Description: Luffing is the act of adjusting the angle of a sail or crane arm to better capture the wind. In the context of sailing, it refers to the maneuver of changing a vessel’s direction to take better advantage of the wind, which may involve adjusting the sails’ trim. In the realm of construction and port logistics, the term applies to cranes that have the ability to modify the angle of their arm, allowing for more precise and controlled movement of loads. This technique is essential for optimizing performance in both navigation and material handling, as it maximizes efficiency and safety in operations that depend on wind direction or available space in a port. Thus, luffing is a crucial skill that combines an understanding of wind physics and crane mechanics, being fundamental for effective operation in maritime and port environments.
