Jib

A jib is a type of adjustable arm on a boat's mast or a crane used for lifting and moving objects. On a boat, it extends forward, helping to catch wind and improve sailing performance by directing the sail’s shape and power. On land, a jib crane's arm can pivot and extend to lift heavy loads. Think of it as an extension that enhances control over movement—on a boat for better sailing or on machinery for lifting heavy items—making tasks more efficient and precise.
