower half of the luff (front) of the sail is attached to the mast, and the upper half is fastened to a spar which is approximately vertical and reaches above the top of the mast.
The RS200 utilises a single line asymmetrical spinnaker system and low sheet loads on the sail controls. It can be sailed successfully by pairs of sailors with combined weights of between 16 stone (100 kg) and 26 stone (170 kg). Both sailors hike; there are no trapezes or wings.
Now our current boats tend to seek optimum performance as the prime criterion. Boats tend to fall into the categories of (1) racer, (2) racer-cruiser, (3) cruiser-racer, and (4) cruiser; however, there is much subjectivity in the definitions and classifications. Cruising is sailing for the enjoyment of sailing and to reach destinations.
Boats may be sailed using a jib alone, but more commonly jibs make a minor direct contribution to propulsion compared to a main sail. Generally, a jib's most crucial function is as an airfoil, increasing performance and overall stability by reducing turbulence on the main sail's leeward side. [1]
Rigging of a sailing frigate. A sailing vessel's rig is its arrangement of masts, sails and rigging. [1] Examples include a schooner rig, cutter rig, junk rig, etc. [2] A rig may be broadly categorized as "fore-and-aft", "square", or a combination of both. Within the fore-and-aft category there is a variety of triangular and quadrilateral sail ...
The Keying was a Chinese ship that employed a junk sailing rig. Scale model of a Tagalog outrigger ship with junk sails from Manila, 19th century. The junk rig, also known as the Chinese lugsail, Chinese balanced lug sail, or sampan rig, is a type of sail rig in which rigid members, called battens, span the full width of the sail and extend the sail forward of the mast.
