Luffing refers to the behavior of a sail or crane when it flutters in the wind. It can be caused by improper sailing technique or deliberate maneuvering. Luffing jib cranes are designed for close quarters and can be attached to existing cranes or rented.
Luffing is a sailing term that refers to the behavior of a sail when it becomes windy. As the candle flutters it begins to make a clicking or grunting noise that is very distinctive and easy to identify. In some cases a sail is blown by accident, and in other cases it may happen as part of a deliberate maneuver. The term “luffing” is also sometimes used in reference to kites and other types of flexible profiles that can also luff as they move through the air.
There are several reasons for a sail to drift. One is improper sailing technique, where someone does not handle the glider correctly. In this case, gloom can be a prelude to losing control of the boat. In other cases, a bulge sometimes occurs while a ship is pinning or under a similar maneuver that is designed to control the direction or angle of approach.
In addition to being audible, this phenomenon is also visible when the sail flaps in the wind. It may be a good idea to stay away from a boat with a rattling sail, as it may be trying to maneuver. As a general rule, more clearance is always better when it is available, because conditions at sea can become unpredictable, and leaving enough room for everyone to navigate safely can reduce the risk of accidents and other problems.
The term “luffing” also appears in reference to a particular type of crane, a luffing jib crane. These cranes are designed to work in close quarters, a common problem found on jobsites in urban areas. Using this style of crane also allows people to circumvent regional regulations that require crane operators to seek permission before swinging a crane onto neighboring land. With a luffing jib crane, the crane can be operated in such a way that it does not ride over land belonging to neighbors, thus avoiding the need to comply with such regulations.
This crane design is actually an accessory that can be installed on an existing crane, rather than a complete crane design. Individuals can purchase the attachment to upgrade to an existing crane, or they can order a crane with a luffing jib attachment from a manufacturer, depending on their needs. These cranes are available for hire or rental, for people who need a crane for a short period of time and prefer not to buy one.
